Hi. Thanks for your good job.
I have a problem while compiling, error:
[cut] loraprs_service.cpp: In static member function 'static void LoraPrs::Service::rigTask(void*)':
[cut] loraprs_service.cpp:322:75: error: 'xTaskNotifyWaitIndexed' was not declared in this scope

Bad IDEs version?

Is it possible to create a repeater node using ESP32 to relay messages between few clients to extend the range ?

Ideally repeater modem consisting of ESP32 and LoRa chip will be mounted at higher location with powerful omnidirectional antenna and it's job will be to re transmit all the messages it receives via LoRa?

Thanks.

Hi!

Can you please explain what type of ESP32 module is used for your PSB design?

I have makes PSBs from Gerber from this folder

https://github.com/sh123/esp32_loraprs/tree/master/extras/schematics/gerber

...and ordered this ESP32 Wroom 32 - 38pins modules, like this

https://github.com/sh123/esp32_loraprs/blob/master/extras/images/esp32_38pin.jpg

but the rows of contacts is too narrow (actually the module rows is wider).

I'm trying to get direct messages working in TNC2/text mode. I'm using 2 boards running loraprs, one as iGate, the other as client connected to APRSdroid. Messages from APRS-IS to RF work. The ACK is generated in APRSdroid, sent to the client module and sent out but on the iGate I receive a CRC error. Please see the console output with LVL_TRACE attached.

(Messages from the client to other stations work fine and the ACK is correctly received)

ack-crc-error.txt

1.Do I need to make any other changes to config.h (besides CFG_KISS_EXTENSIONS true) to use this project together with Codec2talkie.

2. Is it possible to use the settings
   CFG_TEXT_PACKETS true
   CFG_TEXT_PACKETS_3 true
   when working with Codec2talkie?

I'm trying to connect the rf4463F30 module from the nicerf manufacturer, it's si4463, but its pins are called differently. I'm afraid to disable the module by incorrect connection. Standard modules like E22-900m22s do not raise any questions.
https://www.nicerf.com/item/1w-rf-module-rf4463f30

Issue seems to be in loraprs_service.cpp lines 505ff:

  // TNC2 text mode
  if (config_.EnableTextPackets) {
    String textPayload = payload.ToString();
    bytesWritten = textPayload.length() > (CfgMaxPacketSize - 1)? CfgMaxPacketSize : (textPayload.length() + 1);
    textPayload.getBytes(buf, bytesWritten);
    buf[bytesWritten-1] = '\0';

I updated above lines to work. Still, it should not work as that because we are reading more bytes than we should have in textPayload. Still, reducing textPayload.getBytes(buf, bytesWritten-1); again misses the last character of the message. I don´t know what is wrong here and how to properly fix it.

When selecting board t-beam in arduino, it says sketch too big when compiling.

Reciving station got this after LoRa Modul has digipeated packet.

The last packet u can see on the screenshot is sended as beacon from the Modul ( Sketch ) self. The first is sended via a kiss connection to a linux ax25 device and was digipeated from 2 different moduls.

The trace from the digipeating station for the 1. packet show this.

Hope it help a bit. Seems there are more then just the invalid call issuse , because axlisten shows EAX25 Protocoll also DAMA ..

Maybe it would be possible to digipeat all kind of packets, not just UI Frames.
Maybe digipeting all Packets would be easier as well because u need just flipping the bit on the end of the own call in via address space ..

But i know.. It's easier said than done.. Was just a idea .

If u need some more information about AX.25 Protocol i found this quite helpful. It's in German but maybe Google Translator helps here..
TNN-Manual https://github.com/DeltaLima/TheNetNode-CB/blob/master/doc/tnn178.pdf
From page 121 you will find detailed definitions of the ax25 protocol.

Thanks, 73 and Good look ..

Update:

I dump this directly from a third device conneted via serial port.

dump.txt

Update2:
Another Dump..

dump2.txt

at startup it gives an error 707 or 705. If NReset is connected to pin26, then the error is -707. If you connect NReset to gnd, then the error is -705.
Please help me figure out what is the reason.

Although the beacon was sent it receives an error: TX error: -5
Unfortunately, the device is not receiving anything from LORA and stops flashing the LED on the board.

Further to our other chats,. I see that there is no collision control right now.
I see that KISS has P-persistent CSMA as part of the protocol.
And the Mysensors library I use RFM95_sendWithRetry with some form of CSMA.
I think that using APRS on these Lora units is really cool, however the time-on-air at large spreading factors is quite high.
What do you think of implementing CAD/CSMA to take advantage of the fact that we are generally using transceivers for our Lora APRS so we can have better control of the traffic flows?

Hello, would you be so kind as to tell me the connections between the pins of a wroom-32 38 pins and an rfm95?
Thanks in advance.

Would it be possible to add bluetooth passthrough ?

For example use a bluetooth terminal application and sent a text message between android phones.

Lora register have a bit set to 1 when packet is currently decoded by radio module. I made test on these bit and the bit remain at 1 until packet decoding complete and stored in fifo. You can use this bit as carrier detect. Here my code: (Using standard persist/slottime)

This code work perfectly, have avoid any on-the-air collisions with other packet. I use them since two year with my own lora aprs implementation. Right now I watch witch mode become standard and I would convert my network to most common protocol.

Hello, can this firmware be used on the lora32 v2.1 1.6 card?
I would love to be able to use this cheap card as KISS TNC for mobile phones.
Thank you!

uncommenting the usePrefix3_ section in kiss_processor.cpp line 344ff:

bool Processor::receiveByteRaw(byte rxByte) 
{
  if (isRawIdle_) {
    if (!onRigTxBegin()) {
      return false;
    }
    // if (usePrefix3_) {
    //   onRigTx('<');
    //   onRigTx(0xff);
    //   onRigTx(0x01);
    // }
    isRawIdle_ = false;
  }
  // NOTE, TNC2 uses \n as a packet delimiter
  if (rxByte == '\n') {
    onRigTxEnd();
    isRawIdle_ = true;
  } else {
    onRigTx(rxByte);
  }
  return true;
}

seems to resolve the issue - but I am not sure about possible side-effects.

Hi, I have this error: 'LoraPrs::Service::serialBt_' will be initialized after [-Werror=reorder]
Error is in loraaprs_service.h on row 106
Please help me.

Can you add support to SX126X Lora chips?
I been trying to change Lora library dependency to RadioLib without succeed.

Hello,
I'm trying to figure out how to adapt the code to the ttgo tbeam as it seems a nice device for aprs use.
I've disabled the aprsIS and wifi part to be able to fit the code in the tbeam, the idea is to only use it as a kiss radio modem, without gateway feature for now. I've changed the lora module pins to fit the t-beam.
It pairs with aprsdroid and send a lora packet as far as I can see on the sdr. But the lora32-v2 using the lora-aprs/LoRa_APRS_iGate code doesn't decode the packet (it does when I'm using OE5BPA tracker code).
As I am a total noob in development, I thought I should ask if you have any idea or suggestion I could try to make the code run on the t-beam. This device and aprsdroid would be a good match for a very nice aprs package if it can be adapted.
Thanks for any help and for the work you already did !

It would be useful if modem will connect to home WiFi network or run as AP, so that instead of short range Bluetooth, application such as Codec2 Talkie, Direwolf or Xastir will be usable through home WiFi, which has longer range. So modem could be put to higher elevation, such as roof top in a waterproof box for larger coverage.

• Add option to enable AP
• Add option to enable KISS over TCP/IP
  • In this case app must listen on a default KISS port and when client connects communicate with him by the given socket

Hi,
may I ask for some help?

I´m not able to TX/RX any APRS packets via antenna.
I see, the board is connected via WiFi to APRS Server and is sending beacons to the server.
But, no RX or TX via antenna is possible.

I´m using a Heltec WiFi LoRa32 V2 board and defined
#define LORA_RST 14
#define LORA_IRQ 26
#define SS 18 (I have added it later as I thought it could be the issue as no definition is shown)

I put my other iGate next to it, testing any TX
and also my Tracker , testing any RX.

I have installed different SW and see with that SW,
I´m able to RX/TX any LoRa packets, so HW is not defect.

and clue

regards

Hello

Thank you for your hard work coding this project. I succesfully flashed a TTGO Lora32, to use it by a standalone iGate, its working OK except for the APRS-IS connection. The packets dont reach the APRS-IS network, looks like they are being dropped by the APRSC Server.

I tried with the server of a friend ( http://radioaficion.pro:14501/ ) and noticed the packet RX count sent by the iGate on red on the client list.

I dont know what is wrong. Any help is apreciated

Hi there.
Would it be possible to interface the Android Codec2 talkie app with your arduino code with different RF modules to send the raw audio packets through?
If so which parts of your code would have to be used or modified?
I do realize this question is not directly related to your project but I think this should be possible so any hint is highly appreciated.

I have load it to TTGo LoRA board. Set CFG_IS_CLIENT_MODE to false
#define CFG_DIGIREPEAT true
#define CFG_RF_TO_IS true
#define CFG_IS_TO_RF true
#define CFG_BEACON true
Also configured Wifi, APRS login.
However, the beacon never showed up on APRS map and never forward any other LoRA APRS to APRS-IS
What could possibly go wrong? The LoRa board did successfully get an IP address from the router as I could see it from router DHCP table.

Hi,

Building with pio run -e esp32dev_sx127x_igate gives an error:
src/loraprs_service.cpp:302:41: error: no matching function for call to 'SX1278::setDio0Action(void (&)())'

Regards,

There are quite a few LoRaWAN networks coming up that provide a lot of useful coverage in the ISM band. Examples are Helium and The Things Network. In particular, Helium has LoRa gateways in almost every major city. There is no technical reason these cannot be used as two-way i-gates for esp32_loraprs TNC devices.

The benefit to esp32_loraprs would be that anyone could use the project to send data to APRS-IS over RF, immediately, and without setting up any infrastructure. There is a strong chance that, with this feature, a user could download the repository, flash it to their ESP32 board, and see their packets sent to aprs.fi (and others) right away. Currently, there is little existing dedicated ham radio LoRa infrastructure, and there are no standard frequencies and settings. This may lead to frustration among users who want a solution that "just works" in the sense of getting their packets on the map. We could duplicate the experience which users of commercial radios with packet TNC's on AFSK 144.390 currently have, without the need to bootstrap our own system.

I suggest that this would be implemented as an optional switch in loraprs_config.h, alongside a switch for sending RF packets point-to-point. Both, one, or none could be selected. This would only be available for radios on 915 Mhz (North America), 868 Mhz (Europe) or 470 Mhz (China).

This feature would need to be combined with a process running on a server to forward packets between the LoRaWAN and APRS-IS services. I have already created this and am using it for my own testing.

One potential problem is the fact that LoRaWAN uses encryption to send packets. This could be mitigated by publishing the encryption keys used for this particular application EUI, so that anybody could decode the packets. On the other hand, this system is similar to just using the internet to forward packets to APRS-IS over wifi, over which the use of encryption has never been problematic. I'd appreciate any feedback or clarity on this.

I'm submitting this as a feature-enhancement idea because I know how to make it work, am essentially using it for my own purposes, and wanted to know if it sounded like a good idea and something that could be useful to the community.

Is there a way to contact you to learn to decode and encode ax25 packets to avoid copying all without understanding what you did?

This is for a Lora Tracker in developing

I've got some crashes like u see in the topic.

I can't verifying crashes on your original version because i had to modify the sketch a bit so that it works with RadioLib and SX1276 ( 868 MHz ).

But it seems the crashes decreasing when i increase CfgPollDelayMs to 10. Now i have set it to 15 and it seems ok but i still testing.. ( Get still some losts of ip connection from the Modul but i can't tell if it's related to the crash or just to a weak wifi connection )

Another think i did, but don't laugh, i am just a amateur, i commented out
delay(CfgPollDelayMs);
in
Service::processIncomingDataTask
.

I came to the decision to do so, because i googled the problem.
It seems to came to this problem when u delay a secondary task ( like a thread, like i understand).
And like i understand Service::processIncomingDataTask is a secondary task in ISR Mode.

Like i said.. This both changes seemed to work on my side. I also discovered that the Moduls are really hot after they crashed..

So it makes sens to increase CfgPollDelayMs to get load from the CPU and it wouldn't be necessary to comment out the delay(CfgPollDelayMs) in Service::processIncomingDataTask .

I had some feedback from the TTN forum regarding my APRS IGate setup:

https://www.thethingsnetwork.org/forum/t/the-amateur-radio-corner/5252/68

Opinion on syncword.

Hello. When using the E22-400M30S and ESP-WROOM-32 38PIN on the PCB from the project, have I written the pins correctly?

• It would be useful if modem could be used with Android Phone in USB-OTG mode.
• So data will be transferred through USB serial port instead of Bluetooth.
• In this case user can power modem from the phone USB-OTG port and use the same port for data transfer by APRSDroid and Codec2 Talkie applications.
• Need to disable debug printing usage to serial when USB mode is enabled and use serial for data transfer only, default baud rate could be changed for both APRSDroid and Codec2 Talkie, so keep existing one
• Additionally, user can print 3d holder for the modem.

I have installed your great app https://github.com/sh123/codec2_talkie.

can you make simple one file sketch for ESP32 to use with above app removing all Kiss, APRS and WiFi Stuff for general purpose (non HAM) use ?

I am not well versed into HAM radio stuff. If there is simple sketch dealing with codec2 raw packets with LoRa transport my plan is to use it as a template to implement some newer LoRa chips like SX1262 and SX1280.

Thanks.

I really like this idea.
Im building a testing one today here in Cape Town.!

Hi,

i use LoRa as a additional Port on my Node ( TNN ) for testing the possibilities of Lora and how useful and piratical it is.
So i don't use it just for "unprot" Data transfer like in APRS Application.

So i need Bandwidth or better speed.
The main speed factor on simplex isn't the baudrate. The main factor is how many packet i can send at once.

Sure, the payload length is a factor too because of saving header but it seems limited to the LoRa Coding rate.
If i use coding rate 8 i double the airtime ( overall packet length ) . So a AX25 pac lengh > 100 seems exceed the LoRa Pac lengh.. Or the LoRa Chips can't handle so much air time.
I am still testing it.

Back to topic.. Sorry but maybe
It wasn't possible to send more than one packet at once until i increased the preamble length to 16.
I got the issues on both librarys ( LoRa and RadioLib ) also on different devices (T-BEAM, Heltec WIFI LORA 32 V2, Heltec Wireles Stick ) and the solution worked on both libarys for me.

Just a idea: Maybe the kiss cmd for txd can be used to set preamble length. But there are issuse if preamble length isn't set the same on both ends.

int state = radio_->begin((float)loraFreq / 1e6, (float)bw / 1e3, sf, cr, sync, pwr, preamble);
LoRa.setPreambleLength(preamble);

Thanks for your work.. I love this AX25 shit.. It isn't perfect but that's it what it makes interesting . .

Hello! This looks awesome. I would like to try it out, are there specific boards this is compatable with? For instance could I use it with the TTGO T-Beam ESP32?

Thanks! KD8IAY

According to this document, default frequency shold be changed from 432.500MHz (AX.25/1200baud/9600baud AFSK or FSK)
LORA-APRS-433-MHz.pdf

Is it possible to work in tracker and digirepeat mode at the same time?

Hello,

at first, thank u a lot for u work. Seems Lora can be interesting as a cheap and simple to made option as an Secondary entry to our free ax25 Network in Germany ( mostly on CB Radio and via AXIP ) .

The Sketch seems to big for the T-Beam. Also i got issues while compiling it with LoRa libbary.
"'loraprs_service.cpp: In member function 'void LoraPrs::Service::setupLora(long int, long int, int, int, int, int, int, bool)':
loraprs_service.cpp:295:7: error: 'enableCrc' was not declared in this scope
if (enableCrc) {"

I solved it for me like u can see in the screenshot.
I also solved for me the "Sketch to big issues" be commenting out the Bluetooth section in the setup() routine.
In the config i allready cleared out the BT device name (
// Bluetooth
#define CFG_BT_NAME "" // set to empty to disable Bluetooth
#define CFG_BT_USE_BLE false // set to true to use bluetooth low energy (for ios devices)
) .

I already spotted some other issues but better I submit it as an other Issues here because it's another topic..

Thanks .. .. .
