how to set SF?
I can`t find where to set sf and what is default value of sf?

We are using the loop read example python script: ap-Lib-5-lora-LoopRead, and we're experiencing some problems while receiving the data.

1. We are only able to receive the first the transmission, after that all the subsequent packets are empty.
2. We have to reset the device iFrogLab LoRa USB Gateway to receive more data. But as before, we only are able to get the one packet and the subsequent packets are empty.

Basically, we are using a iFrogLab LoRa USB Gateway as a receiver and nRF52 Dev Board (with a Semtech LoRa SX1272 transceiver) as a sender. The sender sends data every 1 seconds, while the LoRa USB Gateway is receiving the data. The following is a snippet from the python script:

while True:
  data=LoRa.FunLora_6_readPureData()
  print ("{%d}" %(len(data)) + ",".join("{:02x}".format(x) for x in data))
  time.sleep(1)

In the first iteration of the while loop, we send the respective commands to read from the iFrogLab LoRa USB Gateway device.

0xc1 0x06 0x00 0xc7

The response is as follows (which correspond to the data we send from the nRF52 board):

0xc1 0x86 0x22 0x19 0x63 0x19 0x00 0x00 0x07 0x08 0x0b 0x00 0x00 0x00 0x15 0x0e 0x00 0xe3 0x00 0xe0 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x1a

However, for the subsequent iterations of the while loop, we get the following response from the device after sending the commands for reading (0xc1 0x06 0x00 0xc7):

0xc1 0x86 0x02 0x00 0x00 0x45

If we restart the script again (reseting the iFrogLab LoRa USB Gateway device, configuring the modes, etc) we are able to get just one data packet again. Then, as before, all the subsequent packets are empty.

0xc1 0x86 0x02 0x00 0x00 0x45

We did the test on Windows and also on Linux, and the result is the same. Furthermore, we did a test using two iFrogLab LoRa USB Gateway, one acting as receiver and the other as sender, and everything works with that same script (ap-Lib-5-lora-LoopRead.py).

Has the iFrogLab LoRa USB Gateway been tested for receiving data from other LoRa compatible devices?

Can anyone give us hand try to solve this issue?

請問ifrog的網站今天上不了，是因為伺服器更新還是其他原因呢?

We use the files in the library you have given
(IL-LORA1272/Samples-Arduino/Ver2/iFrogLabLoRaLibrary/sample03_Read_Broadcast/)
Some questions would like to ask you

1. Sometimes the information received will be lost
2. Received data will be retained, can not be cleared (try by reset & using memset can not), can only re-
   plug the power to clear
   3.error message appears frequently on Serial Monitor(Arduino)

Hope you can give me reply, Thanks

I purchased your USB Lora SX1272 device and am looking at your source code. Based on either the Arduino or Python examples I don't see anything more than just send/receiving test datasets in there. The ifroglab.py Python library has root functions for sending/receiving and actually it just appears to be reading/writing to the UART serial port.

Where is the source code or API for actually setting parameters in the device? For example, I am in the USA so I need to set the Lora frequency to be 915.0 MHz. An Arduino shield I have on another host has those types of settings in their library, as well as setting transmit power and other things.

From what I see, the source code for IL-LORA1272 just appears to be a test wrapper over the standard UART serial functionality...
