GPS sharing about ecodroidgps HOT 16 OPEN

Great to hear that you got a solution via gpsd! Although I'm not sure if it would be helpful in your case, but just wanted to mention that ecodroidgps has a tcp server mode where you can let multiple clients connect concurrently to read the nmea - you can enable this by either changing the config file or the code "tcp_server": "0", to be "tcp_server": "1", in line 38 of https://github.com/ykasidit/ecodroidgps/blob/master/ecodroidgps_server.py (and stop the server, delete the "/config/config.ini" file if exists) then start the server and you can connect to tcp port 8888 on the host (implemented in file https://github.com/ykasidit/ecodroidgps/blob/master/edg_socket_server.py) to get the nmea concurrently via multiple tcp socket (or socat) clients. About using gpsd that's a great idea thanks! I'm still not sure if it will be able to relay all the non-nmea binary UBX or NTRIP protocol payloads (for RTK mode) to/from the device or not (and never tested yet haha so will keep as is for now).

OK, I've just realised that it's possible to run a pseudo serial port forwarding data from gpsd via gpspipe - https://gpsd.io/gpspipe.html - so it should make a trick to share a GPS to many destinations including ecodroidgps.

But anyway it would be I think cool if ecodroidgps utilises gpsd instead of reading the sensor directly itself.

Thanks for the hints, I will study carefully your software on days, I have not noticed your socket server indeed. The most amazing is the fact you did exactly what I planned to do :) My use case is I am preparing a motorcycle computer which has access to internal bike computer and GPS in the same time, where I can relate for example engine RPM to precise location given by F9P sensor with large antennae attached and also fed my Andorid phone with more precise location than its internal sensor.

It's a pipe which serves data from gpsd to ecodroidgps, if somebody will be interested

@ykasidit could you please tell me where this name.txt comes from and how it should look like?

from ecodroidgps.

OK, I realised by trying and testing I need to set in config ble=1.

I can see that error:

python3: can't open file '/home/pi/bluez-gatt-server/bluez-gatt-server.py': [Errno 2] No such file or directory

Does it mean that some other repos than ecodroidgps and bluez-compassion are required?

And later I am continuously getting this error:

Hi! Thanks for another hints.

https://github.com/ykasidit/bluez-gatt-server uses python2 which is not available at newer operating system versions :(

I will have a look today if my programming skills are enough to propose patches :)

from ecodroidgps.

OK, i made a pull request for bluez-gatt-server fixing compatibility with python3 in files used by ecodroidgps.

But I don't not fully understand how to replace getbuf with memoryview - maybe you could have a quick look into that? it should be a minor issue for you as it appears in three lines only and you understand your own code for sure :) 👍🏿 :)

Hi mate! Are you making any progress? If not - could you please say if your intention is to continue this project or I should rather treat it as abandoned and seek other solutions?

Hi! Please do not understand me wrong, it's a free opensource project and I realise that all of us are doing it for fun - so no pressure. I was just curious if you still planning to work on it. If yes - fantastic as it's the best one I found. My main interest is a bluetooth service to mock location on Android. I'm working meanwhile on using influxdb to store geo-temporal data available from all sensors on my motorbike, but it's completely independent from ecodroidgps. It also will be GPLed when I have something useful to share.

OMG it works!

I was absolutely sure I need BLE to have it running!!!!!!!!!!!!!!!!!!!!!! I have not even tried with ble=0 before.

I can confirm it works with unselected "ecodroidgps broadcast device mode" in your Bluetooth GNSS app with this /config/config.ini:

[main]
spp = 1
ble = 0
gap = 0
tcp_server = 0
gpx = 0
nmea = 0
baud_rate = 115200
pyserial_read_timeout = 1.0
max_readline_size = 4096
max_read_buff_size = 20480

It seems that for my purposes everything is working as it should now. I am shocked and really grateful for your help :)

If you plan to fix the other features, please remember that GPSD is doing 90% of your job already and provides very stable API. Please use the newest version of it as comparing to package available in Debian it fixed many bugs.
