No support for serial GPS???
I was so excited about the idea of creating a framework for PITS and then something like that:
We cannot use the Pi I2C ports because of a hardware limitation in the BCM processor, and we cannot use the Pi serial port if (as is likely) that is in use for RTTY transmissions.
Why should I use the RTTY with lora at the same time? It doesn't make sense. I would like to use your framework for the next HAB flight in September, but without serial GPS support, it will be difficult.
By the way, I use GPSD on my zero :)
The software was written for the PITS board which uses the serial port for RTTY, so uses I2C for the GPS.
I'm happy to include serial GPS support so I'll treat this a feature request. Won't be for a couple of weeks as I'm working away and don't have a serial GPS with me anyway.
As for GPSD, no, it's a pain; support will be direct to the device.
Some GPS devices need to be put into "flight mode" for HAB use. PITS uses a UBlox GPS and the existing code sends a UBlox command to do this, as will the new serial code. If you use some other GPS and if it also needs such a command, you will need to send that yourself; I'll provide a function you can use for that.

Hello please check my change to connect a serial device: https://github.com/xpix/pytrack/commit/9f63b70295dd548df2fd8e3ae918a916a0f5518d
Sorry for the tabs, i removed them here: https://github.com/xpix/pytrack/commit/981707596e60230d7e39c7b7d2d79797c8828361
@daveake what do u think about my change to support a serial device? It's ok or you think we need some improvements?
I will take a look next week.
If you intend to use this with any GPS other than UBlox, please be aware that some devices require to be placed into "flight mode" or "balloon mode" in order to operate above 10-12km.

Cool, i dit it. Please check this one: https://github.com/xpix/pytrack/commit/9f63b70295dd548df2fd8e3ae918a916a0f5518d#diff-5682ac9c42840bb2ebb5831b4d8c3078R115
Which GPS do you plan to launch ?
