GPS support? #12

Closed ketilmo closed 1 month ago

ketilmo commented 1 year ago

Hi @xoseperez,

Thanks for creating this excellent basicstation implementation. Much appreciated! I have it running on an RPI with an RAK2287 hat with a GPS antenna connected using balena. I see references to GPS time in the logs, but I need help to verify if basicstation is using the physical GPS for timing or not. Hence, is GPS supported, and should it activate automatically?

Latest 2.8.4 version includes GPS support via the GPS_DEV environment variable. Set it to the GPS device.

Fantastic @xoseperez! Thank you so much for implementing this. Do you happen to know what the device path would be on a RAK2287?

Well, that depends on the host, not the concentrator. The RAK2287 (only version with GPS, mind there are versions without) exposes the GPS via UART. Depending on the host/hat it might be mapped to an available UART.

On a Raspberry Pi, the easy way is to disable console over serial with raspi-config but keep serial port enabled. This should map the GPS to /dev/ttyS0. You can also use dev/ttyAMA0 by adding dtoverlay=disable-bt to the /boot/firmware/config.txt file. Some say it's more stable this way.

Thanks for a good explanation, @xoseperez! This is very helpful. Have a great evening.
