GPS: Foxeer M10Q 180 GPS 5883 Compass

Hello,
As in the title - my GPS/Compass is not recognized in HW ID but the device itself is running (stable green light). I have tried to swap Rx/Tx on 3 different UARTs, still not working. I am afraid that FC board is broken but not sure how to troubleshoot further.
In the bottom image GPS is connected to T1/R1. Tried T6/R6 before and T2/R2 (this one is now connected to my Raspberry Pi which i use to forward using Mavproxy)
Please keep in mind that im just starting with that kind of hobby :slight_smile:

Here i have GPS everywhere because i read somewhere that port number on board may be different than the one in mission planner.

Well, then read it where it’s right for Ardupilot.

And disable all the ones not connected.

Disabled - did not help.

Tried to swap T2/R2 with T6/R6. Connection to my RPI worked so the port is working (worked much slower than 2 but worked).
So now I’m sure UART2/6 both work.
GPS on UART2 still not appeared on HW ID. Tried changing baud - not worked.

Reset all to default and connect it to Uart6 which is the default port for GPS after firmware flash.

It helped!
Didn’t think of that before.
Thank you. <3

Cool! Sometimes after changing a bunch of parameters something get’s left behind and messes things up :slight_smile:
