Compass and home info not showing up.

[spyder0069]

Just started working with this tonight using an ESP32 chip. I am getting voltage/current/flightmodes and such but I do not get the compass, distance to home, home direction to show. I do show satellites and lat/lon. The sat icon is blinking.

Do these other options show up once armed or are they supposed to show up right away?

This is using a pixhawk if it matters. I appreciate the work and any help. :^)

If sats are blinking you don't get gps home set properly. Also check if your mavlink rates are like this in your parameters, and use the latest code because there have been updates:

(this is for SR1, serial port 1) SR1_ADSB,5 SR1_EXT_STAT,2 SR1_EXTRA1,5 SR1_EXTRA2,2 SR1_EXTRA3,2 SR1_PARAMS,10 SR1_POSITION,2 SR1_RAW_CTRL,1 SR1_RAW_SENS,2 SR1_RC_CHAN,5

Or modify the code where it's setting gps home, I'm guessing you're not getting the numSat or fix_type messages

if(fix_type > 2 && set_home == 1 && gps_lat > 0 && gps_lon > 0 && numSat > 5){

to

if(set_home == 1 && gps_lat > 0 && gps_lon > 0){

but I'm pretty sure you don't have the SRx_EXT_STAT set properly and ardupilot doesn't transmit the GPS_RAW messages.

I have the SR mavlink rates set properly. I just pulled the code last night. I have 13 satellites found and my GPSSTATUS=3 which means I have 3d fix. My GPSHDOP is 0.79.

I am indoors so I have not armed. Does it require arming to see the other items? I would have thought things like the compass would show without arming.

I have this all working on a minimosd so the output should all be there. This is also running a crossfire with control over mavlink on telemetry 1.

[d3ngit]

No, you don't need to arm. It should work without.

Try pulling out the crossfire for testing.

Wait. Are we sure you're not trying to set the osd elements for compass etc. that are set to 234 by default? This is a hack and will display the two numerical direction and dist to home in the lower right corner in place of pitch and roll angles like in the pic.

[spyder0069]

I found the problem. Your code needed to be changed to: if(fix_type > 2 && set_home == 1 && gps_lat != 0 && gps_lon != 0 && numSat > 5){

This is because my longitude which: gps_lon=-892446495

Now I have a solid satellite icon. It sets the _home variables.

I still do not get the compass bar or other home icons. Here is my config:

[d3ngit]

Thanks. I'll fix the gps check.

The elements you are trying to set are disabled by dji so we're reusing others to display things.

[spyder0069]

Ah. So the compass bar and other items in the betaflight config are not fully implemented. I got you.

[spyder0069]

Was there a list of items that are working?

[d3ngit]

Yes. Maybe in the future I'll add them but I'll try to fix the current bugs.

[d3ngit]

The ones that are set to more that 234 are working, and main batt voltage,flightmode. Others need to be sent too so they are all there.

[spyder0069]

Sounds good. Thanks for your input and efforts. I can probably pull things off the breadboard now and try a flight. The ESP32 worked pretty well for this as you have 3 hardware serial ports to play with once you relocate serial1 to other pins as to not interfere with the flash memory. Leaves the serial0 for programming/debugging off the usb on the dev boards. :^)

[d3ngit]

Ok. Good luck!
