iNav 5.0
matek 722SE 5.0
Radiomaster 16s  Edge 2.7.1
Bat 4S 15.2V (storage) for test

All symbols ready to arm but will not arm because flight controller beeps rapidly and continuously when battery connected. Calibrated Tx, double checked all that I know about but could not find problem. Wish I spent more time flying

If this is an analog FPV system build then turn on warnings in the OSD and it should report whats stopping the quad from arming.

Does it have a GPS module? Do you have enough satellites for a GPS fix?

What flight mode are you flying? Angle mode or horizon mode will require the accelerometer to be calibrated.

Go into the CLI and type status and report back what it says.

Also connect to INAV and see if the Configurator lists any warnings.

set battery_capacity = 3300
set battery_capacity_warning = 3300
set failsafe_throttle = 1200

Looks like multiple problems. I dont understand VTX not detected because it works. It was in angle mode and received nav error?
Havent changed Batt capacity. Usually use cell voltage

GPS fix ok. accelerometer calibrated.

iNAV not posting warnigs

Did you test the arm switch and transmitter sticks on the INAV Configurator Receiver tab? Do you have an arm switch setup in the Models tab?

There are no serious errors with the status command output.

Thanks for your help. In the mode set up the arming switch was backwards. Why I didnt spot that obvious screwup, I dont know. I will be using that status dump in the future.
