Device Frequently disconnects throws errors -19 and fails health check

General
1

I have a device EKH03, that is has a good link to the AP, but will frequently stop working.

I first noticed when running

morsectrl mcs 2

and got a -19, didn’t think much of it.

but the device frequently loses connection and I have to power cycle it. it then reconnects and quickly disassociates from that AP.

Hi @Luisschubert , sounds like the host is no longer able to communicate with the chip for whatever reason (FW crashing or HW failure).

If it’s a FW error then you might be able to get more information on it with the following:

stty -F /dev/ttyS1 115200
cat /dev/ttyS1

then try to trigger the bug. This will let us know if the chip firmware is reporting any errors
