Can't permanently write airspeed

[paulh2oski]

I need to change the airspeed higher than default (0-4800). Using the commands:

+++
AT-Airspeed=19200
ATW
ATO

will let me change the airspeed until it is power cycled. As soon as I power cycle and try AT-AI0 it tells me that AT-Airspeed= 0

Note that I have done the same thing on AT-Serialspeed and it is permanently changed.

Thanks,

Paul

I believe I have figured out what is happening that is causing the issue. The command AT-AirSpeed gives a warning that it is going to overwrite other settings - Coding Rate, bandwidth, heartbeattimeout, TxToRxUsec, and one more that I forget.

However, I don't think it does and then when you cycle the power, these settings are still written and so the device reverts back to the default airspeed - 0 (4800).

When I changed the above settings individually, the changes were saved through power cycles.

The firmware should be changed so that when you change the airspeed it includes changes to each of these settings as it doesn't seem to be happening.
