Using MP terminal can I send RTS1=1 to set a bit high on the APM2 like one of the free analog ports ?
The send is to the remote 433mhz radio to set a bit somewhere to signal a FET to heat up and cut the nylon cord attached to the high altitude balloon.
This is what I am basing it on.
The AT commands available are:
all of these commands, except for ATO, may be used on a connected remote radio by replacing 'AT' with 'RT'.
I need to activate FET by 433mhz radio NOT the RC stuff because of range.
