I figured out that i get a very poor range while using openlrs (hawkeye Tx/Rx) with APM (mini arduflyer from rctimer). Indeed, I get a very good range while testing in the city (maybe 700m with a lot of batiments), but when I try again with APM, I get beeps at less than 1 meter, and I can't even go outside to walk around without any almost continous "beeps".
Did somebody already experience this? Do you know what could be the exact source and how to get rid of?
APM "mini arduflyer" from rctimer
GPS NEO-6M with compass from rctimer
Power module for APM from rctimer
bluetooth module connected to APM to connect to APM planner
Any help would be appreciated!
