i am using a Bandit BR3 ExpressLRS 915MHz and it is bound and linked to TX15 900MHz internal module. Wiring continuity good. TX/RX crossed correctly, i have swapped them more than once to see. All parameters correct.
my issue is that the Pixhawk 6c is not receiving any RC input from the BR3. I try to calibrate radio and nothing moves.
when i check with a multimeter i get 5v from the 5v, 2.7v from RX(on the BR3), 2.7v from TX(maybe this is abnormal? TX/RX should be 3.3v).
Under status:
rxerrors : 0
rssi : 0
ch1in : 1500
ch1out : 1100 all the other ch()in/out values are static and 1500/1100/0
I am plugged into telem 3
SERIAL5_PROTOCOL = 23, SERIAL5_BAUD = 115, SERIAL5_OPTIONS = 0, RC_PROTOCOLS = 1 or 512 both should work, RC_OPTIONS = 8192, RSSI_TYPE = 3
To troubleshoot i rewired the Br3 to go into the SBUS RC port and it still did not work(i changed the lua protocol to sbus too). Model matching is off. The receiver binds with no issues.
Does anyone have any advice?
