I have a Spektrum SPM4650C SRLX2 receiver I’m trying to use with my Pixhawk 1 but cannot get it working and not seeing any movement from the bars in the radio tab. I’m using the latest 4.14 copter version and have the signal wire connected to the TX pin on Telem 1. I have serial1_protocol = 23, serial1_options = 4 and rssi_type = 3 all set.
I have tried two different receivers and two different wire connectors as well as trying my orange cube and tried wiping the settings so I’m starting with default setting with no positive results. The receiver has power and I can bind it but cannot get anything into arducopter.
Any advice on things I can check?
Thanks in advance.
