RX RSSI not working

ArduCopter Copter 4.5

Hello,

I have gone through the RSSI Tutorial and completed an RSSI configuration for the Auxiliary PWM Input option. The Ardupilot flight controller (CUAV Nora+) still has no sign of reception of the RSSI signal. Below is my current configuration:

SERVO13_FUNCTION: -1
RSSI_TYPE: 4
RSSI_ANA_PIN: 62
RSSI_CHAN_HIGH 2000
RSSI_CHAN_LOW 1000

I have tested the RSSI output signal from my receiver. It is present with a 3.3V high pulse. Right now I am testing without adjusting range. I just turn on the transmitter and turn it off again. When the transmitter is off, RSSI outputs a 176us high pulse. Then when on, the RSSI outputs a 3640us high pulse. Maybe both being out of range is an issue? I would assume that any pulse over my high setting of 2000us would appear as 100% signal strength.

I am watching the RX RSSI signal in the quick-view.

Oh my goodness! I just needed a reboot! It’s working now.

I would also like to have a RTL response when controller signal is lost. Is the RSSI signal viewed for a RTL command when acting on a loss of signal? Or does this RTL response only look at the CPPM input?
