Hi,
I have a spektrum 4649t receiver (http://spektrumrc.com/Products/Default.aspx?ProdID=SPM4649T) in my new build. When I first powered it up the receiver was automatically in bind mode (rapidly flashing light), this surprised me because it doesn't have an autobind feature like the 4648 receiver, anyways I bound the radio to the receiver and it seemed to work because the light stayed solid. The problem is that every time I power cycled the receiver goes back into bind mode. I initially had soldered the positive wire to to 5v, negative to ground, and signal to the DSM2 SUMD pad on a Betaflight f4.
As for the Betaflight setup I turned on serial rx on uart 3 in the ports tab, in the configuration tab I put "Serial based receiver(Speksat, sbus, sumd) " as the receiver mode and selected spectrum 2048. I also set spectrum on channel mapping.
I checked in the cli that spektrum_sat_bind = 0
Then I found that in an rc groups thread some were saying that you needed to hook up the signal wire to a tx pad of an uart, so I soldered it to tx2, then in Betaflight I turned on serial receiver on uart 2. However this did not resolve my problem: the receiver always goes into bind mode every power cycle.
I also noticed that when I bind the receiver to the radio making the light solid, on the receiver tab none of the channel input bars move when I move the sticks on the radio.
Any Ideas?
