OpenTX (TX16S) and SPM4650 (srxl2) telemetry problem

Post by dosh22 »

This is maybe not the "beginer" question, but i hope, someone can help me...

I have a SPM4650 on my quad, the reciever is connected on T2 port on the iFlight SucceX-E F4 V2.1 flight controler with Betaflight 4.2.4. I can control the quad without problems.

I have also the OpenTX transmitter (TX16S, OpenTX 2.3.11) and I want use the telemetry output from the reciever. But the telemetry looks like:

I don't get any usable data from the reciever....

My BF configuration (related to SRXL2 protocol):

feature RX_SERIAL
feature TELEMETRY
serial 1 64 115200 57600 0 115200
set rssi_channel = 0
set serialrx_provider = SRXL2
set serialrx_halfduplex = ON
set serialrx_inverted = OFF
set srxl2_unit_id = 1
set srxl2_baud_fast = ON

Have someone working telemetry between SPM4650 and OpenTX?

You should post in the multiprotocol module thread:

The newest Spek stuff isn't fully supported at this point, the devs need people with the equipment to get feedback.
