Sky Viper journey transmitter

Also something to check: The expected chipset. Look in the RADIO section of the parameters for BRD_RADIO_TYPE.

There are 3 types available here:

1 CYRF6936 is the selection for the V2450GPS
2 CC2500 is for the Journey
3 BK2425 is for the FURY and SCOUT

There’s a possibility that the Master got set to a different chipset selection on check-in, maybe? Check this param and if it’s not correct, change it. If it was off, it won’t connect to the corresponding flight board.

Hello Matt

This is what I builded

But CC250 is FRSKY ? Do we need to set a different radio protocol on line 66 ?

BTW did you had a chance to look at my blog Vision Positionning Experiments using SKYVIPER

Has anyone actually used a standard Tx (Taranis, etc) with the Journey?

From what I’m reading here, the Journey uses DSM protocol over a CC2500 radio link. I assume this combination could be added to OpenTx, but AFIK, the Frsky protocol is usually used with the CC2500 radio.

Assuming my assumptions are correct, should it be possible to fly using Mavlink over WiFi?
