[Davide1986]

Hi, I just upgraded to the latest version of the radio ersky9xr..e my module Assan x8j stopped working even if I select the protocol Assan in the settings of the model !! please help me !!

Use the same protocol you were using with the X8J, what was that?

It should work as before you upgraded.

Hello thx for reply!
With the stock firmware the module work well..but with last version not work! I have the 2 module of assan 8JX the last v2 work but why the v1 not?

I assume you are using PPM as the protocol. From r213 onwards I inverted the PPM output signal to make the polarity sense the same as other transmitters. It may well be your V1 unit only works with a specific polarity PPM signal. You may select the polarity in the protocol setup, it's called "Shift Sel" and is either POS or NEG, try changing to the opposite of the one you have selected.

Mike, wouldn't it be better to change the name to "polarity"? It seems that "Shift Sel" doesn't mean much to most people I remember some not finding it easily in the past. I was one. I knew the option was there but just couldn't see it as the name didn't make sense to me I know, I'm dumb..

Thanks
