AR9X telemetry

Post by michel49 »

I have a TH9X/AR9x/Ersky9X-r220 with a multimodule stock FW; I can bind in serial mode with my D8RII but I can't get telemetry either PPM or serial mode which works well with the DJT module.

I'm not sure where is the issue: wrong parameter in ERsky9x-r or multimodule FW ?

More information please.
Is the multi module installed inside the radio or in a module case that you plug into the module bay, the same as the DJT?

If this is the case and the telemetry works with the DJT, then the issue is with the multi module.. I think earlier versions of the module needed a couple pads jumpered so it would send telemetry out..

Please see here, and check your board:

For the Ar9x board you need to make sure that the multi module code is compiled with "#define INVERT_TELEMETRY" enabled.

But please for now just check that your multi has the solder bridges mentioned on the link above.

Hi Joao,

Yes, the two bridges are soldered and the module is in JR bay; I can't know the FW: it is the stock one...I wait for the programmer...of course I tried inverted and non inverted in the telemetry menu; in the same way I don't have telemetry in DSM mode where all worked with DJT module and Orange module.

Maybe I have to update the FW of the 4-1 module ?

Thanks for your help

yes, for the 4 in 1 module to work with the Ar9x board you will need to compile the code for it with "Invert Telemetry".

Wait a second, I think there is something you can try to find out if thast is the problerm.
I think the Ar9x board has a little jumper to invert COM1. I think you can place the jumper differently for non inverted.

See picture. Move jumper to "RX1 NOR". See if the telemetry now works. If it does, then you need to flash the 4 in 1 module with the Invert telemetry firmware as said above, and put the jumper back as it was before on "RX INV", or the DJT and XJT modules won't work anymore..
