Witch tx module for 9x r pro and 9x8cv2 Rx

Post by gborras » Sun Nov 05, 2017 9:56 am

Hi, new to this forum, no english native, so... sorry in advance...
I'm looking forward to buy a turnigy 9x pro radio, and give my lovely old 9x to my son.
The question is very simple.
Wich tx moduke should i take to be able to use my new 9x pro with the old 9x cv2 receivers?
Sorry if the answer is already in the forum, but I'm quite lost with those afhds dsss dsmx and so protocols.... and the search is unsuccessful.

Thks

I have just that module in my Taranis 9D with OpenTX.

2.4G CC2500 NRF24L01 A7105 CTRF6936 4-IN-1 Multi-protocol STM32 TX Module With Antenna

selecting protocol 1 (the only marked as "FLYSKY") I am not able to bind the receiver 9x8Cv2.

In OpenTX I selected

ExtRF Module : PPM
Channel Range: CH1-8
PPM Frame 25.0 ms 300us -


Any suggestion ?


TIA

One "problem" with that module is we never know what firmware it ships with. The firmware supports (currently) 36 different major protocols, so not all of them are available on the rotary switch when using PPM.
To guarantee the ones you want are available, you need to build and flash the firmware yourself.
Details are here: https://www.rcgroups.com/forums/showthr ... -TX-Module.

I'm not sure exactly where openTx is at regarding this module, there is support for using the Multi serial protocol, but that may only be available in 2.2.1 pre-releases. If you have the Multi serial protocol working then you may select any of the protocols.
