Binding issues with nRF24L01+ was created by hogan
I installed this module www.banggood.com/DEVO-Transmitter-Tuner-...ys-V922-p-89812.html
in my devo 7e. Modified the tx file in notepad++. Already have the A7105 ( running great). Followed daryoons webpage and when I attempted to bind it with the FBL70, the servos did their typical thing in resetting and then nothing. The light on the heli was rapidly flashing but couldn't do anything.
My V911's, MSRx, and Ladybird still bind and fly.
any ideas?

Please post your deviation build revision, your model file, hardware.ini file.

Modules are no longer enabled in the tx.ini file.

Thanks.

don't see anything obvious wrong with your tx.ini or your model file. Can you take pictures of your module install to ensure it is wired properly?

second pic is both A7105 module and nRF module together. The PCB on the Tx


the wires are heatshrinked to the module so a photo would not be useful but it is identical to the photo in hack mod page.

TMS yellow wire goes to A7105 module, TCK yellow wire goes to nRF module.
VDD has both wires to the modules including a pink from the MISO from the nRF

MISO of the nRF module should be connected to MISO of the CYRF module.
CE of the nRF module should be connected to VDD.

I think they are.
The VCC(red wire) and CE (pink) wire are together with the red 3.3v from the A7105. There are 3 wire going to the VDD.
The MISO on the nRF is attached to the 4th pin from left, well from the right as well.

I just double checked the wires and they seem to be correct. I knew the A7105 module went too easy!

Got them working.
1- I put a small piece of electric tape between each of the wires going to the Tx board.
2- The FBL70's were not on the HISKY protocol on the Tx. One was on PPM and the other was on NONE.
3- When experimenting, make sure the main motor is UNPLUGED! Found out the hard way that the throttle was reversed and up she went like a scared rabbit. Nearly took my head off!!

All I have left is to figure it out to work with Phoenix and will be back down to 1 Tx!
Thanks to all who tried to help.
