Binding problem

Hello,

i like my Devo 7e very much. I use it with different models and different protocols.

I had some problems with the range mod and now i have soldered in the 8s upgrade module. Made a upgrade to the version 4.0.1.

I can bind my v911 and the A 7105 module. Also i can bind my QR Ladybird.

I cant bind to an OrangeRx Dsm2 receiver.

And i cant bind to my Merlin Pilot 500 with the J6Pro protocol. 6 month ago with 3.0.0 it has worked.

Didnt tried my AXN with the Spectrum receiver.

I have tried several settings without success.

Any ideas?

Tried it with and without fixed ID. No success.

After countless trys to bind the Pilot 500 (J6Pro) with my Devo 7e/8s upgrade module/Deviation 4.0.1 i have upgraded my second Devo 7e (everything is stock) to Deviation 4.0.1.

I tried to bind the Pilot 500 with this second 7e and it works with the first try.

So what can be wrong with my Devo 7e and the 8s upgrade module?

Any ideas?

Uwe

I get only 1.2V from MISO directly measured at the mainboard.

I get 3.2V from MISO at my stock Devo 7e directly measured at the mainboard.

Maybe this is the fault.

perhaps you damaged your original 7e when removing the original rf module? or when originally removing the diode?

Yes, this is possible! Or something with my A7105 is wrong which has burnt something at the 7e mainboard. I am lucky to have one working 7e to control my Walkera models.

So i have to decide if i buy a v911/v959 transmitter or buy a new A7105 module from Banggood.

I dont want to use my old A7105 again. I had issues with it from the beginning.

Dont want to burn my working 7e.

well i used both an A7105 and an NRF24L01+ module from banggood in my 7e and i have had no problems with them, so i would recommend them to you without issue
