DEVO10 : Problem with MM... was created by a.steroid
Hello all ! :)
I've just installed multimodule in my Devo 10 (white) (with A7105-500, nRF24L01+PA+LNA, CC2500 + PA + LNA) like in the famous tuto video (thx for all SeBy DocKy !).

Tested with DeviationTx nightly deviation-devo10-v4.0.1-c3007aa and stable.

Now, when I turn the knob (AUX4 ou AUX5) then Tx very often power off or restart.
I've seen on video comments that someone already have this problem...

I had open a bug issue ( www.deviationtx.com/mantisbt/view.php?id=631 ) and i will try to report photos tomorrow but if someone here had already face to this problem, please tell me ! :)

Sorry for my bad english...

Try the Nightly Build of 2015-06-08 with deviation-devo10-v4.0.1-548bbf5.dfu

I have the above mentioned build on my DEVO 10, with Multi-Module populated the same as yours, and have no power-down issues with AUX4 & AUX5 being repeatedly twisted to each limit. If you still get the problem, then you can rule out the .dfu as the problem. Did you also calibrate the AUX 4 & 5 knobs when calibrating the sticks during the transmitter configuration process?

DEVO 10 - Multi-module with nRF24L01 +PA +LNA, A7105 +PA, & CC2500 +PA +LNA transceivers.
Nightly Build: v4.0.1-548bbf5 (6/9/2015)

After some investigations, I think i found the problem !
I drill antenna hole between knob and main antenna for the two side:



I think the problem is antenna GND can be join to knob GND (through the little piece of steel indicate AUX4).

What do you think about it ?

I've done some correction for isolate the antenna gnd, and it semms to be ok ! :silly:



It seems to me that the new devo 10 (white) has bigger steel stick for knobs so this problem will perhaps be encoutered in the future.
