Hi, I'm working with the seeker dev Drone and I buy the Spektrum DSX 7-Channels transmiter to fly in manual mode. I follow the instructions to bind the transmitter to the DSMX Remote Receiver. The bind was complete, because I se the receiver turning on with the transmiter power button but When I go to Qgroundcontrol to calibrate the transmiter I keep getting a message to turn on the transmitter while I have the transmitter on.

Anyone Knows why is this happening?

@Ariel-Saez I already fix the problem, any case someone have the same problem, you need to update the SDK with the proper SKU version, in my case the /data/modalai/sku.txt show me  "MRB-D0003-1-V1-C7", and looking my modalai's bill, show I buy the MRB-D0003-2-V2-C7. Next I change my sku.txt with the right code: MRB-D0003-2-V2-C7,  then I update my voxl and fix everything.
