I had to buy a new wifi transmitter after losing video feed with the original transmitter even though all the other telemetry features worked. I installed the new transmitter in the Phantom and then tried to bind it with the wifi extender using the QR code that the new transmitter came with. I can not get it to work. Is the QR code that came with the new transmitter on a separate label that was provided the correct one to use and is that the only thing I should have to do? Frustrated in Texas!
