Hello, 
I receiver my new Beecore V2 frsky yesterday. But like everything, the frsky receiver is in fcc mode.  
Im using EU LBT on radio. Anyone have any idea how to flash this internal frsky receiver?

Which TX do you have?

Do you have D8 mode selectable on your TX. If so, it should bind. I am just going by what others have posted.

I have Taranis Q X7
And yup, D8 mode is selectable on radio, but cant bind :/ ( I found this post too )
I found somewhere it should support LBT with different fw, but cant fitnd it.

OKey after so much tests.. It will bind. But it takes minute! t bind. But after bind, I cant do nothing, because this thig have lost connection to radio in 99% time.
When Im connected via cable to betaflight. Sometimes I can se channel sending data, but for half a second.. So another bad part?

Gosh I never buld this tiny quad

If you TX is too close, you will lose signal. Try keep the TX and RX apart.

Yup I know this, but this isnt this case
