Help with Bluetooth telemetry dropping

Hi, I’m pretty new to all of this so might be missing something obvious.
I’m using a Matek f765 board with dragon link v3 on a tx16s radio.

I can get a telemetry stream to Mission Planner via Bluetooth on the workbench.
It doesn’t always connect first try but once connected it has been solid.
I have an issue with actually flying though. Shortly after taking off the computer will disconnect with the Bluetooth connection and fail to reconnect.

Has anyone had this same issue, or should I just abandon the bluetooth? Is it possible to just hardwire it to the dragon link tx USB connection?

Thank you,
