METR PRO + Firefly Nano remote

Hi im just wondering if its possible to use the METR Pro and the firefly Nano remote together i have the Flipsky 6.6 Duel FESC which has 2 uart ports can i plug the Blutooth module into the slave side and the remote into the master side?

Yes you can.

thanks wasnt sure if it would damage the vesc or even work

Could there be made a piece of code for the receiver of the firefly, which does split uart, like the usplit but integrated in the receiver?
