oh ok. I didn't know that. Thank you for your answer. Any plan to support the built-in bluetooth of rp3 in the future versions?

I have just installed recalbox v4.0.0 beta 5 on my rp3. Everyting works fine until I try to connect rp3 with my 8bitdo zero. The rp3 found no controller (I started the controller already (using Start+R)) .
here are some logs:

lsmod

I try to enable bluetooth using rfkill, but don't know how to install rfkill on arch (I only have some exp with ubuntu).

Anyone know how to enable bluetooth on my rp3 running recalbox?

Thanks
