try this"

change the value of the line in recalbox.conf:
controllers.bluetooth.ertm=1
to
controllers.bluetooth.ertm=0

not tested.

hello, I have same problem...

Tutorial from Your link for me was hard and I've done this for other way.
I edit /etc/modprobe.d/bluetooth.conf file with help of Filezilla FTP.
I try also PuTTy by logging and use this tutorial https://recalbox.gitbook.io/documentation/tutorials/controllers/configuration-test/manually-connect-a-bluetooth-control.

Unfortunately no results.
