@Turbine Thank you, I had this problem and your solution was spot on. Problem fixed.

Tried creating an overlay and changing it to; peripheral? /dts-v1/; /plugin/; / { compatible = "allwinner,sun8i-h2-plus", "allwinner,sun8i-h3"; fragment@0 { target = <&usb_otg>; __overlay__ { dr_mode = "peripheral"; }; }; };

some progress $ sudo rfcomm bind /dev/rfcomm0 41:BB:00:D0:D3:D8 && ls -l /dev/rfcomm* crw-rw---- 1 root dialout 216, 0 Jul 7 22:46 /dev/rfcomm0 but $ sudo hcitool info 41:BB:00:D0:D3:D8 Requesting information ... Can't create connection: Input/output error
