Setting up Bluetoot dongle

Technical Support for Routers

Hi there, I’m trying to set a Bluetooth dongle on a x750, I followed this doc [OpenWrt Wiki] USB Bluetooth support.

All seems good as the dongle is up

root@GL-X750:~# hciconfig
hci0:	Type: Primary  Bus: USB
	BD Address: E8:48:B8:C8:20:00  ACL MTU: 1021:6  SCO MTU: 255:12
	DOWN 
	RX bytes:1323 acl:0 sco:0 events:80 errors:0
	TX bytes:1130 acl:0 sco:0 commands:79 errors:0

root@GL-X750:~# hciconfig hci0 up

root@GL-X750:~# hciconfig
hci0:	Type: Primary  Bus: USB
	BD Address: E8:48:B8:C8:20:00  ACL MTU: 1021:6  SCO MTU: 255:12
	UP RUNNING 
	RX bytes:1998 acl:0 sco:0 events:122 errors:0
	TX bytes:1858 acl:0 sco:0 commands:121 errors:0

But when I try to config a Beacon nothing happens, the weird thing is a simple scan doesn’t show anything…

root@GL-X750:~hcitool -i hci0 scan
Scanning ...
root@GL-X750:

I’m pretty sure there are bluetooth devices around and that the dongle works as I checked using the same dongle in a PC

Furthermore, bluetoothctl does not seem to work as it can’t register or even the contoller

root@GL-X750:~# bluetoothctl
[bluetooth]# nnect to bluetoothd...
[bluetooth]# devices
No default controller available
[bluetooth]# power on
No default controller available
[bluetooth]#

Am I missing something here?

Thank you in advance

Well, at the end the problem is x750V2 (or the firmware) does not support Bluetooth 5 dongles.

I plugged a v4 dongle and everything works fine
