I need Bluetooth documentation

Duo
1

Hi guys,

I’m trying to use the BLE module 01, and there isn’t much documentation on the subject.

The bluetoothctl tool isn’t working.

This issue was addressed a few months ago: Milk-V Duo-s basic bluetooth issue

I followed the steps provided in that discussion to get the service up and running, and it worked, but I can’t pair the device…

I understand that plugins are loaded from /usr/lib/bluetooth/plugins, but that path does not exist.

I also tried configuring the module by using hcitool -i hci0 cmd, but this process is somewhat cumbersome, is there any documentation for hci commands for this particular BLE module?

I appreciate any help with this issue.

Thread update.

Upgrade from SDK V1 to V2. The bluetoothctl issue is fixed with this SDK.

Just run it.

/usr/bin/hciattach -s 1500000 /dev/ttyS4 any 1500000 flow nosleep

and then bluettoothctl will work correctly

[root@milkv-duo]~# bluetoothctl 
[bluetooth]# hci0 new_settings: powered bondable ssp br/edr le secure-conn 
[bluetooth]# Agent registered
[bluetooth]# [CHG] Controller 0B:3B:22:AC:88:20 Pairable: yes
