所以现在使用新的bluetoothctl工具来处理。可以使用此工具设置 gatt 表,如下所示:-
#bluetoothctl
[bluetoothctl] menu gatt
[bluetoothctl] register-service 0xFFFF # (Choose yes when asked if primary service)
[bluetoothctl] register-characteristic 0xAAAA read # (Select a value of 1 when prompted)
[bluetoothctl] register-characteristic 0xBBBB read,write # (Select a value of 0 when prompted)
[bluetoothctl] register-characteristic 0xCCCC read # (Select a value of 2 when prompted)
[bluetoothctl] register-application # (This commits the services/characteristics and registers the profile)
[bluetoothctl] back
[bluetoothctl] advertise on
我已经尝试了一些服务/特性组合,并且能够让它工作。GAP (0x1800) 和 GATT (0x1801) 服务默认可用,并且在您做广告时将成为 GATT 表的一部分。您还可以使用以下命令查看可用服务:-
[bluetoothctl] show
