因此，现在可以使用新的 工具进行处理。可以使用此工具按以下方式设置gatt表：-
#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
我已经尝试了几种服务/功能组合，并且能够使其正常工作。默认情况下，GAP（0x1800）和GATT（0x1801）服务可用，并且在您做广告时将成为GATT表的一部分。您也可以使用以下命令查看可用的服务：
[bluetoothctl] show
