BlueZ网关通知

Question

我正在使用BlueZ库gatttool，但是当我运行下面提到的gatttool命令时，它会给我无尽的通知。是否有任何方法，它只发出一次通知，然后退出命令？

命令：

gatttool -b BC:6A:29:AC:02:57 –char-write-req -a 0x2E -n 0100 –listen;

产出如下：

Characteristic value/descriptor: 00
Characteristic value/descriptor: 01
Characteristic value was written successfully
Notification handle = 0x002d value: 01 06 40
Notification handle = 0x002d value: 01 05 40
Notification handle = 0x002d value: 01 06 40
Notification handle = 0x002d value: 01 06 44
Notification handle = 0x002d value: 01 05 41
Notification handle = 0x002d value: 01 06 41
....endless notifications..... I just need once

只需在没有--listen选项的情况下运行它。

gatttool -b BC:6A:29:AC:02:57 –char-write-req -a 0x2E -n 0100
