ble_app_uart例程增加一个按键事件 - 无事件回调产生是什么原因呢？
本帖最后由 reliXQ 于 2018-11-14 12:22 编辑本人才疏学浅 刚接触52832一个按键回调都调不出来再此请教大神帮忙解答一下疑惑
程序文件片段:

遗憾的是 我按下按键后并没有触发任何回调函数.没有任何printf打印
再次求教大神是哪里的问题？
advertising_buttons_configure() 这个配置错了，我们教程《协议栈下按键的使用》有详细讲怎么配置的

文档中讲到的:
初始化板级设备 BSP.
初始化板级支持包， 实现按键反应和状态指示。 同时按键反应后分配给回调事件。
注意： 在你使用这个功能前， 你必须启用如下的模块：
Application Timer for LED support
GPIOTE Handler for button support //请问这个是怎么配置的
UART module for UART support

该函数里有个app_button_init 函数，里面初始化了GPIOE功能 已解决PDF教程很仔细多谢！
