Hi,

How to detect if some pin is short-circuited? I tried to google `esp idf short circuit` but got nothing useful. Could you please give me some guidance? documents, links, etc.

Thank you

I would like to play audio via BLE from android app to a esp32 board. How can I do that?
thanks

之前完全没接触过硬件方面，一头雾水。求指教。

现在是我有一个android app，有一块esp32板子上面有喇叭，板子刷了a2dp_sink例子的固件。如果用bluetooth 和板子pair之后，可以播放音乐。
现在要求不用bluetooth，而是用ble连接，然后播放音乐，请问可以实现吗？求指点迷津，谢谢。
