描述

I use echo example to set our BLE module as peripheral and use "nRF Connect" App of Nexus 7 2013 and iPhone 6 to connect the BLE module.

I can rapid connect it successfully firstly, but the 2nd connection will be stuck when I try connect it again after I disconnect the first connection.

There are no any log, just connection stuck unless I use ctrl+c to interrupt and then reset the "echo example".

研究方向
Investigate the disconnection handling in the bleno echo example. Compare the first successful connection with the stuck second connection. Check if there are any leftover state or event listeners after disconnecting. Add logging to trace the flow. Look at bleno's source code, especially the onDisconnect callback and any internal state management. Possibly a race condition or missing cleanup in the BLE stack.
