What is the expected behavior?

Fix bugs

What is the actual behavior?

1. In classic Bluetooth mode, the module will still have no data downstream, and the module will automatically recover, but the time is too long, which takes 1 to 2 minutes;
2. In WiFi mode, you can search the WiFi hotspot in the notebook, but you cannot connect it.
   It needs a little more refinement
   Bluetooth reconnection time optimization to less than 5 seconds is better, WiFi this problem please check why can be found but not normal connection, is the transmission protocol has been adjusted?
