To Reproduce Steps to reproduce the behavior:

  1. App connects WiFi(internet) to connect IoT
  2. App changes the WiFi to a device's AccessPoint (not internet)
  3. App setup a TCP socket to the device in AccessPoint
  4. device's AccessPoint breakdown and App auto reconnect the WiFi (internet)
  5. IoT will auto be changed to disconnect、reconnect、error or other states in SDK
  6. It will sometimes be crashed in AWSIoTMQTTClient openStreams

Which AWS service(s) are affected? AWS IoT
