WiFi channel switching stops WiFi connectivity and is only recoverable by reboot (BUG)

Firmware
21

I have updated my findings in this issue:

The problem is still not resolved, 0.8.0-rc.2 doesn’t fix it.

Seems even worse than before, because even though I have

SYSTEM_MODE(MANUAL);
SYSTEM_THREAD(ENABLED);
The application is completely blocked when WiFi is lost.
WiFi connectivity handling still seems to be absolutely terrible.

I am getting unhappy about my choice of Particle as a platform for my products.
Is it too much to ask from an IOT platform that:

  • Losing WiFi does not completely block the system
  • Wifi disconnects and channel switches are handled correctly and when WiFi returns
  • it always reconnects
  • A TCP server ran by the device does not get into an unrecoverable error state when WiFi is bad or temporarily lost?

I have given you test code. I reported this bug over 6 months ago. I feel unheard and ignored.

Is it perhaps possible to add some system event hooks to handle WiFi disconnects?
I’m really trying to find a solution because I have a lot of customers affected by this. Why can’t someone at particle provide some example code that:

  • Handles WiFi connecting/disconnecting without blocking the main thread
  • Handles running a TCP server on the photon that in a robust way
