Problem in short is that once a WiFi connection is dropped, eg by disabling and renabling your WiFi hotspot, the Photon does not reconnect again until one reboots the Photon. This is a real problem in the field!
This is very similar, if not one and the same, as the following issues:
@mhazley as described here [v0.4.8-rc1 / v0.4.9] WiFi Reconnection Issue and here Failures on handling WiFi reconnects ( v0.4.5 / v0.4.6 )
There are others reporting related issues.
Am running v0.5.3.rc, ie the latest public release.
Is there a recommended way to overcome this problem in application code?
