If misconfigure wifi credentials, can't connect to AP

[piersfinlayson]

If you misconfigure your wifi credentials via the captive portal - or your usual wifi network goes away - the otb-iot AP doesn't appear to support incoming connections (to update connection details). This is a bit sad.

Doesn't happen if you just misconfigure MQTT server - only if you get the AP (or presumably password) wrong.

[piersfinlayson]

The problem only occurs with an invalid configured AP (incorrect password, or uncontactable MQTT server are fine). It's because of this:
esp8266/Arduino#1661
Looks like I should run a timer when trying to connect, and if it fails (times out, maybe for 30s) I should then terminate the station connect and sit with the AP available for a while.

Would prefer better behaviour - don't advertise AP until it can actually be connected to (after station connect has failed). The code is a bit yucky though so pushing this out until I have time for a rework.

Going to close this - it's fine as is (30s can't connect, 4.5 minute you can). A reset to factory defaults would fix anyway.
