ESP8266 Wifi Diagnostics explanation

I am programming an ESP8266 via theArduino IDE on a Windows 10 PC. I can turn WiFi diagnostics on with Serial.setDebugOutput(true); - so now I get a bunch of stuff like:
Access point started
scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 2
cnt
connected with XXXXXXX, channel 11
dhcp client start...
chg_B1:-40
- the meaning of some of it is obvious - but not all of it. So I'd like to ask if it is explained anywhere. I've spent a long time not finding it.
Related to that - I'm trying to get a system to start an access point so I can connect to it and tell it my WiFi credentials, and then it will disconnect the AP and connect to the network using those credentials.
I want to leave the Access Point up long enough to tell the user that the credentials were fine and they can now re-connect via the usual WiFi network.
I can get each element working but not all elements together, reliably.
I know about WiFiManager, but that library is vast. Is there any other resource I've missed which might help?
Thanks,
Chris

Chris,
You can always look at the diag implementation in the source code and in examples ... perhaps igrr documented the output a bit better....
On my linux system:
Code: Select all ~/.arduino15 $ grep -r "setDebugOutput"
packages/esp8266/hardware/esp8266/2.3.0-rc2/doc/reference.md:By default the diagnostic output from WiFi libraries is disabled when you call `Serial.begin`. To enable debug output again, call `Serial.setDebugOutput(true)`. To redirect debug output to `Serial1` instead, call `Serial1.setDebugOutput(true)`.
packages/esp8266/hardware/esp8266/2.3.0-rc2/doc/reference.md:You also need to use `Serial.setDebugOutput(true)` to enable output from `printf()` function.
