Crashing After Completing WPS Operation

[cferrarini]

Congratulations for the project, I am working on a free DDNS device with ESP01, and it would be great to incorporate the WPS button functionality.

After successfully compiling and uploading the sketch, the ESP01, it prompts to connect to AP and enters an exception loop with a stack, but if I turn off the Wi-Fi Router it stops this stack loop. The Telnet Server does not seem to start. Why am I getting this?

Arduino IDE Console when uploading:
O sketch usa 287.546 bytes (66%) de espaço de armazenamento para programas. O máximo são 434.160 bytes.
Variáveis globais usam 33.848 bytes (41%) de memória dinâmica, deixando 48.072 bytes para variáveis locais. O máximo são 81.920 bytes.
Uploading 291696 bytes from to flash at 0x00000000

Serial Monitor output:
Could not connect to WiFi. state='1'
Please press WPS button on your router, until mode is indicated.
next press the ESP module WPS button, router WPS timeout = 2 minutes
WPS button pressed
WPS config start
WPS finished. Connected successfull to SSID 'wi-fi2'

Hello cferrarini,
it may be your development environment.
I am using Arduino version 1.6.12 and the ESP8266 support version 2.3,
see ESP8266 Arduino support

I have a more detailed Telnet server project documentation here.
Regards, Rudolf

Hello Rudolf, Thanks for the the repply. Updated the IDE to 1.8.1 and the esp board drivers to 2.3. But now it shows only some gibberish characters on the monitor. It doesn´t even start the wps routine. Still trying to find what is wrong. Best Regards Celso 2017-03-02 2:03 GMT-03:00 rudi48 <[email protected]>:
