ESP8266 Stops Working if I don't provide Wifi during specifc step

Question

To test the WiFi connection I'm sharing the WiFi of my cellphone.

If I stop the WiFi sharing during the command below, the ESP8266 stops working. It only works if I do a hardware reset.

If I don't stop the WiFi it works normally.

 if(client->POST(urlCal, host, payload))
 { RetornoPost = client->getResponseBody(); }

• HTTPS Redirect (Version 2.0)
• ESP8266 library version 2.4.2

Does anyone know why ESP8266 stops working?

Answer 1

If by "stops working" you mean it doesn't do whatever follows the client->POST method invocation, then your interpretation is correct and you could have found my very same information if you had read the open issues on the library before submitting your own.

If I were the author of the library I would be upset by such behavior.

• Bruno Yuzo: Now it is working! In tests the version "2.5.0-beta2" solves this issue!
• Bruno Yuzo: Sorry for the wrong information, but unfortunately, the error keeps occurring with "2.5.0-beta2". Sometimes ESP8826 restart when there is an error and is OK. But other times ESP88266 breaks, and I have to do a Hardware Reset.
• Bruno Yuzo: ESP8266 library version 2.6.3, and watchdog to wait the resposnse, solve this error.
