Stop client.connect() from blocking #67

Closed bobemoe closed 2 years ago

bobemoe commented 2 years ago

I'm trying to make my code more robust on an unreliable internet connection.

If the wifi is connected but the internet is not available, client.connect() can block for 15 seconds.

Is it possible to set a custom timeout? Similar to what was done here https://github.com/espressif/arduino-esp32/pull/2606

Or use a callback maybe so other code can continue to execute?

AT firmware doesn't support timeout for AT+CIPSTART and no other command can be run until the current AT command finishes. the library must wait for the response to the AT command.

Damn! Well, thanks for confirming.
