Unable to connect with Platform I/O espressif8266@4.1.0 (Arduino Core v3.1) #291

Closed Johboh closed 1 year ago

Hi! I have not investigated this further and will provide more debug printouts, but everything works fine when using version 2.5.0 of this library and espressif8266@4.0.1 which uses Arduio Core 3.0.2. But after upgrading to espressif8266@4.1.0 which uses Arduino Core 3.1.1, I'm unable to connect to the MQTT server with the error message LWMQTT_MISSING_OR_WRONG_PACKET = -9.

This is mostly a heads-up that if anyone else is experience connection issues when using Platform I/O and espressif8266@4.1.0, try with espressif8266@4.0.1 until this issue has been solved (if the issue is in this library or in Arduino Core, we don't know yet).

Same as #292

There is a solution in #292. Changing delay(0) to delay(1) fixes the issue with latest arduino core.

Closing in favour of #292.
