Disconect and not useable on ESP32-S2

[dzungpv]

I run a project on ESP32-S2, it has single core 2MB PSRAM, frequently disconnect reason 7, It more powerful than ESP8266 but I dont know why. The project running Homekit stack, Async Web-sever and espMqttClient. I check the ram it is free 92% all the time.

Which S2 board?
Do yo have access to the broker logs?

All due respect for your problem, but the solution is to be found outside this library. There is no platform-specific code inside the library. This doesn't mean I'm not on the lookout for the root cause.

I fixed and tested with this PR, it is fine now.
#139

Before I merge, let me test me a dual core ESP32 too.
People that specify a specific core won't be affected but I seldomly do that myself.

With Christmas in a few days, activitiy will be low. So this probably has to wait a few days.

Yes, but you can see the code, it detect number of core of the ESP32 chip with https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-reference/system/misc_system_api.html#_CPPv415esp_chip_info_t and same with https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/misc_system_api.html#_CPPv415esp_chip_info_t and c3 etc. If chip more than 2 core, the same behavior. I have ESP32 dual core running too.

But TLS MQTT is the same, it is not fix with my PR, it is somethings else, only normal mqtt work for ESP32S2 chip. May be my app too heavy for the 1 core chip.
