By adding gc.collect() at the end of datacb causes an immediate "Guru Mediation" crash. It reads and prints first subscribed message OK and then crashes when it calls gc.collect(). published - 1 ('subscribed - ', ('ESP32_DHT22_Sen', 'temp_humidity', 'OFF')) Guru Meditation Error of type LoadProhibit...

Hello Borislav, Have been testing simple mqtt client publish and subscribe on Lolin esp32 Pro with SPI ram. Board crashes repeatedly with "Guru Meditation Error" at random intervals generally within 10-15 minutes. Crash report: Guru Meditation Error of type LoadProhibited occurred on core 1. Excepti...

Thanks Borislav for detailed explanation.

I have it working with clarified mandatory name and server arguments.

Will continue experimenting with other options.

Best Regards

Hello Boris, Sorry to pester you on Christmas eve, but its a good free time to play with micropython. I have started playing with various micropython mqtt options on the esp32. I'm having difficulty in understanding your version of API call for establishing a connection with a local wifi network mos...

Hvala Borislav,

Little bit of beer money added to your paypal account for the festive season.

At the moment tried couple of boards with same results where clock gains about half an hour in less than 6 hour period. Board is VCC-GND-407VET6 MINI. N...

Have reduced heap allocation of 125K to 80K and is working for now.

Sorry to pester you with noob questions Boris. I have just started playing with your esp32 Micropython port and will take a while to understand BUILD menuconfig options. Since my Wrover kit came with Wroom module installed and I tried to build firmware with external SPI RAM which didn't work for obv...

Thanks Boris That's it, trap for uninitiated. Wrover kit with wroom module??? I have stand alone wrover modules that I can replace the wroom. Looks like solder pad footprint is in place for wrover, I hope that it doesn't need any other support components. Now for a bit of unsoldering fun without lif...
