tasks competing for resource??

[well_tech]

well, I have verified all potential options and have not found any obvious issues with memory etc., lets see how will it work. My guess is that there were too may code marked as IRAM_ATTR (including i2c driver), all IRAM was accupied (IDF showed 100% occupied IRAM in memory usage summary) and it probably caused some discrepancies. Many thanks for support!

On the S3, RAM is allocated to IRAM code as needed for the application. The amount of RAM dedicated to code ("IRAM") is not fixed; it is variably sized to just fit all the IRAM code and thus "IRAM" is always 100% filled.
