First of all, the issue im facing is that the sensor occasionally reads the maximum value for a signed 32-bit integer which indicates an error. Ive tried altering the delay - Even to 5000 but that doesnt seem to be the case. Nevertheless, when i removed the WiFi connecting code (CHECK BELOW), it worked without any issues - even in 500s read rate. I acknowledge that i am allocating enough memory for the task and etc but i dont seem to understand this behaviour. I would love for some help.
