Hi. I'm working on a weather station project and it uses the ESP32's RTC memory. I added a function ( rtcmem.saveSession() ) that dumps the content of the RTC memory (as a string) and writes it to a file when the node is about to go to deep sleep. Then, upon startup, if a crash was detected, I can u...

I'm trying to add a function to the uos module which should create an empty file on my ESP32. Something like this: STATIC mp_obj_t test() { mp_int_t ret_val; printf("attempting to create file \"test.txt\"\n"); FILE* file; file = fopen("test.txt", "w"); if(file == NULL){ printf("file pointer is null\...

I have a boot.py file that looks like this: import machine print("Hello World!") machine.soft_reset() My ESP32 does not want to soft reboot. Basically, nothing happens. The "Hello Worl...

I decided to add an extra line that unmounts the filesystem before deep sleep. def goToSleep(reason="OK"): global netman, PowerManagement, rtc, runtime_...

I started writing the code in Arduino IDE however I decided to switch to MicroPython since I like Python a lot more than C++ and it allows me to implement some more complicated features easier. I finished writing the code for the project (it s...
