Re: Is writing unique Id directly in esp32 using esptool.py possible ??

If I understand you right the 'Non-volatile storage library NVS' could be a good solution I tried it once to store a name string of sound-light installations, and it worked fine ( I did #include <Preferences.h> to make it easy) If nvs entry size (32bytes, I think) is too small you can use multiple e...

Re: ESP32 reboots with WiFi scripts.

My ESP32 hangs up everytime I load a script needing WiFi.
Maybe you just have a problem with your power supply, and the ESP browns out?
Did you put a capacitor between +Vcc and Gnd?

Re: how to restart bluetooth after light sleep

Sorry, forgot to mention that I *did* try to call BLUEtoothSerial.end(); before going light sleep. This step seems logical to me, but if(BLUEtoothSerial.hasClient()) the end() function crashes and reboots. (Maybe I must disable the connection first? I do not now how to do that from the ESP side) sti...

ESP32 is a wonderful beast, but sometimes I don't get it... For a projet that has emerged out of an old Arduino project i need a lot of gpio outputs. The project uses Arduino IDE I have tried to simplify the code so you can spot why it is not working The pins to test are stored in an array they have...
