The ESP-WROOM-32 chip is used. In common case (external 3.3V is used on GPIO12 in the circuit) flashing is not possible, the flash is blocked. But, in case I connect GPIO12 temporarily to GND during flashing and also during device's start, everything is OK. So what is the result for me please?

Setting flash voltage
Hi,
I have GPIO12 pin used as output with pernament 3.3V on it in my own circuit. What flash voltage should I set for trouble-free flashing and sketch running? Should I set espefuse.py set_flash_voltage 3.3V or OFF or deal with it in another way
?

Classic Bluetooth password verification
Hi!
Is there any way to implement a verification by password for classic Bluetooth connection / communication when programming in Arduino?

Re: ESP-Prog with Arduino IDE :?:
OK, I don't see any problem in using Arduino IDE or wiring ESP-Prog to my board. But I hesitate e.g. what programmer should be set in Arduino IDE or if anything else for ESP-Prog has to be set.

ESP32 sleep while...
Hi, I have a question regarding the ESP energy saving during a long lasting process. Consider that ESP32 would use IO pin to control a relay, e.g. for the light bulb switch on. The relay would be active for about 1 hour. Is there any possibility to change pin state and then give ESP to sleep? If yes...

Sleeping alternated with bluetooth listening
I use ESP equipped with external RTC. I would like to make ESP asleep and wake-up only by RTC alarm in specific times. But simultaneously I would like to use BT or BLE to deliver the alarm times by user, so no kind of pernament sleeping is not possible in such case. So I think about sleeping of ESP ...
