Hi man, this is EmersonBH from Brazil, and I would like to thank you very much for this very interesting playlist about ESP32. I would like to inform you that this playlist is responsible for making ESP32 increasingly relevant to my electronic projects based on ESP32 from now on.

What kind of gloves are you wearing? Those seem to be useful to avoid burns

Hello,
your series on esp32 is really great and im benefiting from it very much.

I have one question, that is, does your use of the voltage regulator relate to the following error?
(brownout detector was triggered)
Im having this error as Im trying to use BLE in my code. I can programme the chip using the FTDI programmer through arduino without the need for any voltage regulator, but that's only for normal codes (i.e GPIO simple use). However, one I try to use BLE, I get that error which I suspect to be related to powering issues.

I appreciate your help
Best regards

Hi. When developing ESP32 applications using the Arduino IDE are the dual cpu's fully taken advantage of as they can be using the SDK? Can we expect to support WiFI, a Web Server, ajax, and an application reading sensors etc, without random WDT timeouts? Thanks for all you do!

Hi! Thanks for the tutorials.
I've got a question.
What's the minimum current that is needed for the 3V3 pin?

Heloo, can i control webasto thermo v with ESP32? To Cam or k port?

Why do you use putty? The arduino app has a serial console already builtin, it does saves a lots of clicks.

Dear Sir,

I try to upload program to ESP32, but error message show about that

How to fix this problem.


Thank you.
