Hi Mario.
What code are you trying to run on the ESP32?
Can you upload the ESP32 boards in the Boards Manager?
Regards,
Sara

Hi Sara
I am following the course of Esp32, for the connection with classic BT. I uploaded the file in the example and for a few days it worked fine. Then I wanted to add a second uart and I followed here: https://www.youtube.com/watch?v=GwShqW39jlE
It gave me error, then I took a new ESP32 with FW of the course, (without uart modification) and it worked well for about 4 days. since yesterday I have this problem also on this second card.
I have found some answers in Github but I don’t understand if they are suitable for this problem.
I hope you can help me.
Thanks
Mario

Hi Mario.
What ESP32 board are you using? Can you share a link to the board you’re using?
And what board are you selecting in the Boards menu?
Regards,
Sara

Hi Sara,

I am using ESP32 DEVKIT V1, I have two devices until last week they worked well,
from board manager I selected “DOIT ESP32 DEVKIT V1″, UPLOAD SPEED 115200,FLASCH FREQ.40MHZ.
What you mean ” Share a link to….”
Maybe I solved the problem, yesterday I spent the whole day with several tests.
Then, after reloading the ESP32 into the board manager, I can reconnect BT to my phone.
and my app (Mit inventor) works again.
Now I continue the tests if everything ok I will close the thread.
I’m glady if you have any other advice.
Thanks

Mario
