I tried running an example sketch from Module 2, Unit 6 using a TTGO LoRa board, but with the interrupt and LED pins re-assigned to #12 and #13 respectively. After initially operating as expected the board now continuously outputs a serial stream of internal status details and will not accept a new download.
Have I caused the ESP32 to enter some kind of debug mode by pulling the assigned GPIO pins high or low during startup? Advice on how to exit this mode would be much appreciated.
After being off for several hours, the TTGO LoRa board powered up without sending diagnostic info (?) from the serial port and now accepts downloads again.
Therefore not bricked but still worrying.
Thanks for getting back. On power up diagnostic type sentences are sent to the serial monitor but once triggered everything conforms to your tutorial. No problems.
BTW, Great well written material, that’s helping to keep me sane during look down.
I’m glad that everything is working fine now and that you enjoy our materials.
We’ve also been publishing new projects more frequently, so that our readers have more new content to experiment.
I’ll mark this question as resolved.
If you need further help, you just need to post a new question in our forum.
