ESP32 Forum

I've been working through Kolban's videl (https://www.youtube.com/watch?v=-ttiPfm ... poUUE7QMOo) and everything appears to work OK, but I'm getting this strange output at make flash monitor:

This is the end of the make flash, then it just sits there waiting. If I hit anything on the keyboard, it appears that it is being forwarded to the ESP32 device. Ultimately, I do Ctrl+] to exit. I've tried it with several devices, and all have the same problem. I also tested to the device using Arduino IDE, and it works properly.

What does your application do? What should we expect to see on the output? If you are using ESP_LOG macros, then by default, the logging level is set to warning. If you are logging at DEBUG or VERBOSE, you would want to switch the flags to log at lower levels. It may be that the app is working perfectly and you haven't enabled enough log info for it to appear.

Well, until you poked me ("wake up, what's the code doing?"), I had just assumed it was doing a 'cout'. That, of course, would be wrong. I guess I took the video too literally where it says the debug level is just a personal preference, and had it running at a higher level.

Changing the log level to debug appears to work.

Being new to C++, Eclipse, and ESP32, guess I was just unexperienced and confused.

Thanks for the 'poke!'.

Poked awake by a Texan with an accent....sheesh.

At least my BBQ is better than yours.
