If you issue "make monitor" or even "make flash monitor" then the internal ESP-IDF monitor is launched.

The scanner is very selective, it only found one estimote beacon that i have.
It completely ignore a beacon of a hm-10 and others that i detect but arent mine.

@bombix: In other words: You can forget about. There are enough well working alternatives around which surly blame the ESP32 for the fails. What setup do you have? What development board?

Here is some more information on all the glitches in conjunction with BLE I found so far. For me the ESP 32 would be a wrong choice currently.

Have you tried keeping a connection with a cell phone and sending the scan results to it?
Thanks for all the help.
