Don't trust the RSSI values, it is mostly complete nonsense

Well in fact - it doesn't even scan a single RadBeacon Dot, what do I expect....

@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 woul...

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

@heyinling: The question was about the capabilities of the ESP32 hardware (BLE part): There are some other chips available, which for instance are limited with respect to the number if unique iBeacons which can be received in a given timespan. I know about TI chips, which are limited to 20-25. What ...

Thanks @kolban. I'm also working with platform.io in an ESP8266 project, using Visual Studio Code as IDE. The same IDE is perfectly working (including symbol resolution, git support and kind of "intellisense") in the ESP-IDF world. Right now ESP-IDF is the bleeding edge in ESP32 development and the ...

You need to follow the installation rules provided here https://github.com/espressif/esp-idf Then take the /examples/bluetooth/gatt_client/ and copy my main.c into the main sub dir. Remove gatt_demo.c Run "make menuconfig" from the root of the project. After the proper configuration run "make flash"...

@jkhax0r: Yes, it seems, there is something rolling. Seems, this forum is pretty uninformative. I never got any substantial answer to valid questions here. But I opened an issue here: https://github.com/espressif/esp-idf/issues/421 Right now the RSSI bug is confirmed and fixed. Just waiting for the ...

Maybe code sharing helps to come behind: Here is the code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include "sdkconfig.h" #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "freertos/event_groups.h" #include "esp_system.h" #include "esp_wifi.h" #include "esp_event_...

I can confirm this mess. I'm using a Sparkfun ESP32Thing. RSSI values are sometimes complete nonsense, some industry standard iBeacons (like RadBeacons) are not recognized at all (or just occasionally). Here is my ESP32-IDF snippet and the results I'm receiving with it. Donald would finish with "Ver...
