So how do I find the right service then? I thought looking up the UUID via this app would get me my desired service/value. Is there a way to connect to my device via the name and let the ESP display all the available services and characteristics from said device? Then I would be able to pick the cor...

Hi, thanks for testing my code. Unfortunatly whatever I do this specific code won't work on my devices. I did some research and changed this part: class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks { /** * Called for each advertising BLE server. */ void onResult(BLEAdvertisedDevi...

The code was posted above as a link. Here is the complete code I uploaded to the ESP32: /** * A BLE client example that is rich in capabilities. */ #include "BLEDevice.h" //#include "BLEScan.h" // The remote service we wish to connect to. static BLEUUID serviceUUID("000018ff-5348-494d-414e-4f5f424c4...

If it helps, I was able to form a connection and communicate with the ESP32 via this Bluetooth Terminal App. Does anyone know what the backtrace means or can point to a different solution for my issue?
Thanks in advance,

Thank you for your quick replies. This is the result I am getting with the ESP exception decoder: Decoding stack results 0x40090c38: invoke_abort at /Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/esp32/panic.c line 140 0x40090e3b: abort at /Users/ficeto/Desktop/ESP32/ESP32/esp-idf-publi...

@ESP_Sprite
I am not using the ESP IDF but the Arduino IDE. Unfortunatly I was not able to get the ESP IDF started on my PC. Is there a similar way for the Ardunio IDE to see where the crash happens?

@chegewara
Thanks for the explanation. This was helpful.

Hey folks, I am trying to connect to a BLE device (Shimano SC-E8000) . For now I just want to read a few characteristics to ensure I have a stable connection. Unfortunatly I can´t get it right. Here is what I did: Using the nRF Connect App I got the Service and characteristic I want to read out. I a...
