I am currently testing the ESP32 BLE in combination with Blynk (using the Android app) and I am really satisfied, this is the most stable Bluetooth implementation of Blynk I realised so far.
There is one important missing feature however: there is no way to define the BLE device name, it is fixed to “Blynk”. Can you add a parameter in the library to set the BLE device name? I want to use it in workshops with 10’s of ESP32 devices, so they really need a different name.
