Aug 18, 2021 · No idea why it works with ESP-wroom-32D and desn't work with ESP32-wroom-32 though. Build the project and flash it to the board, then run monitor tool to view serial output: (Replace PORT with the name of the serial port to use. Create a BLE server that, once we receive a connection, will send periodic notifications. As soon as the ESP is up, you can use any BLE software (like BLE Scanner or nRF Connect) to test the BLE server. * Once The BLE code is now part of the ESP32 Arduino core, making it automatically available to any Arduino ESP32 project without the need for manual import. Thanks for reporting this. This example demonstrates how to create a vendor client model in Provisioner, and the vendor server example demonstrates how to create a vendor server model in an unprovisioned device.
