🌶️ - Bluetooth Low Energy Serial profile sample

Shows how to use the Serial Protocol Profile APIs included in the NanoFramework.Device.Bluetooth.

The sample allows a Bluetooth Terminal program to connect and send/receive text messages. There are a number of applications on both Android and IOS that will work.

The device should be seen as "nanoFrameworkSerial" when scanning for the device.

Send device 'help' to get information on what messages it will respond to.

This sample is a example of what you could do to provision your device with required data like wifi credentials, name etc.

The sample is located here.

Hardware requirements

A ESP32 device running a nanoFramework image with the Bluetooth enabled.

Currently there are 2 firmware images that support Bluetooth:-

  • ESP32_BLE_REV0
  • ESP32_BLE_REV3
