Creating BLE GATT Server (UART Service) on Raspberry Pi

Posted on March 4, 2019 by max

In this post, I will create BLE GATT server on Raspberry Pi 3 using BlueZ dbus interface with Python. I will reuse BlueZ example code as much as possible. As an example of GATT service, I’ll create UART service (a.k.a. Nordic UART Service/NUS [1] ), so that I can test it with Nordic’s smartphone app… Continue reading “Creating BLE GATT Server (UART Service) on Raspberry Pi” →
