2.2 Transparent UART Connection and Data Transfer using Microchip Bluetooth Data App

To achieve bi-directional communication between the RNBD451 module and central device over the Bluetooth Low Energy link, use Microchip data service. The transparent UART service is instantiated as a primary service. The service UUID of the transparent UART Service is set to 49535343-FE7D-4AE5-8FA9-9FAFD205E455. The transparent UART service contains the following data characteristics:

  • Transparent UART Transmit (TX) Characteristics UUID – 49535343-1E4D-4BD9-BA61-23C647249616
  • Transparent UART Receive (RX) Characteristics UUID – 49535343-8841-43F4-A8D4-ECBE34729BB3
  • Transparent Control Point (TCP) – UUID 49535343-4C8A-39B3-2F49-511CFF073B7E
