2 Transparent UART

The RNBD451 module introduces a proprietary GATT service known as “Transparent UART”. This service streamlines the transfer of serial data over Bluetooth Low Energy devices. The RNBD451's Transparent UART functionality enables the seamless transmission of serial data from its UART interface via a Bluetooth Low Energy connection, creating an end-to-end data pipe to communicate with another Bluetooth device, such as the RNBD451 module or smartphone.
