The server or the client uses the transparent UART TX characteristic data transmission. After enabling the Client Characteristic Configuration Descriptor (CCCD) of the transparent UART TX characteristic, the server sends data to the client using the notify property. The client can also send data to the server using the write/write without response properties.
