What is meant by the "Transparent UART" function in connection with BLE? I have found this expression for the Dual BT Chip RF 4677. The Datasheet say's:
It supports GAP, SDP, SPP, and GATT profiles. Data is transferred over the Bluetooth link by sending/receiving data via transparent UART mode, making it easy to integrate with any processor or Microcontroller with a UART interface. Configuration is made easy using a ASCII commands via UART. Windows® based GUI, or PIC MCU configuration driver are also used to access configuration settings over UART.
