RN4678-V/RM100

The RN4678 module is a fully certified, Bluetooth v5.0
compliant (BR/EDR/LE) Dual mode module, available
for customers to easily add Dual mode Bluetooth
wireless capability to their products. The RN4678 is
built around Microchip’s IS1678 Bluetooth Dual mode
chip. Refer to Section 8.0 “Ordering Information”.
The RN4678 provides a convenient method for cable
replacement for smartphones or tablets for data
transfer and control based on the Bluetooth protocols.
Data transfer is achieved through the Bluetooth link by
sending or receiving data through SPP in Bluetooth
(BT) Classic mode and through Transparent UART in
the BLE mode. The ASCII interface provides an easy
way to learn the operation and to integrate the module
with any microprocessor or microcontroller (MCU) with
a UART interface.
