USER’S GUIDE
Chapter 1. Introduction
1.1 OVERVIEW
Microchip RN4677 Certified Bluetooth Dual Mode module supports both Bluetooth
Classic and Bluetooth Low Energy (BLE) communication. Under Bluetooth Classic,
RN4677 implements standard Serial Port Profile (SPP) that supports serial data
transfer between two Bluetooth Classic devices.
In addition to SPP for Bluetooth Classic connectivity, the RN4677 introduces a private
Generic Attribute Profile (GATT) service for serial data transfer between two BLE
devices. This BLE data streaming service provided in the RN4677 is named
“Transparent UART”. Therefore, the RN4677 is a Dual mode Bluetooth module, which
supports both Bluetooth Classic and BLE serial data connectivity.
RN4677 module is developed on top of Microchip's IS1677 Bluetooth IC. The primary
difference between RN4677 firmware and the standard firmware in the IS1677 is that
the RN4677 provides the control interface based on ASCII commands. The command
interface on RN4677 is very similar to that of RN41/42/52/4020, providing an easy
migration path for customers who are currently using RN modules.
Interactive ASCII commands enable the RN4677 to be configured without complex and
customer configuration tools. Like the other RN modules, the RN4677 also supports
master/central capability, actively scanning for other connectable devices instead of
waiting for incoming connection requests.
1.2 COMMAND MODE VS. DATA MODE
RN4677 operates in two modes: Data mode (default) and Command mode. When
RN4677 is connected to another device and in Data mode, RN4677 acts as a data pipe:
anything received from UART is passed to the connected peer device through SPP if
connected to a Bluetooth Classic device, or via a private GATT service if connected to
a BLE device. When data is received from the peer device from SPP for Bluetooth
Classic or UART Transparent for BLE, such data outputs directly to UART.
RN4677 is configured or controlled, or both by setting it into Command mode and
executing ASCII commands over UART. All configuration changes made by Set
commands remain in Non-Volatile Memory (NVM) and survive the power cycle. Any
configuration changes must take effect after a reboot. All Action commands take effect
immediately, but have no effect after power cycling.
