4. Basic Applications
4.1 Recommended Circuitry
5. Functional Description
5.1 Role Description
Module Support Role: Slave.
The module slave can be connected with other models of our Bluetooth products to support transmissions.
5.1.1 Pragmatic
1. The module only supports slave mode
2. The broadcast switch configuration is on by default, and automatically enters the broadcasting state after power-up is
completed, otherwise the stop broadcasting device is undiscoverable.

3. After receiving the host connection request, establish Bluetooth connection and stop Bluetooth broadcasting.
4. Broadcast data configuration see 5.5 broadcast described.
5.2 Role Description
The module supports two power modes: low power mode, and wake-up mode.
5.2.1 Low Power Mode
The so-called low power mode means that the module enters into this mode to turn off the broadcast and disconnect.
Entering low power: PB4 default low level, low power hibernation mode. There is no Bluetooth broadcast in this mode
and the serial port cannot communicate.
5.2.2 Wake-up call (computing)
The so-called wake-up mode refers to the module in this mode the module required peripherals in the normal operating
state.
Wake-up mode: Wake-up immediately through the rising edge of PB4 pin;
5.3 Data transmission mode
The module supports 1 data transfer mode: passthrough.
5.3.1 Data passthrough
The so-called data passthrough refers to sending the data received by the serial port, without any processing, to the other
device via BLE, and sending the data received by BLE, without any processing, via the serial port.
5.4 Broadcast
5.4.1 General broadcast messages
Broadcast messages include advertisement and scan response. advertisement is a broadcast message sent proactively, and

Note: This data does not require user configuration.
5.5 Configure
The module supports two configuration methods: serial configuration and over-the-air configuration. These two
configuration modes are basically the same, before the air configuration must be through the AT + AUTH = 123456
authentication password, i.e., to the remote configuration service UUID input 123456, the module is allowed to use the
air configuration after the authentication is passed. The authentication period for over-the-air configuration is the current
connection, and if the device is disconnected and reconnected, it needs to be re-authenticated.
After the module is in the wake-up state, it is in the configuration mode by default, and can be configured directly
through the AT command.

6. AT instruction
Note: Before sending operation commands, first ensure that the module is in wake-up mode, otherwise it will not be able
to receive configuration commands.
6.1 AT commandsDescription
All AT commands do not require carriage return (\r) or line feed (\n).
All AT instructions are case sensitive
AT instructions return results ending in \r\n (except return to HEX)
AT instructions are automatically recognized in wake-up mode, and error instructions are transmitted as data.
