RAK4600 Module AT Command Manual
Introduction
The RAK4600 module is designed to simplify LoRa P2P peer-to-peer and LoRaWAN communication. This module saves customers in dealing with complicated SPI protocol with the LoRa transceivers. Instead, a well-known serial communication interface is provided to send commands and request the internal status of the module. This approach allows a straightforward way to integrate LoRa technology into your projects.
On top of this serial interface, a set of AT commands is defined wherein an external microcontroller will be able to control the RAK4600 module as a classic AT modem. Through the AT commands, customers can set parameters of the LoRaWAN communication, controlling GPIO pins, analog inputs, etc.
In the RAK4600 module, the serial communication is exposed on the UART1 port, through Pin 22 (USART1_RX) and Pin 23 (USART1_TX). The parameters of the UART1 communication are 115200 / 8-N-1. The firmware upgrade is also possible through this port. To get familiar with the pin distribution of this module and find a schematic circuit of a reference application, refer to the RAK4600 Datasheet.
In addition, the RAK4600 also supports BLE. You can use your mobile phone to communicate with the module via BLE interface, or you can use the module to scan the surrounding Bluetooth beacon information.

AT Command Syntax
The AT command is based on ASCII characters. A command begins with the prefix at and ends with <CR><LF> (i.e. \r\n). The maximum length is 255 characters, which includes the <CR><LF> characters at the end of the command. For the rest of the document, the \r\n part is omitted for the sake of clarity.
The AT commands can be classified into the following groups:
- Read Command: Reads the current configuration or status of the module. The command name and the list of parameters are separated by the
=character. The<m>parameter is separated with its associated value<n>by the:character.
at+get_config=<m>:<n>
- Write Command: Writes/Modifies the current configuration of the module. The command name and the list of parameters are separated by the
=character. The<m>parameter is separated with its associated value<n>by the:character.
at+set_config=<m>:<n>
- Operational Commands: Some commands are neither read nor write commands but are used to execute an action.
at+send=lora:<m>:<n> // Sends data through the LoRa transceiver.
- Special Command: The RAK4600 UART port has two operational modes: Configuration Mode (default mode) and Data Transmission Mode. Data transmission mode allows you to send ASCII payloads directly to the network server via UART without using any AT Command interface like
at+send=lora:X:YYY. Data transmission mode is explained further on Interface Type AT Command section of this document.
To enable data transmission mode, you need to input at+set_config=device:uart_mode:<index>:<mode> command. To switch back from data transmission mode to configuration mode (AT command default mode), the command to be entered is +++ and does not contain terminators such as \r and \n.
After the command is executed by the module, a reply is sent back to the external MCU. In the case the command is successful, the usual reply has the following format:
OK [information]\r\n
Only Read commands have information in the replied message, while Write commands do not have an informative description.
The firmware you developed, running in the external MCU, will expect at a minimum a string of Ok\r\n after sending a successful command to the board. On the other hand, when the command is not successfully executed by the board, a reply will be received in the following format:
ERROR: [Err Code]\r\n

at+set_config=device:uart_mode:
<index>:<mode>
This command is used to set the UART operation from AT configuration mode to data transmission mode.
During data transmission mode, all standard AT Commands will not work, and the data you sent to UART will go directly to the network server as ASCII payload with \r\n. If you input AZ, the network server will receive an uplink hex value of 415A0D0A. This means A=0x41, Z=0x5A, \r=0x0D and \n=0x0A.

-
at+send=lorap2p:
<data>
This command is used to send data through LoRa P2P and is only valid when the LoRa work mode was set to LoRa P2P before.
| Operation | Command | Response |
|---|---|---|
| Send | at+send=lorap2p:<data> | OK |
Parameter：
| data | The data to be sent, and the format is hexadecimal |
Example：
at+send=lorap2p:1234\r\n
OK
In LoRa P2P mode, the receiving node receives the data and outputs the data in the following format:
at+recv=<RSSI>,<SNR>,< Data Length >:< Data >
BLE Type AT Command
-
at+set_config=ble:work_mode:
<mode>:<long_range>
This command is used to configure the BLE mode.
| Operation | Command | Response |
|---|---|---|
| Write | at+set_config=ble:work_mode:<mode>:<long_range> | OK |
Parameter：
| mode | BLE work mode. 0: Peripheral mode (Default) 1: Central mode 2: Beacon scan mode |
| long_range | Long range enable, only ‘0’ can be selected because RAK4600 does not support this feature. |
Example：
at+set_config=ble:work_mode:0:0\r\n
OK

Appendix IV: Pin Description of RAK4600
The pin definition of the RAK4600 module can be reviewed in the Pin Definition section on the Datasheet.
A summary of the pins of the RAK4600 module:
-
About the UART Pin:
- Pin 22 (USART1_RX) and Pin 23 (USART1_TX).
- During sleep, Pin 22 (USART1_RX) is automatically configured as a wake up pin and in external interrupt mode with an internal pull-down resistor. Wake-up will be triggered by a rising edge on this RX pin.
-
About the SWD debug Pin: Pin 37 (SYS_SWDIO) and Pin 38 (SYS_SWDCLK) are used for SWD debug programming.
-
About the Power Pin: The power pins on the RAK4600 module includes the VCC Pins on Pin 40 (3V3_IN) and Pin 41 (3V3_IN), and the ground pins (GND) are on the Pin 1, Pin 8, Pin 12, Pin 13, Pin 14, Pin 16, Pin 18, Pin 19, Pin 20, Pin 31, Pin 39, and Pin 42.
-
About the Reset Pin: The reset pin on the RAK4600 module is the Pin 36 (MCU_NRST);
-
About the RF Antenna Pin: The RF Antenna pins on the RAK4600 module are the pin15 (RF_BT) BLE antenna and Pin 17 (RF_L) LoRa antenna.
-
About the GPIO Pin: The GPIO pins available on the RAK4600 module are Pin 4, Pin 5, Pin 6, Pin 7, Pin 9, Pin 10, Pin 21, and Pin 24.
The subsequent firmware upgrade of the product is carried out through the OTA interface.
