RAK7204 AT Command Manual

You can configure your RAK7204 WisNode Sense Home by sending AT Commands via a Serial port tool running on your PC. The following list shows the AT Commands that you can use:

The AT commands can be classified in the following groups:

Read Command : Reads the current configuration or status of the board. The command name and the list of parameters are separated by = 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 board. The command name and the list of parameters are separated by = character. The <m> parameter is separated with its associated value <n> by the : character.

at+set_config=<m>:<n>

Operational Commands : There are also commands that are neither read nor write commands. The purpose is to execute an action, for example:

at+send=lora:<m>:<n> // Sends data through the LoRa transceiver.

Special Command : The RAK7204 UART port has two operational modes: Configuration Mode and Data Transmission Mode. When switching from data transmission mode to configuration mode the command to be entered is +++ and does not contain terminators such as \ r and \ n.

After executing the command, a response is sent back to the external MCU. The usual reply has the following format:

OK [information]\r\n

NOTE

Only the read commands have information in the replied message, while Write commands do not have an informative description.

The firmware developed running in the external MCU will expect at a minimum 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, you will receive a response in the following format:

ERROR: [ErrCode]\r\n

Error Code Table

Error Code	Description
1	The last command received is an unsupported AT command.
2	Invalid parameter in the AT command.
3	There is an error when reading or writing the flash memory.
4	There is an error when reading or writing through IIC bus.
5	There is an error when sending data through the UART port.
80	The LoRa transceiver is busy, could not process a new command.
81	LoRa service is unknown. Unknown MAC command received by node. Execute commands that are not supported in the current state, such as sending `at+join` command in P2P mode.
82	The LoRa parameters are invalid.
83	The LoRa parameters are invalid.
84	The LoRa data rate (DR) is invalid.

86	The device has not joined into a LoRa network.
87	The length of the packet exceeded that maximum allowed by the LoRa protocol.
88	Service is closed by the server. Due to the limitation of duty cycle, the server will send "SRV_MAC_DUTY_CYCLE_REQ" MAC command to close the service.
89	This is an unsupported region code.
90	Duty cycle is restricted. Due to duty cycle, data cannot be sent at this time until the time limit is removed.
