RAK5205 WisTrio LPWAN Tracker AT Command Manual
Introduction
The purpose of this section is to demonstrate on how to configure the RAK7205 LPWAN Tracker thru the use of AT Commands via a Serial Port Tool running in your Windows PC. The list below shows the AT Commands available for use:
AT Command Syntax
The AT command is based on ASCII characters. In general, the AT Command starts with the prefix AT or 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 in 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
=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
=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 RAK7205 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\ rand\ 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
Only the read commands have information in the replied message, while Write commands do not have an informative description.
After sending a successful command to the module, the firmware developed, running in the external MCU, will expect at a minimum string of Ok\r\n. On the other hand, when the command is not successfully executed by the module, you will receive a response with the following format:
ERROR: [ErrCode]\r\n
Error Code Table
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. |

| 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. |
| 91 | No valid LoRa channel could be found. |
| 92 | No available LoRa channel could be found. |
| 93 | Status is error. Generally, the internal state of the protocol stack is wrong. |
| 94 | Time out reached while sending the packet through the LoRa transceiver. |

| 98 | There is an error while receiving a packet during the LoRa RX2 window. |
| 99 | Failed to join into a LoRa network. |
| 100 | Duplicated downlink message is detected. A message with an invalid downlink count is received. |
| 101 | Payload size is not valid for the current data rate (DR). |
| 102 | Many downlink packets are lost. |
| 103 | Address fail. The address of the received packet does not match the address of the current node. |
| 104 | Invalid MIC is detected in the LoRa message. |

LoRa P2P Type AT Command
-
at+set_config=lora:work_mode:
<mode>
This command is used to switch the LoRa transmission mode between the LoRaWAN and the LoRAP2p mode. This command will cause the module to restart once applied.

| Operation | Command | Response |
|---|---|---|
| Write | at+set_config=lorap2p: transfer_mode:<mode> | OK |
Parameter：
| mode | 1: receiver mode 2: sender mode The default is sender mode. |
Example：
at+set_config=lorap2p:transfer_mode:1\r\n
OK
-
at+send=lorap2p:
<data>
This command is used for sending data through LoRaP2P, and only valid when the LoRa work mode was set to LoRaP2P before.
| Operation | Command | Response |
|---|---|---|
| Send | at+send=lorap2p:<data> | OK |
Parameter：
| mode | 1: receiver mode 2: sender mode The default is sender mode. |
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 >
Sensor AT command
- at+set_config=device:gps_timeout:time
This command is used to set the timeout of searching GPS satellite.
| Operation | Command | Response |
|---|---|---|
| Write | at+set_config=device:gps_timeout:<time> | OK |
Parameter:
| time | Time in seconds. |
Example：
at+set_config=device:gps_timeout:120\r\n
