AT-Commands

To make it easy to setup the LoRaWAN® credentials, an AT command interface over USB is implemented. It includes the basic commands required to define the node.

Credits:
Taylor Lee (taylor.lee@rakwireless.com)

REMARK 1 After changing LoRaWAN® parameters the device must be reset by either the ATZ command or pushing the reset button.

REMARK 2 The Serial port connection is lost after the ATZ command or pushing the reset button. The connection must be re-established on the connected computer before log output can be seen or AT commands can be entered again.

REMARK 3 The Serial port is setup for 115200 baud, 8N1. It cannot be changed by AT commands.

AT Command syntax

The AT command is based on ASCII characters. In general, the AT Command starts with the prefix AT and ends with <CR><LF> (i.e. \r\n). For the rest of the document, the \r\n part is omitted for the sake of clarity.

The AT commands have the standard format “AT+XXX”, with XXX denoting the command.

There are four available command formats:

AT COMMAND FORMAT Description
AT+XXX? Provides a short description of the given command
AT+XXX=? Reading the current value on the command
AT+XXX=<input parameter> Writing configuration on the command
AT+XXX Used to run a command

The output of the commands is returned via UART.

The format of the reply is divided into two parts: returned value and the status return code.

<CR> stands for “carriage return” and <LF> stands for “line feed”

  1. <value><CR><LF> is the first reply when (AT+XXX?) command description or (AT+XXX=?) reading value is executed then it will be followed by the status return code. The formats with no return value like (**AT+XXX=<input parameter>) writing configuration command and (AT+XXX) run command will just reply the status return code.

  2. <CR><LF><STATUS><CR><LF> is the second part of the reply which is the status return code.

The possible status are:

STATUS RETURN CODE Description
OK Command executed correctly without error.
+CME ERROR:1 Generic error or input is not supported.
+CME ERROR:2 Command not allowed.
+CME ERROR:5 The input parameter of the command is wrong.
+CME ERROR:6 The parameter is too long.
+CME ERROR:8 Value out of range.

More details on each command description and examples are given in the remainder of this section.
