Configuration commands for Dragino nodes

Step 1: We can use Easy LoRaWAN Cloud to send downlink payloads to set configuration settings.

Step 2: To prepare downlink payloads to send to nodes

Converter

Reboot (ATZ)

• 04FF

Uplink Interval (AT+TDC)

• 0x01XXYYZZ (0x01 + 3 bytes)
• 30s => 0100001E
• 60s => 0100003C
• 10 minutes (600s) => 01000258
• 30 minutes (1800s)  01000708 => 0x0708
• 60 minutes (3600s) =>  01000E10

Single or multiple uplinks (AT+DATAUP)

• Single uplink: AD00
• Multiple uplink: AD01

Uplink size (AT+DWELLT)

• Longer than 11-byte uplink: 2500 // AT+DWELLT=0 (The node will auto reboot after this command.)
• Shorter then 11-byte uplink: 2501 // AT+DWELLT=1 (Default)

Force rejoin

• Default 1-2 days: 320105A00B40
• Shorter 60-90 minutes: 3201003C005A

(For RS485) To set baud rate

• A7 01 aa bb => AT+BAUDR=hex(aa bb)*100
• AT+BAUDR=4800 => A7010030
• AT+BAUDR=9600 => A7010060

(For RS485) Clear all AT+COMMANDx…

• x=1-F: 09010F

(For RS485) To set AT+COMMANDx

• AF MM NN LL a1 b2 c3 c4 d5 d6 YY
• MM: the AT+COMMANDx or AT+DATACUTx to be set. Value from 01 ~ 0F
• NN: 0: no CRC; 1: add CRC-16/MODBUS ; 2: set the AT+DATACUT value
• LL: The length of AT+COMMAND or AT+DATACUT command. Usually 06.
• a1 b2 c3 c4 d5 d6: AT+COMMAND or AT+DATACUT command
• YY: If YY=0, RS485-LN will execute the downlink command without uplink; if YY=1, RS485-LN will execute an uplink after got this command.
• Example:
• AT+COMMAND1 => AF 01 01 06 01 03 20 10 00 01 00
• AT+DATACUT1 => AF 01 02 04 05 01 04 05 00

(For RS485) To run test command AT+CFGDEV

• A8 MM NN XX XX XX XX YY
• MM: 1: add CRC-16/MODBUS ; 0: no CRC => 01
• NN: The length of RS485 command => 06
• XX XX XX XX: RS485 command total NN bytes
• YY: How many bytes will be uplink from the return of this RS485 command
  • if YY=0, RS485-LN will execute the downlink command without uplink;
  • if YY>0, RS485-LN will uplink total YY bytes from the output of this RS485 command; Fport=200
  • if YY=FF, RS485-LN will uplink RS485 output with the downlink command content; Fport=200.
• Example: a8 01 06 01 06 07 D0 00 02 00

(For RS485) To set MBFUN

• AT+MBFUN=1 => a901
• AT+MBFUN=0 => a900

(For RS485) to set command delay

• AT+CMDDLaa=hex(bb cc)*1000 => 0x AA aa bb cc
• AT+CMDDL1=2000 => aa0107d0
