The LR1262 Node Board can be configured for USB-TTL communication.

thinknode_g1

Note: After the program is burned, you need to power off the LR1262 Node Board, and then power on it again!

Through the SSCOM serial tool, send AT commands to configure the LR1262 Node Board as an OTAA/ABP node application established in the TTN, and through sending AT commands, join the LR1262 Node Board to the LoRaWAN network, complete the networking communication with the gateway, and upload the real-time node and gateway communication data between the node and the gateway is uploaded to the TTN server.

Use OTAA mode to join the LoRaWAN network (LR1262 Node Board uses the network entry mode by default)

Step 1: Open the SSCOM serial port tool in the Serial Port Assistant, select the USB COM port recognized by your computer, and then click “EXT”, as shown below.

thinknode_g1

Step 2: Select and input the AT command information as follows on the extended interface of the serial port assistant:

(1) Serial port setting

1, baud rate: 9600
2, check the serial port carriage return line feed
(2) Node access to the single-channel gateway configuration steps (send AT commands)

1、AT + RFS: clear the flash memory, every time you set up the access frequency band or re-entry, you have to send this command to clear the flash memory of the internal chip of the LR1262, otherwise it will affect the module. This instruction must be sent to clear the flash memory of the internal chip of LR1262 every time before setting the access band or re-entering the network.

2、AT+RESET：LR1262 node module reset instruction, you need to reset LR1262 module before re-entering the network.

3、Select the node as single channel/multi-channel mode: AT+ChannelMode=0 (0 is single channel, 1 is multi-channel).
4、set the node into the network band: AT + BAND = 8, (5 for the 868 band, 8 for the 915 band, if it is a single-channel mode, the instruction is AT + BAND = 8,x (X for the selection of the band number 868 optional (0-2), 915 optional (0-7))).
5、Set node DevEui：AT+DevEui=70B3D57ED006**** (Red part corresponds to TTN server)
6、Set node AppEui：AT+AppEui=220033001100**** (Red part corresponds to TTN server)
7、Set node AppKey：AT+AppKey AppKey=F80013BC56A2B55375E467CBE5D9**** (the red part corresponds to the TTN server)
