4.2 DOWNLINK COMMANDS TO CHANGE THE CONFIGURATION
It is possible to change the configuration of the device through the LoRa gateway via downlink frames. You can check if
the downlink has been correctly sent because the led will light up
blue. The following are the different payloads for the
GCM v3 device:
1. Time Update (Little Endian)
To change the date and time of the device send a 4 byte frame with desired value in UNIX Timestamp on Port 4.
Example:
- Fri Oct 15 2021 06:45:14 GMT+0000
- 1634280314
- 6169237A
- 7A 23 69 61
2. Change transmission windows (Little endian)
To change the times at which the device sends data send a 2 byte frame with desired value in minutes (UTC Time)
on Port 5.
Example:
- Sending at 00:00 / 12:00
- 0 / 720 (Minutes)
- 0 / 2D0 (Big Endian)
- 00 00 / D0 02 (Little Endian)
3. Change region
To change the region in which the device must operate, send 1 byte on Port 6.
• REGION_AS923 → 00
• REGION_AU915 → 01
• REGION_EU868 → 05
• REGION_KR920 → 06
• REGION_IN865 → 07
• REGION_US915 → 08
• REGION_RU864 → 09
4. Change keys
To modify ABP or OTAA keys send 1 byte with activation mode 01 or 02 respectively and then 16+16 bytes according
to the table on Port 7.
5. Change JoinEUI
To modify JoinEUI send 8 bytes with the new value on Port 8.
