DR Stagnant Despite Optimal Signal and ADR Status (ChirpStack v4)

ChirpStack Network Server
1

Hello all,
I’m puzzled as to why the Data Rate (DR) didn’t increase. I’m currently using a Milesight AM103-AS923.
As shown in the screenshot, the sensor’s data interval is set at 10 minutes, while the expected uplink interval in the Device profile is 30 secs, Device-status request frequency is 30. The RSSI and SNR values for the sensor are excellent, and the ADR status is true.

Although the sensor has maintained this status for 2 days, the DR remains stagnant at 2, and the ADR functionality is still not operational.

How is your regional .toml configured? I would start by verifying your ADR settings there.

Added to that, also inspect the LoRaWAN frames. It could be that ChirpStack does send mac-commands to your device as downlinks, but that your device does not ACK these.

Hi @brocaar

Thank you for your reply as well.
I didn’t observe mac command LinkADRReq. Should I wait for longer? When will Chirpstack send the mac command LinkADRReq?

Hi @brocaar @bconway,

Do you have any insights on this matter? I’ve reviewed all the settings, and they are normal. Because I have 10 tenants under my ChirpStack, only one is experiencing this particular issue.

Thanks!
