LoRaWAN adaptive data rate (ADR)

0

Hello together,
I'm using the LNS from AWS-IoT Core for LoRaWAN and it is working fine.
After activating some nodes in different positions, I see some odd behavior regarding ADR (adaptive data rate). At first, SF8 is used. After some time it switches to SF7 and "silences" the node (only few packages get through). A lot of time later (~24-48h) the SF is set to 12 and immediatly set to SF8 before going down to SF7 again.
My question here: How does the ADR algorithm in the LNS from AWS work? I found nothing in the documentation.
This would show why the node is getting silenced over and over again.

Thanks in advance Nick

Hi Nick. Unfortunately we have no public-facing documentation detailing the ADR implementation. Could you please open a support case? If so, the support team will be able to analyze your logs and advise what's going on.

  • Hi Greg, thats very unfortunate. My support plan doesn't include technical issues.
    Is there any other way to get support? There seems to be no public information, I shouldn't be obliged to pay for "basic" technical support.
