Azure IoT Hub connectivity issue

[Neso]

Hi.

We have a device connected to Azure IoT Hub with telemetry interval set to 10 min and on interupt. Tried changing interval to every hour, but then it looses connection. I see there is a known issue CIA-351 that seems to be the same thing. Any way to work around this without using to much power?

Hi,

The workaround described in CIA-351 is the best one we got. If we had a better workaround, we would have listed it in the Known Issue.

Don't think I understand the one mentioned. Different interval on telemetry and psm/drx? One to keep psm/drx alive and one to send telemetry?

Here is from Known Issues:

"
Workaround: Avoid using LTE Power Saving Mode (PSM) and extended DRX intervals longer than approximately 30 seconds. This will reduce the risk of the issue occurring, at the cost of increased power consumption.
"

Is this the one you refer to?

The Azure IoT sample has a 10 min interval. How do I set the PSM and DRX interval to 30sec?

See this DevAcademy lesson on how to configure these:

The lesson before that should explain how to set these numbers I believe.
