RE: No connection to nrfcloud

[quote user="gersto"]Thanks for your tip, but I don't understand it.[/quote]

The lte_link_control library uses the unsolicited +CEREG notifications to see if the device has been granted PSM by the network. For this to work, the +CEREG notification level must be set to 5, but the Link Monitor sets it to 2. This can potentially cause some problems. But, that doesn't seem to be the case here.

I have some problems understanding exactly what is wrong. According to the log you posted, it seems the device is connected to nRF Cloud as it should:

Are you sure you are looking at the right device, or that the device is associated with the right account?

Could you explain a bit more what you are seeing in nRF Cloud?

Hello,

Thanks for your tip, but I don't understand it. I image a default asset-tracker application and monitor the start with the LTE Link Monitor. When I configure e.g. "Automatic requests" what influence had this on the application start.

I try your tip but nothing changed. In the nrfcloud I will always see "Device added to account. Waiting for it to connect..."

Best regards

Hi,

From the logs, it seems like things are mostly working as it should.

Could you try again, but this time with "automatic requests" turned off, and not pressing the 'AT+CFUN?' button?

Best regards,

Didrik
