Actinius Icarus nrf9160 issue with asset tracker

[Thomas B]

Hi,

I have managed to upload the asset tracker via mcuboot to my Actinius Icarus.

It should straight-up connect to the actinius.io cloud, but when I check the link monitor it keeps running loops and fails to connect to LTE.

It keeps giving me "Response buffer not large enough" errors.

Any idea where this comes from and how to fix this?

Hi Thomas,

From your log it seems that the device is successfully connecting both to the LTE network and to actinius.io, as it reports that it is registered (app: The device is registered on actinius.io). The crash seems to be coming from the SPUL library that takes care of the A-GPS data. In any case, since this firmware is built by Actinius, I would suggest that you send an email to [email protected] with a full log as above, and information such as the network (if you know it, otherwise just the area of operation) and my colleagues will get to the bottom of it.

Thank you.

BR,

Mike
