Don't think so. What makes you think you need two ways? You can check the LWM2M carrier sample in the SDK, it has support for download client.

Thanks Hakon,

LwM2M usage confuses me. Is it for FOTA download? I was planning on downloading new cellular modem firmware via https similar to the “full modem update” sample code. Do I need to be able to download cellular firmware 2 ways? I’ve been speaking with T-Mobile and they never mentioned I needed this. Maybe they just forgot.

I just don’t know enough about how LwM2M operates with carriers. Google searching has not helped. Is this something that is enabled all the time? For example, could I get LwM2M events when I’m operating normally in my device or do I somehow tell the network I’m ready for events? I’m not sure how to integrate this into the device flow since I’m not really sure what it’s supposed to do.

Thanks for any advice,

Chris

You need to also include the lwm2m carrier library when using these networks;

It is mandatory to include the LwM2M carrier library in any AT&T, T-Mobile, or Verizon certified products.

Hi, my original question was if there is anything I need to be concerned about aside from the different APNs. It doesn’t seem that way, but I wanted Nordic to verify this. Thanks.

Hi,

I guess this was answered here: RE: Verizon APN - do I leave it blank?
