Modify Asset Tracker v2 without AWS (NCS v1.5.0)

patricab

Hi.

Is it possible to modify the Asset Tracker v2 example to work without AWS entirely in NCS v.1.5.0? or is it a lost cause?

Was thinking about combining UDP samples for communication with a private server.

Have tried turning off some of the AWS settings in prj.conf, but I only end up with build errors.

Thank you in advance ;)

    Hi,

      

    Is it possible to modify the Asset Tracker v2 example to work without AWS entirely in NCS v.1.5.0? or is it a lost cause?

    The purpose of the asset tracker is to show communication towards nrfcloud. If you need to use another protocol towards another server, especially if udp based, I do not think this is the easiest path to obtain that goal. What is the end goal here, ie. which server or service are you going to communicate with?

     

    Basic UDP connection can be setup with only a few lines of socket based code, like shown in this example:

    https://github.com/nrfconnect/sdk-nrf/blob/master/samples/nrf9160/udp/src/main.c

     

    Kind regards,

    Håkon

    I also get this error message after running west build with most of the AWS IoT settings turned off in prj.conf

    Hi,

    My bad. Was planning on setting up a connection to a private server using CoAP. I wanted to add this a module in the Asset Tracker v2 example, since I need a lot of the functionality that the example uses for my own project.

    I still think you're going down the least easy path here. If you provide more information towards the specific server/service you're planning to connect to, I might be able to give you better advice.

    Which web service are you going to connect to? If its a private server that uses CoAP, you might want to look at the "coap_client" sample. Is this a LWM2M server you're connecting to? LWM2M uses CoAP, and adds logic on top.

     

    Kind regards,
