simple coap sample to send data to the nrf cloud

[Lorenzo Amicucci]

Hi

the UDP sample is a very nice example for testing LTE Cat M and NB IoT power saving features and RAI, however, it does not show data to any cloud and it does not wait for the ACK,

Now that nRF Cloud with coap has been released, is it possible to have a simple coap sample (similar to our upd sample) that send some simple data (similar to the payload we send on the upd sample) and we can see this in the cloud (at least in the terminal interface)? 

It should be easy to optionally enable at least
PSM - and change the timers

eDRX- and change the timers 

RAI

periodic upload: how often it should send data --> timer should be easily configurable (I guess it can be selected on the device?)

push button --> to send data 

CID should be default enabled.

Device should send the data, wait for ack (coap) and then go back to sleep. 

Is there any sample available that implements this?

Thanks

Lorenzo

Hi, 

Here is the PR https://github.com/nrfconnect/sdk-nrf/pull/12492

The nrf_cloud_multi_service sample has a new overlay overlay_min_coap.conf that will hopefully meet your request.

Regards,
Amanda H.

Hi Amanda, 

I enabled logs, but I cannot connect to the cloud. How do I add the certificates to the device ? and how do I add the device to the cloud? see the errors below. I followed same procedure as asset tracker v2.
(I have even tried to enable CONFIG_NRF_CLOUD_PROVISION_CERTIFICATES=y but at built time this is changed automatically to "n") 

Can you try on your side?

Thanks

Hi,

Please see this section in the documentation which explains how to provision a device to use CoAP with nRF Cloud:
