SES CMAKE ERROR

[dhandzic]

I have installed the latest SDK 1.3.0 using the Toolchain Manager.

I would now like to open nRF Connect SDK Projekt and get the follwoing error:

I have added the CXX environment variable, but it did not help

[Didrik Rokhaug]

When we look at the IP packets sent in the trace, the network replies with "Destination port unreachable" messages.

What port is the server listening to?

The DK tries to connect to port 5684

[Robert K]

Oh the server is listening on the default port, 5683. ipv4

5684 is bootstrap server? We did try that aswell, no luck

[Didrik Rokhaug]

Looking at the Leshan Github page, they use both 5683 and 5684 for the LwM2M server, and 5783 and 5784.

You can change the port used by the DK by changing the value of CONFIG_LWM2M_PEER_PORT on line 37 in the prj.conf file of the lwm2m_client sample.

Did you try to change the port on the device or the server side?

[dhandzic]

We have the LWM2M_PEER_PORT set to 5684.

[Didrik Rokhaug]

Try changing it to the port the server is listening to.
