Problem with the wakaama example

Help
1

Hey there,

as a total LWM2M noob I wanted to play around with the Wakaama example, but didn’t get it to work. I tried to follow the README, but in both cases (without and with bootstrap server) the application seems to run into a timeout. I tested with native and the basic communication between RIOT and the server seems to be working - at least I see a CoAP exchange in Wireshark.

From the application I get the following output:

[lwm2m_step:382] State: STATE_REGISTERING
[registration_getStatus:506] State: STATE_REGISTERING
[registration_getStatus:513] targetP->status: STATE_REG_PENDING

...

Am I missing something here?

Hi @oleg ,

could you maybe show the Wireshark dump? I’m guessing you’re using a Leshan server? I remember sometimes I had issues with the IP matching, as the server would respond with a different IP address than the one configured in the client. IIRC I had to manually set the address in the server when running the .jar file with an option flag.

Cheers, Leandro
