Hi all,
I've ported a LWM2M Client (Wakaama) on an "mbed" platform and I'm using Ethernet to connect to leshan LWM2M Server sandbox (
http://leshan.eclipse.org/).
I'm able to register (see the Device, Server and Test Objects) and able to perform read, write and execute requests.
So, I can send COAP messages and see ACKs, and on the mbed I can see "received xx bytes" debug output.
However, at times (it appears to be a random process), I see that COAP messages are sent but I do not receive any reply and I see the usual "0 bytes received" on the "mbed" UDP Socket, corresponding to no activity.
Then, the web interface reports:
"Unable to read resource /1/0/0 for UniS_Testbed_Full_Client_Trial : 500 Request timeout"
After a while (or after I do a reboot and re-registration) I'm then able to send/receive again for some time until it hangs again.
What could likely be the cause?
Thanks and Kind Regards,
Riccardo.
