Re: [wakaama-dev] wakaama-dev Digest, Vol 30, Issue 3

Hello again, sorry for late reply.

I was checking how I could modify the code to implement re-transmission.
If I correctly understood the code, I could take advantage of the existing code that manages transactions and handle the end of transmission with transaction callback.

We need to handle transmission of historical data from device to server and we'd like to remove pending  old data as soon as a transmission has successfully completed.

Do you think there are any other reasonable way to handle historical data?

Hi,

By default notifications are sent as Non-Confirmable messages. But it is standard-compliant to send them as Confirmable messages. However wakaama does not use the retransmission mechanism for notifications and does not have an interface to be informed of transaction failure for notifications. You would have to modify the code.

Regards,
David Navarro

Hi everybody,


I have some questions about client usage but as of now the most urgent is the following: I need to let my application to know when wakaama was not able to push change notification of a given observable resource. Is it possible and, if yes, how?

Cheers,
