handshake failed with Orange Live Objects

[SebDominguez]

Tying to run Anjay-freertos-client-B-L462E-CELL1-TYPE1SC.bin with Orange Live Objects but I keep getting handshake failed: -26624

I can see on my Orange Live Objects dashboard a Handshake Client Key Exchange event:

I'm out of idea to make this working.

Here's a complete trace from my B-L462E-CELL1 board:

Alright the solution was to configure the PSK on the client in plain ASCII and the PSK on the server in HEX.

For instance: 4d795374726f6e6750617373776f7264 on the Orange Live Objects config and MyStrongPasswordon the Anjay config.

That's definitely a gotcha for newbies...

Hi!

Good to hear that you have managed to overcome this problem. This actually sounds like something that Orange Live Objects Server provider should warn about, although I am not familiar with this environment. In Coiote LwM2M Server which is developed and maintained by AVSystem, there is a possibility to set and view PSK in both plaintext and hex format. Anjay does provide OMA LwM2M Specification conformance and thus interoperability with any LwM2M Server that is the protocol specification compliant as well, but our tutorials and demos are based on communication with Coiote Server as that's our ecosystem and there we are able to provide support on both ends.

If you have any other troubles or concerns, don't hesitate to reach us.

Regards, Tomasz

Thank you very much for your reply Tomasz. Do you have a dedicated channel for support? Some of my problems aren't related to the Anjay OMA LwM2M implementation and filling an issue for those seems to be off-topic in this GitHub issues tracker.
