Hi,
In my experience this is mainly related to the content format (CoAP Option 12).
Wakaama server seems to use text, leshan TLV.
The LWM2M TS has seen some clarification on that.
So could you provide the information, which content format option was used?
Mit freundlichen Grüßen / Best regards

Subject: [wakaama-dev] Leshan server communicating with a Wakaama client - 4_06 NOT ACCEPTABLE error
Hi Folks,
Has anybody managed to have a Leshan server communicating with a Wakaama client?
After the one-byte Payload Marker (0xFF) the Wakaama server only sends the payload e.g. ‘FF 31’ – when sending the client a resource value of `1`.
The Leshan server seems to send a ‘header’ within the payload. Taking the same example, sending the client a resource value of `1` to the Wakaama client, it would display ‘FF
C1 01 31’ as the payload in the wakaama client console. The Wakaama client responds with a 4_06 NOT ACCEPTABLE error.
Does anybody know what these bytes represent and a workaround to have a Leshan server communicating with a Wakaama client?
Many thanks
John
