Hi Achim,
I think Wakaama has the right numbers here, I see LWM2M_CONTENT_TLV=11542 and LWM2M_CONTENT_JSON=11543 in liblwm2m.h under lwm2m_media_type_t.
In all the objects, everytime lwm2m_data_new(X) is called, (i.e. when the server is asking the full object or when I ask AVAILABLE_POWER_SOURCES in the Device Obj) in Wakaama, there seems to be an issue with a format response (the “image/jpeg” I can see from CoAP messages).
Thanks and Kind Regards,
Riccardo.

Subject: Re: [leshan-dev] Leshan Issue with Content-Format following update to M15
Hi Riccardo,
just as additional information:
“unknown/11542”
Is TLV, the “new” IANA number. The old number 1542 was just an “example number”, not registered at IANA.
Many “older” implementations may use 1542 and don’t understand 11542.
Mit freundlichen Grüßen / Best regards

Hi,
I’ve just updated to latest Leshan. When I get the data of a single resource as such, it works:
CON-GET Uri-Path: "1", "0", "0" - Accept: "text/plain"
ACK-2.05 Content-Format: "text/plain" 1
However, when I try to get a full instance (or data as /3/0/6 or /3/0/7), it doesn’t work and return an acknowledgement with content format image/jpeg (?):
CON-GET Uri-Path: "1", "0" - Accept: "unknown/11542"
ACK-2.05 10916 8953 Content-Format: "image/jpeg" Hex:c10001c2010096c10200c10301c10500c10600c2075551
Plus, I do get:

Any idea, how to fix this?
