		size_t	max_len )

#include <include/nrf_edgeai_obsv/nrf_edgeai_obsv.h>

Encode all metrics as a CBOR blob under the context lock.

Wire format is defined in obsv.cddl. Size buf for the worst-case encoded payload (see nrf_edgeai_obsv_encode.c for the formula).

Requires CONFIG_NRF_EDGEAI_OBSV_ENCODE.

Parameters

ctx	Initialized context.
buf	Output buffer.
max_len	Size of buf in bytes.

Returns

Encoded byte count on success, 0 on error or buffer overflow.
