#include <include/nrf_edgeai_obsv/nrf_edgeai_obsv.h>

Encode multiple contexts as a CBOR list (obsv-list format).

Produces the wire format obsv-list = [+ obsv-payload] defined in obsv.cddl: a CBOR array with one obsv-payload element per context, each encoded under its own context lock. Suitable for any transport (Memfault CDR, UART, BLE, etc.).

Requires CONFIG_NRF_EDGEAI_OBSV_ENCODE.

Parameters

ctxs	Array of n initialized context pointers.
n	Number of contexts. Must be 1–23 (CBOR tiny integer limit).
buf	Output buffer.
max_len	Size of buf in bytes.

Returns

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