data_len

uint8_t bt_fast_pair_fhn_pf_ranging_tech_payload::data_len

Length or size of the technology-specific payload data in bytes. This field describes the length of the bt_fast_pair_fhn_pf_ranging_tech_payload::data buffer if this structure is used as the input parameter. Otherwise, if it is used as the input/output parameter, it describes the size of the buffer and is expected to be modified by the function that encodes the payload.

This field never accounts for the length of the Ranging technology ID and Size fields.
