lwm2m_security_set_psk()

int lwm2m_security_set_psk	(	uint16_t	sec_obj_inst,
		const void *	psk,
		int	psk_len,
		bool	psk_is_hex,
		const char *	psk_id
	)

#include <include/net/lwm2m_client_utils.h>

Set security object to PSK mode.

Any pointer can be given as a NULL, which means that data related to this field is set to zero length in the engine. Effectively, it causes that relative data is not written into the modem. This can be used if the given data is already provisioned to the modem.

Parameters

sec_obj_inst	Security object ID to modify.
psk	Pointer to PSK key, either in HEX or binary format.
psk_len	Length of data in PSK pointer. If PSK is HEX string, should include string terminator.
psk_is_hex	True if PSK points to data in HEX format. False if the data is binary.
psk_id	PSK key ID in string format.

Returns

Zero if success, negative error code otherwise.
