lt_pairing_key_write()

lt_ret_t lt_pairing_key_write	(	lt_handle_t *	h,
		const uint8_t *	pairing_pub,
		const uint8_t	slot
	)

Warning

The pairing keys reside in I-Memory, which has narrower operating temperature range (-20 °C to 85 °C) than the rest of TROPIC01. New CPU firmware versions (v2.0.0 and newer) return error when the operation is unsuccessful, but with older firmwares the operation fails silently. If you use CPU firmware older than v2.0.0, make sure to manually check whether the pairing key was correctly written if operating outside this range. Refer to datasheet for absolute maximum ratings.

Parameters

h	Handle for communication with TROPIC01
pairing_pub	32B of pubkey
slot	Pairing key lot SH0PUB - SH3PUB

Return values

LT_OK	Function executed successfully
other	Function did not execute successully, you might use lt_ret_verbose() to get verbose encoding of returned value
