◆ lt_pairing_key_invalidate()

lt_ret_t lt_pairing_key_invalidate ( lt_handle_t h,
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 invalidated if operating outside this range. Refer to datasheet for absolute maximum ratings.
Parameters
hHandle for communication with TROPIC01
slotPairing key lot SH0PUB - SH3PUB
