This command is only for low-level usage. Instead of using it, it is recommended to use the high-level wrapper brp_create_secure_channel()

Parameters

protocol	device against which the library shall authenticate
sec_mode	see BRP_SECMODE_ constants. By default BRP_SECMODE_STD
key	the key that shall be used to establish a secure channel. Please note that this key is copied and stays in memory until calling brp_destroy(protocol)
iv	next IV (has to be initialized to 00 ... 00 00). Is only relevant if BRP_SECMODE_STATELESS is not set (otherwise may be NULL). ATTENTION: This value will change and the changed value has to be passed to next brp_secured_send_frm()!!!
cmd_code	Same as cmd_code in brp_secured_send_frm(). Required for correct error codes.
resp_frm	Reference to a frame, where the response shall be stored (=added).
timeout	maximum time to wait for response. If more time is required BRP_ERR_TIMEOUT
