Task CLIF NxpRdLib component stack for communication:
12.3 Task HIF
Task HIF is implemented in
smart_lock_task_hif.c
.
After the task starts it initializes custom
BAL and HAL layers that implement
QN ↔ PN
communication protocol. Next it tries to
perform the handshake between the QN and PN. When the handshake is successfully
performed it initialize the custom
PAL
layer, which is used to initialize
NxpRdLib
software
stack and then perform the token retrieval.
12.3.1 Task HIF NxpRdLib component stack:

12.3.2 phbalReg_Smart Lock _DataParams_t
phbalReg_Smart Lock _DataParams_t
component can be found at
comps/phbalReg/src/Smart Lock Serial/phbalReg_Smart Lock Serial.c
. The file contains
the low level implementation of the communication protocol.
12.3.3 phhalHw_Smart Lock _DataParams_t
phhalHw_Smart Lock _DataParams_t
component can be found at
comps/phhalHw/src/Smart Lock /phhalHw_Smart Lock .c
and implements the
phhalHw_Smart Lock _Exchange
function with buffering and manipulation of the data for
upper layers.
12.3.4 phpalMifare_Smart Lock _DataParams_t
phpalMifare_Smart Lock _DataParams_t component can be found at
comps/phpalMifare/src/Smart Lock /phpalMifare_Smart Lock .c and is a wrapper used by
the upper layers.
