PTA APIs in BLE_Stack library:
Two APIs are designed in BLE_Stack library.
BT_SYS_PtaInit: It is called
within APP_PtaInit() to enable BLE stack PTA feature.
BT_SYS_PtaWlanActiveIrqHandler: It is called within
APP_PtaWlanActiveIrqHandler() to handle WLAN_ACTIVE signal.
MCC configuration: Below MCC
configurations will apply when BLE MCC component PTA option is enabled.
Modify GPIO MCC configuration
to fit PTA pin definition.
Including app_pta_handler.c
and app_pta_handler.h to project.
Generate application template
code to call APP_PtaInit() in APP_BleStackInitAdvance().
BT Request priority design:
Except for the BT device is scanning for advertising packets or RSSI measurements
for channel classification, others BT activities are high priority.
