GATT

Hardware MAC• Firmware or application are not

involved in the radio timings• Can be patched if changes required• Upper stack up to GATT is

implemented in firmware

Application is compiled against the

firmware library• Code executes from ROM and RAM• Most of the firmware (apart from

optional features) is in ROM• The available application size is up to

50KBytes

GATT

Application runs in a safe

sandboxed environment with

access to hardware through

firmware API• Application executes at the same

priority as firmware library at full 16 MIPS

• Time-critical, isolated execution is available for subroutines running on PIO controller

• The application cannot interfere with the radio events and timing

12

Qualcomm® µEnergy™ software architecture

User application is linked with the

firmware library to produce a final

image

Event-driven architecture• User application has to implement

firmware callbacks for various events in the application life cycle

• Application communicates with firmware using firmware API calls

13

AppPowerOnReset

Called on the cold boot and before

any other application callbacks

14

AppInit

Called on every boot

Should contain application

initialisation• Hardware setup• Upper stack initialisation (e.g. setting

up GATT Server database)

15

AppProcessSystemEvent

Called by firmware to process

system-level events• Low battery• Input PIO level change (e.g. to handle

buttons, external signals etc.)• WAKE pin level change• Interrupt from PIO controller

16

AppProcessLmEvent

Handles communication link-

related events from firmware• GAP and (G)ATT messages• Security Manager messages• Low-level link layer messages• Radio events

17

Timers

Run on top of the hardware timer

with microsecond accuracy
