3. CC2650 Platform Main CPU : ARM Cortex-M3 processor
handles Application layer and
Protocol stacks.
Radio Core
: ARM Cortex-M0 processor
handles all the low-level radio control
and processing about PHY, Link layer.

6. Application

7. Sample Project Build Application Build Stack Run -> Debug Stack
Run -> Debug Application
If Stack Project Not Modified,
the only steps are 1 -> 3.

8. Main() Priority Task 5 BLE Protocol Stack task 3
GapRole task (peripheral role) 1
Application task (SimpleBLEPeripheral)

9. Icall Service BLE Protocol Stack Service Primitive Service
Application <-> Stack
Enable independent updating of application / stack
Primitive Service
Messaging and Thread Synchronization
Heap Allocation / Management

10. Prior to Icall At Stack, enroll Icall At App, register with Icall
(in OSAL_ICallBle.c)
At Stack, enroll Icall
At App, register with Icall
(in simpleBLEPeripheral.c)

11. Icall Functionality Icall Initialization and Registration
(in simpleBLEPeripheral.c)
Icall Initialization and Registration
Icall Thread synchronization
Semaphore is signaled by two conditions.
(enqueueMsg or Icall_signal)
(in simpleBLEPeripheral.c)

12. Icall Usage
1. Inter-task Messages
(in simpleBLEPeripheral.c)

13. Icall Usage
2. Inter-Task Events
(in peripheral.c)

14. Icall Usage 3. Messages Posted to the Application Task’s RTOS Queue
Callback Func
(in simpleBLEPeripheral.c)

15. Icall Usage
4. Event Signaled Via the Internal Event Variable

16. Icall Usage 5. Callback The actual callback
The function to process in the application context
Popped from queue

17. BLE Protocol Stack
CC25xx -> CC26xx

18. GAP Connection Functionality Directly Call GAP API
Device discovery, link establishment, link termination
Initiation of security features, and device configuration
Directly Call GAP API
(in simpleBLEPeripheral.c)

19. GAPRole Task – Peripheral role
1. Initialize GAPRole parameters
2. Initialize the GAPRole task

20. GAPRole Task – Peripheral role
Send GAPRole commands as desired from the application
APP -> Stack
ICall

21. GAPRole Task – Peripheral role
Process most of the GAP-related events passed
to Application from Stack
Stack -> APP
ICall
GAPRole
Application
