CC1352R: Start BLE in the middle of the code

Part Number: CC1352R
Other Parts Discussed in Thread: BLE-STACK

Tool/software:

Hi,

I am trying tohave my device without the BLE started until an input is pressedm at this moment I would activate it, and mantain it activated. How could I do this??

I have this function, and I have to use it at the beginning of the code in order to have the BLE running...how could I move it to another part of the code??

void BLE_createTask(void)
{
/*UART_init();
UartLog_init(UART_open(CONFIG_UART_0, NULL));*/

/* Register Application callback to trap asserts raised in the Stack */
RegisterAssertCback(AssertHandler);

/* Update User Configuration of the stack */
user0Cfg.appServiceInfo->timerTickPeriod = Clock_tickPeriod;
user0Cfg.appServiceInfo->timerMaxMillisecond = ICall_getMaxMSecs();
/* Initialize ICall module */
ICall_init();
/* Start tasks of external images - Priority 5 */
ICall_createRemoteTasks();
Task_Params bleTaskParams;
/* Configure BLE Task */
Task_Params_init(&bleTaskParams);
bleTaskParams.stack = bleTaskStack;
bleTaskParams.stackSize = BLE_TASK_STACK_SIZE;
bleTaskParams.priority = BLE_TASK_PRIORITY;
bleTaskParams.arg0 = taskBLELOG;
Task_construct(&bleTask, BLE_taskFxn, &bleTaskParams, NULL);
}

Thanks!

Hi Sandra,

If I were you I would allow the BLE-Stack to initialize at the start of the code. There are a couple of resource demanding operations such as generating a seed for the crypto operations with the TRNG.

The radio will not actually start sending any BLE-related packets until you call GapAdv_enable() (i.e. enable advertisements). So my recommendation would be to move this API to where in the code you actually want to start BLE advertisements.

Cheers,

Hi,

My problem is that when I put the function BLE_createTask() at the begining of the code, my subghz communication stops receiving data. It can send data but it is not receiving.

So the idea is once the input is pressed, I enable the BLE and stop the subghz communication, but i can not make this works..

Any idea will be welcome

Thanks,

Sandra.

Hi Sandra,

I see. When you have more than one RF protocol you will need to use the DMM, dynamic multi mode manager, to handle the RF scheduling and radio reconfiguration between your sub-1 and BLE commands.

We have instructions on how to add BLE to your sub-1 project here:

Hi,

I was trying to avoid to use the DMM due the complexity of my code. But if there is no other option I will implement it.

Many thanks,

Sandra
