LAUNCHXL-CC26X2R1: Send Notification periodically

Dushan Kumara

Hi,

I'm working with project zero (simplelink_cc13x2_26x2_sdk_5_20_00_52) and I want to send data array of an ADC inputs every second as a notification to mobile app

I've tried using periodic clock and calling service_SetParmeter function of a BLE custom profile but not worked to send notifications every second. Microcontroller was disconnected from the app when I enabled notifications from the app. I succeed to send notification by writing values to the _ValueChangeHandler of the service.

These are the functions I've used.

TimercalClock_Handle = Util_constructClock(&Timercal,TimercalSwiFxn, 50,1000,0,CONFIG_PIN_BTN2);

Util_startClock((Clock_Struct *)TimercalClock_Handle);

static void
TimercalSwiFxn (uintptr_t arg0)
{

Status_reply_SetData();

}

static void
Status_reply_SetData(){

Status[0] = DataIn1;
Status[1] = DataIn2;
Status[2] = DataIn3;
Status[3] = DataIn4;

StatusReply_SetParameter (STATUSREPLY_STATUSREPLIES_ID, sizeof (Status), &Status);

}

How can I send data by every second as an notification?

Than you

Hi Dushan,

Have you looked at our custom profile lab in the SimpleLink Academy? The final step in the lab does almost exactly what you're describing. You will simply have to modify it to use an ADC reading.

Best,

Nate

Hi Nathan

Thanks for your response, Yeah I've gone through that but I'm getting following error for ProjectZero_enqueueMs

void myClockSwiFxn(uintptr_t arg0)
{
// Can't call blocking TI-RTOS calls or BLE APIs from here.
// .. Send a message to the Task that something is afoot.
ProjectZero_enqueueMsg(PZ_MSG_PERIODIC_TIMER, NULL); // Not sending any data here, just a signal
}

error #29: expected an expression

Hi Dushan,

This is a syntax error. It may be an error with how you're using semicolons/parentheses/brackets...etc. You will have to locate the error in your IDE.

Best,

Nate
