HI Ti,

I have a question about the "Util_constructClock" function.

Like this:

Util_constructClock(&periodicClock, SimpleBLEPeripheral_clockHandler, 100, 0, false, NULL);

Then, the BlueTooth(With CC2640R2) signal should be sent 10 times per second.

However, when I use it as below:

Util_constructClock(&periodicClock, SimpleBLEPeripheral_clockHandler, 1, 0, false, NULL);

The BlueTooth signal cannot be sent about 1000 times per second. It’s slower.

Then actually, how much time does the CC2640R2 consume, when I set the clock to 1ms duration?

Thanks.

Hi,

The clock module itself can do 1ms interrupt if needed. This however assumes what ever handler function you use is fast enough to support this.

So to answer your question, I suggest you have a look at SimpleBLEPeripheral_clockHandler and the work it performs, and maybe use IO toggles (or timestamps) to time the execution in your application.
