Hi!

In the SCS I am using the function to generate task alerts:

In the CCS I am trying to process the task alert with the following function:

I am following both the "Sensor Controller Project from Scratch" and the "Bluetooth Low Energy Sensors BoosterPack" tutorials.

The debug occurs successfully, but the variables values never changes (the sensors are working fine, as checked with the SCS Run-Time Logging).

Other option could be to update the characteristic values when a read is asked. Is it possible?

Hi DDD,

Have you remembered to register processTaskAlert() as the task alert callback with the scifOsalRegisterTaskAlertCallback() API?

Hi Edvard,

I think so. In the images above you can see what I have done:

I removed the processTaskAlert() from the scTaskAlertCallback() and inserted the instruction to print in putty the message "----------Task ALERT!!!----------: 1/2/3/...".

However, this message is never printed.

In order to check if the BLE setParameter was working, I inserted the following code in the buttonCallbackFxn():

This way, the values are updated every time I press one of the buttons, meaning that the problem exists in the task alert generation or reception.

Another problem has appeared, refered in https://e2e.ti.com/support/wireless_connectivity/bluetooth_low_energy/f/538/t/703914 .

Thanks

In scTaskAlertCallback() you enqueue a APP_MSG_SC_TASK_ALERT msg. Is this message ever handled, and if so, does it call processTaskAlert()?

I think you found the problem, but I could not solve it.

I did a less elegant solution and defined a new task in the main processor using the function ti_sysbios_knl_Task_sleep().
