RTOS/CC2640R2F: Manual watchdog handling with BLE

Part Number:CC2640R2F

Tool/software:TI-RTOS

Hi,

I wondere if you could help me with a recommandation:

I have set up a watchdog for keeping my system alive in unforeseen events.

But due to a variable sleep period, I need to turn off the watchdog at certain points. I do this like this in the watchdog callback:

if(watchdogisenabledflag){

system_reset();

}

else{

Watchdog_clear(mywatchdog);

}

Watchdog is handled in my custom task by the watchdogisenabled flag turned on and off. (hope you get my point).

My question is:

How can I implement this watchdog for the BLE code, is it enough to enable flag in the entry of the simple_peripheral task for(;;)-loop, like this:

static void SimpleBLEPeripheral_taskFxn(UArg a0, UArg a1)
{
  // Initialize application
  SimpleBLEPeripheral_init();

  // Application main loop
  for (;;)
  {
watchdogisenabled = 1;
//all code that is happening
watchdogisenabled = 0;
  }
}

1. Is this necessary? Is there a risk for the BLE code hanging up on an assert or exception?

2. Is there a way to make the watchdog counter sleep when the system goes to sleep?

other comments are welcome as well,

BTW: basing my software on the simple_peripheral_oad_offchip code with SDK 1.40

Best regards,

Viggo
