cc2538 zstack wake up from power save/low power modes -

Hariprasad C R

Other Parts Discussed in Thread: CC2538

1. Does using a timer for interrupt generation after a Xmillisec delay wakes up the zstack/cc2538 which is in low power mode ?

2. Does using osal_start_timerEx(); to generate a timed event wakes up the zstack/cc2538 which is in low power mode ?

3. Is the systick which is configured for 1ms, wakes up and checks the whether there is any event/ pending event ?

Thanks

osal_start_timerEx would create a delayed event which is count by timer interrupt and would be wake up from power saving mode after timeout.

It won't wake up every 1 ms. As I replied in previous post, it only wakes up after timeout of your delay parameter in osal_start_timerEX.
