CC2541: Advertising Beacon, Sleep Mode and battery life

$
0

Part Number:CC2541

We have a battery powered sensor based on TI CC2541 project code.   It is working however we are having a power management problem.\

What we want is for the CC2541 to wake up 1X per minute, broadcast a single BLE eddystone TLM packet and IMMEDIATELY go back to sleep.

Currently the device is sleeping for 59 seconds.  Using nRF Connect, we can see the correct beacon advertisement appearing 1X per minute. 

The issue is that the CC2541 is staying awake for 1 second before going back to sleep.  ~4-8 ma during this period.

This is probably a configuration issue.  Have been playing with moving 

 halSleep(DEFAULT_SLEEP_TIME);    and   osal_set_event( simpleBLEBroadcaster_TaskID, SBP_PERIODIC_EVT); to different places to see if we can get a shorter awake period.  No success.

Any guidance appreciated.

 Thanks
