Thanks for the reply...!
I am trying to run a simple sleep and wake up demo. Below are sequence of steps that I follow
1. Initialize sleep, GPIO pin and GPIO callback and comment out ble profile or connection related function(for this test) in app_create().
2. Put the radio to sleep / deep sleep in app_create()
3. Wake up the processor using external GPIO interrupt
The device fails to enter defined GPIO callback and neither goes to sleep again.
Is there a dependency of callback function to ble profile function?
Any info on using - "blecm_connectionEventNotifiationEnable" function.
I believe that i2c_temperature_sensor provides an example of this very thing.
