I am using the DSPS as the basis for my app, on a Basic DK board. I have set #define CFG_EXT_SLEEP. When I do my systick interrupt never fires, which it does if CFG_EXT_SLEEP is not defined. The unit continues to advertise, when it does not have a BLE connection.
my questions are
1. Is the unit going into ext_sleep mode between advertisements?
2. If so, what is waking it up?
3. What current consumption should I expect when it is in this mode (no BLE connection), with the J-Link disconnected?
4. If it is not in ext_sleep mode, how can I make it do so?
Thanks for your help.

Hi c benson,
Yes in DSPS the da goes into extended sleep between advertising and connection intervals, the incoming BLE events (connection intervals or advertising events) is the event that wakes the device up. You can check for the current consumption in extended sleep mode in the FAQ section (while not connected it depends on the advertising interval). You can change the sleep mode from the da14580_config, there is no other option in the reference design for changing it. For more information for the dsps application you can have a look at this linkhttp://support.dialog-semiconductor.com/resource/um-b-038-user-manual-di....
