You can take a look at our Heart Rate example (both peripheral and central).
The examples handles bonding, includes the battery service, and should be a good starting point for developing your application.
If you face any more specific problems, you are welcome to post another question and we are happy to help you.
Best regards.

I assume i will need to sleep the peripheral and wake periodically to save power. the application has a wall powered central that monitors an event. On an event it will tell three (typically) peripherals to activate a GPIO. Some time later they will deactivate. if the timer interval is the longest allowed lag between event and action, then I should be OK.

When peripheral wakes, it should advertise, be claimed by the paired central, connect. When the central connects, it can send any pending state change, then the peripheral can sleep again (as long as the GPIO stays high/low active).

solved - using mismatched softdevice and SDK

I had accidentally downloaded an antique SDK. I reinstalled S132 nRF52 SoftDevice 5.1.0 (production) SDK 14.2.0 www.segger.com/.../ Use nRFgo to program softdevice BLE-blinky worked right off

Next steps I need to do (and probably need help on) are:

Need to run and splice in SAADC code to monitor battery (or battery management?) Need to figure out how to publish battery state Need to optimize power consumption Need to figure out how to make the pairings persistent. (I unplugged and replugged the unit and my Galaxy still connects… maybe it is all set???)

Then the client...

Hi Jeff!

Take a look at this video, which is a part of our SEGGER Embedded Studio - Getting Started tutorial series on youtube.
At approximate 4.00 minutes, it explaines how to change the RAM START/SIZE values.

For creating your application, I suggest that you take a look at some of the examples in our SDK.
i.e the ble_app_blinky / saadc / ble_app_multilink_central examples.
If you face any specific problems, you are welcome to post another question here on devzone, and we will do our best to help you.

Best regards,
Joakim.
