I was able to get the GATT HealthRateMonitor sample code to work on an nRF51822 using an LG GPad F (Sprint's tablet). But when I loaded and ran the program BLE_Thermometer and connected I would get a message "The device does not have required services". Upon comparing the code for HRM with HTM, the #INCLUDE...for DeviceInformationService was NOT there plus any lines of code that reference that service was missing (because the code would compile). I inserted what I assume would be the correct lines and got the message to disappear but there doesn't seem to be any functionality. The graph display doesn't do anything. So the demo code is missing functionality. Is this what is called "Drive-by Coding"? It looks like Team BLE Low Energy FLAGGED this job and went on to their next platform. I'm hoping someone from the responsible parties will step up and address this issue.
