I recently got my Red Board Artemis (ATP) and could not resit but to check out the BLE LED example for the Arduino IDE. It worked out of the box.
For my project I need a RTC that is actually set to the real world time and I stumbled across the “Current Time Servie” (UUID: 0x1805) which apparently exposes the “Current Time” (UUID:0x2A2B) via the “nRF Connect” app. Unfortunately, I was not able to alter the BLE example (which documentation has to be read to find the descriptions of all functions that appear there?).
Nevertheless, if at some point a Current Time Service example would also appear it would help me to create a much more convenient project, which does not need to set time via buttons. And since time is often a part of Arduino projects it might help others as well (maybe leave a comment if you are also in need).
