This library replaces the previous BLE library. It is simpler to use and it is more powerful. Its API is based on B4i iBLE library which makes it easy to reuse B4i code.

but I didn't generate new UUIDs for the characteristics. What was wrong with the previous characteristic ids? Did they need to change? Did they change? As long as both sides of the BLE GATT connection agree on the ids, whatever they are, should all work fine. If not, then... nRF Connect app to the rescue! (as in: it can confirm that at least one side of the connection is working)....
