@joacim thanks for your reply. What you say makes sense since the smartphone manufacturer normally will not expect many concurrent Bluetooth connections to the phone. The RPi can support 10 concurrent connections so I will be using that.
Your IFTTT integration is horrible. Just simple IFTTT actions (do x when I double click button) takes up to an hour to work IF it works at all. I'm having to leave Flic, unfortunately because of the mess. Even the IFTTT recipes show it SHOULD work within an hour
.. AN HOUR. So disappointed. Notice the one hour message in IFTTT in pic attached.!0_1506228779054_Screenshot_20170923-195029.png
