@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.
So sorry that one of them died, that really should not happen. Please contact support for a replacement.
No, the battery in the Flic Single Series (Location, Music, Lights, Find, Camera) cannot be changed, however, it has a bigger battery than the original Flic, capable of sustaining for up to three years. This was a design choice we made in order to make the product at lower cost to allow for a lower price.
We made it so that it would not send an alert on single click because the high risk of sending false alerts. But thank you again for your feedback, we take it in and will reconsider.
If the connection is broken, you should not have to hold it down for 7 seconds, that only happens if your phone deletes the Bluetooth object from it's memory, or if you're using another phone. A single click will reestablish the connection, in fact, just being near it a few seconds will reestablish the connection.
11: Good point, we'll remove that in a future version of the app.
API: The Flic API is unfortunately not available for the Flic Singles. If you need flexibility, development options and removable battery, please consider using the original Flic instead of Flic Location.
