Bluetooth (4.1 LE) pairing for single and stereo FS-X speakers + battery level indicator
Bluetooth pairing for single and stereo FS-X speakers + battery level indicator
We’ve spent a lot of time doing hands-on pairing and stereo pairing, testing it with an array of Bluetooth devices (e.g. Macbook, iPhone 3S, iPad Mini, HTC One, Samsung Galaxy S3, etc.).
For the tech-minded, the implementation is now based on Bluetooth 4.1 LE.
The tests showed that our system is reliable, robust, and above all extremely simple i.e. intuitive, in fact, stereo pairing is automatic and the master and slave speakers identify themselves with different LED colours.
This is how our single button works for power on/off and pairing:
Single speaker operation
1. To power on, press the button for 2 sec.
2. When switched on, speaker will enter twin pairing mode for 10sec. Since there is only one speaker it will automatically change to single speaker pairing mode after 10 sec.
3. Your Bluetooth device finds the FS-X, makes it discoverable (as Frankenspiel FS-X) and you can pair it to your Bluetooth device in the normal way.
4. To power off the speaker, press the button for 3 sec.
Stereo Speaker operation
1. To power on, press the button on both speakers for 2 sec. Note: this doesn’t have to be done simultaneously.
2. Both speakers will then enter twin pairing mode for 10sec. Note: the pairing of master and slave is fully automatic, the LED on the slave will be a constant colour, and the LED on the master, instead, will be a flashing colour.
3. If these two speakers haven't been connected, each of the speakers will change to single speaker pairing mode.
4. Your Bluetooth finds the master FS-X speaker, makes it discoverable (as Frankenspiel FS-X) and you can pair it to your Bluetooth device in the normal way. Note: the flashing LED will become constant.
5. To power off the speaker, press the button for 3 sec. Note: you only need to do this on one of the speakers and the other one will automatically switch off.
Battery level indicator/warning
Here’s a snapshot of the new battery level indicator which will appear on your phone:
The battery indicator symbol is located next to the normal battery indicator of your phone (the example shown is on an iPhone).
In addition to this there is also an audible warning (beep) of low battery state which comes from the speaker.
We said we would also update on SPL this week, but we’ve overrun a bit on the issue.
We’ll update on that when we’ve done some more testing and can be totally sure of our data.
Enjoy the rest of your weekend!
