Changing Between Demo Modes:
The Bluetooth specification requires the host platform (Phone or Tablet) to store information about a device
whenever it connects to it. Since the ID of the BT4 Eval board does not change despite which demo mode is
selected, you must clear this cached information from the tablet or phone if you wish for the board to be identified
as the correct type of device (Sensor or Beacon).
1.
To change demo modes, power down the board before changing the position of the Demo Mode selection
jumper.
2.
Clear the cached data on the phone or tablet by simply turning OFF the Bluetooth radio on the phone or
Tablet. This can be accomplished by the selecting the “Settings” icon - OR - on most Android devices, you
can quickly control the radios by swiping down from the top of the display to expose radio control icons.
3.
Repeat the demo instructions again as described above.
If the BT4 Eval board still is shown in the app as the previous demo device type (
“BT4Eval” or “BT4Uri”) and
therefore does not match your jumper selection, you may have to close the app and restart it. This may require
you to go into the Android Task Manager to shut down the application since it might be running in the background
even though you appear to have closed it.
