Solve Bluetooth connection issues

Case 1: I can't connect at all. 

1. Make sure the sensor is charged and can still charge, as indicated by the LED during charging.
   1. If the sensor doesn't charge and can't connect even though you recently used it, leave the sensor unplugged from power for at least 12 hours and try to charge it again. If it's still not charging, try the following: Battery charging guidelines

2. Place the sensor and mobile device relatively close together (less than 10 cm). If in doubt, let the sensor touch the device while the app is searching for it. It might be necessary to place the sensor very close to the upper part of the smartphone, especially with devices from Huawei, Samsung, or other brands.

3. Make sure that the device named "VMP" is not connected in the Android Bluetooth settings. If it is, disconnect it and ensure it does not reconnect.

4. Make sure that the app is allowed to access your "location services". This is necessary for a Bluetooth connection.

5. Make sure location services and/or GPS are activated.

6. If you still can't connect within the app, turn Bluetooth off and back on again.

7. If you still can't connect within the app, restart the device.

Case 2: The connection is broken or unstable.

Due to Bluetooth chips being mostly used in cheaper phones and tablets, some devices may not be able to connect to an Enode Sensor and a Bluetooth speaker/headphones simultaneously. Bluetooth devices that transmit sound tend to utilize up to 100% of the available bandwidth. Android, as an operating system, plays its part. A potential solution is to disconnect all other Bluetooth devices. Another option is to try connecting the speaker/headphones after initially connecting the Enode Sensor.
