The Bluetooth device is discoverable for 1 minute after power on. The pairing procedure needs to be initiated by the end device. (e.g. mobile Android phone). Once the pairing was successful, it is always possible to re-connect with the Bluetooth device. The end application should be able to select the correct Bluetooth device when there are more than one paired Bluetooth devices available to connect to.
Depending on the type of end device it is or is not possible to have multiple Bluetooth connections. In most cases, there will be no problem with a Bluetooth car kit in combination with the Squarell Bluetooth device. After pairing the direct messages and the buffered messages are off and must be turned on by the receiving Bluetooth application.
