I want to use my own BlueTooth receiver for the Xbus Master.

When using the Wireless Receiver (WR-A), make sure that no other bluetooth device is active! Especially make sure that devices that were previously used with the Xbus Master (XM) are turned off. The XM can be configured to communicate with a third party bluetooth device BT1 by initiating the connection from BT1. Afterwards, the XM will look for BT1 on start-up, to make a connection and to send data.

The WR-A, once configured to link with a specific XM, will attempt to connect to that XM. However, if the XM is already connecting to BT1 because that was its last known link partner, the WR-A will be ignored. Only if BT1 is inactive and cannot be found by the XM, will the XM respond to other devices initiating a connection - for example the WR-A. Of course, the same is true the other way around, if the last link partner was the WR-A and that is active, it will not be possible to let the XM talk to BT1 until the WR-A is turned off.
