Between two bluetooth devices to communicate, one should be a Master and opposite side
should be a Slave. In this case FB900AS’s operation mode is should be MODE1 to connect with
them.
Sometimes the bluetooth devices to connect with FB900AS are slave.
In this case FB900AS’s operation mode is should be MODE2 to connect with them.
Operation MODE1
There are two bluetooth devices to connect with FB900AS.
One is master mode and the other device is slave mode.
FB900AS’s operation mode should be MODE1 to connect with them.
If user wants to make the link chain with FB900AS, we recommend this mode.
