9.3 Bluetooth Communication
The PT900 system uses the Bluetooth protocol for communication between the
transmitter and the tablet. To protect the security of the product and the user data, a
proprietary protocol based on the common Bluetooth 4.0 protocol was developed.
For details of the Bluetooth communication mode, refer to
Bluetooth Spec 4.0.
Note: The PT900 transmitter does not automatically relink to a previously
paired tablet, and it does not automatically link to an unpaired tablet. You
must use the tablet APP to initiate the pairing of an unpaired transmitter.
However, the transmitter might still be paired with other tablets.
