Why is my BLUETOOTH(R) connection slow?

• Data transfer speed depends on obstructions and/or the distance between the two devices, radio wave quality, and the device configuration or software in use.
  Move your VAIO computer and BLUETOOTH device closer to each other.

• If a version of a BLUETOOTH standard employed on the BLUETOOTH device with which you want to communicate is not the same version as the one employed on your VAIO computer, the communication speed may become slower.

• When your VAIO computer is equipped with BLUETOOTH Core Specification Version 2.1 + EDR, if both the BLUETOOTH function and the wireless LAN function are enabled, interference may occur resulting in slower communication speed or other problems.

• If the BLUETOOTH device with which you want to communicate supports only BLUETOOTH low energy technology, the maximum communication speed is limited to the one for the low energy technology.

• If your VAIO computer is compliant with BLUETOOTH high speed technology and the following two conditions are met, high-speed communications are available. However, some BLUETOOTH profiles do not support high-speed communications.

• The BLUETOOTH device with which you want to communicate supports BLUETOOTH high speed technology.

• Both the wireless LAN and BLUETOOTH functions on the computer are enabled.
