Bluetooth Specifications

Bluetooth support with our wireless adapter is dictated primarily by the operating system, i.e., Microsoft Windows or Linux.

Our wireless adapter Bluetooth specifications are as follows:

  • The 1525, 1535, and 1435 support Bluetooth 4.2
  • The 1550, including the 1550i and 1550s, support Bluetooth 5.0

However, as the Bluetooth stack in your operating system ultimately dictates what is and is not supported for end-use, you will be limited by the following Windows 10 specifications if you are using Windows 10:

  • Windows 10 does not support Bluetooth 4.2. It only supports Bluetooth 4.1, and this is mostly inconsequential as PCs do not use most Bluetooth 4.2 features.
  • Windows 10 supports A2DP but does not support A2DP sink which means that, although you will be able to stream from your Windows 10 PC to a Bluetooth device, you will not be able to stream from a Bluetooth device to your Windows 10 PC. 
  • Windows 10 does not support +HS profiles, which means that transfer speeds, even with Bluetooth 5.0 devices, are limited to a maximum of 2 Mbps.

For faster transfer speeds, Wi-Fi Direct may be a good alternative. You will need to refer to your device’s support for instructions on how to connect using Wi-Fi Direct if supported.

Although we do not directly support Linux, many Linux distributions offer more comprehensive support of both Bluetooth 4.2 and Bluetooth 5.0.

Windows 7 supports a maximum of Bluetooth 2.1, but the Bluetooth standard allows for backward compatibility, enabling the 1525, 1435, and 1535 to work with Windows 7.

Windows 8.1 supports a maximum of Bluetooth 4.0.

Bluetooth audio codecs supported include only those that Windows natively supports. Our adapters do not support LDAC or aptX. AAC is supported natively by Windows.
