What is the maximum transmission speed for Bluetooth devices?

The maximum transmission speed for Bluetooth devices, specifically referring to Bluetooth 2.0 + EDR (Enhanced Data Rate), is 3 Mbps. This version introduced significant improvements in data transfer rates over the earlier Bluetooth specifications, which had lower maximum speeds.

Bluetooth technology operates over short distances and has evolved over time, but the key to understanding its maximum speed lies in the version used. The Enhanced Data Rate of Bluetooth 2.0 improved upon the previous specifications, enabling faster data transmission, which was crucial for applications requiring higher bandwidth, such as audio streaming and file transfers.

Later versions of Bluetooth have increased speeds even further, but in the context of this question focusing on the specifications known around the time of Bluetooth 2.0, 3 Mbps is indeed accurate. Understanding these specifications helps in selecting the right Bluetooth devices depending on the data transfer needs in various applications.
