Nordic Semiconductor has shown Bluetooth High Data Throughput (HDT) running in silicon on video, one of the first demonstrations of a feature that, according to the company, nearly quadruples the maximum transfer speed of Bluetooth Low Energy without giving up its power efficiency. The Norwegian company announced it from Oslo on October 30, 2026, and will show the technology at electronica 2026 in Munich.
Nordic Semiconductor’s Bluetooth HDT in 30 seconds
- Nordic Semiconductor shows, in a video, Bluetooth HDT already implemented on a real chip, ahead of the specification’s publication.
- HDT nearly quadruples the maximum speed of Bluetooth Low Energy, according to the company.
- The Bluetooth SIG expects to publish the specification by the end of 2026.
- It works on top of the current BLE stack, so manufacturers will be able to reuse existing software and tools.
- Nordic will show it at the electronica 2026 trade fair in Munich, at booth C6 159.
According to Nordic’s press release, HDT adds support for larger packets and new ways to pack more data into each radio transmission. It builds on existing Bluetooth Low Energy (BLE) technology, so developers won’t need a new protocol stack, different tools, or a new vendor. The release gives no concrete speed figures in Mbps and doesn’t name the chip used in the demonstration.
What Bluetooth HDT is and when it’s coming
Bluetooth HDT is a feature currently in development within the Bluetooth Special Interest Group (SIG), the organization that manages the standard. Nordic says the SIG expects to launch it by the end of 2026, so this demonstration comes before the specification is published. It remains to be seen when compatible devices will reach the market.
The company, which specializes in low-power radio chips, is targeting the usual BLE product categories: wearables, smart home devices, PC accessories, and hearing aids. In all of these, BLE’s speed limit constrains features such as audio transfer, firmware updates, and sensor data syncing.
Why it matters for IoT
For anyone deploying connected IoT devices, the key point of the announcement is compatibility: if HDT arrives as an extension of BLE rather than as a brand-new technology, manufacturers will be able to reuse the code they already have. Nordic promises to offer HDT to its customers with the same software, the same tools, and the same development experience they use today, and has opened a page for designers to sign up at nordicsemi.com/BluetoothHDT.
Some questions remain that the release doesn’t answer: how much power a device will actually draw at maximum speed, which Nordic chips will support it, and how long it will take to show up in commercial products. The company will demonstrate it at electronica 2026, at booth C6 159.
Frequently asked questions
What is Bluetooth High Data Throughput (HDT)?
A Bluetooth feature currently in development that, according to Nordic Semiconductor, nearly quadruples the maximum speed of Bluetooth Low Energy while keeping its power efficiency.
When will Bluetooth HDT be available?
The Bluetooth SIG is expected to launch the specification by the end of 2026. Nordic hasn’t given a date for commercial products.
Do you need to change protocol stacks to use HDT?
No. According to Nordic, HDT is built on existing BLE technology and lets developers reuse their current software, tools, and protocol stacks.
Where can Nordic’s demonstration be seen?
At electronica 2026 in Munich, at booth C6 159, and in a video published by the company.
