The new ID will simply add a ‘B’ to the end of the 2015 Chromecast, becoming NC2-6A5B. With it, Google extends Bluetooth from low energy to full functionality. “New version contains same hardware as the original. Original version supports 2.4Ghz/5GHz and BLE radios. New version enables BT in the chip set so that it supports 2.4Ghz/5GHz/BLE and BT radios,” reads a report filing. “In this update, the new version will add BT functionality to Chromecast multimedia device.”
No Support for Original 2nd Gen Chromecasts
Though they contain the exact same hardware, original 2nd generation Chromecasts won’t be getting the extended Bluetooth functionality. Theoretically, Google can enable the feature with a simple software update, but it’s not that easy. According to the product attestation letter, the new Bluetooth mode requires a new equipment code. DSS or ‘Part 15 Spread Spectrum Transmitter’ certification wasn’t included in the original model, so Google is unable to enable it there. Due to the lack of a manual, it’s not completely clear what the new Bluetooth functionality enables. We’re hoping for controller, remote, or headphone support, but that would likely require developer intervention. Whatever the case, it will be interesting to watch the device’s progress.
