Huh? When there is misinformation about BT5, it is (of course) not intentional. Just journalists and bloggers extrapolating from partial information (e.g. press releases) and copying each other. The accurate and complete data is freely available on the Bluetooth SIG website (
there and
there). From those documents, it is clear that BT5 brings
many improvements, but all of them are for the Bluetooth LE (Low Energy) mode, currently not used by Hi-Fi audio streams. The only improvement that applies to the Bluetooth Classic mode (used by Hi-Fi audio streams) is the SAM (Slot Availability Mask) which improves the coexistence with LTE devices.
A quote from
a good article by Gary Sims:
- Bluetooth 5 extends and enhances the Bluetooth Low Energy aspects of Bluetooth, it does not alter Bluetooth Classic.
- BLE is not used for streaming audio to wireless speakers. This means that any notions of increased range or speed for audio streaming over Bluetooth BDR/EDR are wrong.
- Bluetooth 5 offers greater speed and distance for Bluetooth Low Energy connections but these are mutually exclusive, you either have greater speed or greater range, not both.
Radsone ES100 (same chipset as BTR3) became compliant with BT5 via firmware update, several months after its release. This is because Qualcomm made several versions of the base firmware (upon which manufacturers can build their own). As for BTR1K, its chipset is more recent, compliant with BT5 from the start.
