Wireless connectivity roadmap
The current brochure specifies BLE 4.2. Bluetooth 5.0 is planned for a future hardware revision. The upgrade announcement also describes multiple Bluetooth 5.0 dongles for multi-device connections and synchronized acquisition. Applicable hardware, dongle configuration and synchronization conditions must be confirmed for the supplied version.
Upgrade descriptions follow the supplied manufacturer announcement. The amplifier description does not establish medical-device certification.
