Wireless Technology
VivaLNK Continues ECG Recorder uses Bluetooth Low Energy (LE) wireless technology (IEEE 802.15.1, managed by
Bluetooth Special Interest Group now) to transfer data between the ECG Recorder and the SDK, including ECG, RRI, HR, ACC data, and
device information, which complies with the BLE 4.0 and above.
Security Measures:
Low-power Bluetooth wireless communication between patch firmware and SDK, in line with Bluetooth 4.0+ low-power Bluetooth protocol,
works in the 2.4GHZ ISM radio frequency band, and belongs to general information technology equipment. Through security mechanism in
wireless Bluetooth communication protocol stack ensured by Bluetooth Special Interest Group, both patch firmware and SDK in APP are required
to execute these secure controls during data/information exchange. Additionally, AES128 encryption algorithm is added to encrypte the data in
the air during BLE transmission.
