+The Android and iOS provisioning applications allow the user to configure the device manually or by scanning a QR code. QR codes can be generated by any online QR code generator. QR code payload is encoded with a JSON string containing the device name, proof-of-possession key (if used) and transport type (BLE or softAP), for example:
