"UnaInside Mobile App is here for your operational teams to deploy and manage IoT devices developed by UnaBiz. UnaInisde supports Managed and Legacy protocols on devices. It includes a full range of commands such as device activation, trigger Sigfox downlink and Firmware Over-the-Air* for efficient on-the-field device deployment and management. Managed Protocol - uses UnaSecure, a proprietary encryption protocol developed by UnaBiz for NFC communications, so that all communications from and to the device are fully encrypted via UnaConnect. The fully integrated protocol also allows one click device activation. Legacy Protocol - uses standard NFC communication protocols with no encryption of the commands. The protocols are compatible with UnaInside and most iOS apps. A series of manual commands is required for device activation under the Legacy protocol. *Firmware-Over-The-Air is only available for supported devices using the Managed Protocol."
