Why Sony uses Firmware-Over-The-Air (FOTA)
Since FOTA packages are pushed to the device, updates run unobtrusively in the background and do not require any intervention by the end users. Should they want to, service providers can request consent from users to download and install new software, but this is optional.
The combination of FOTA and always-on connectivity makes mSafety highly flexible. At the highest level, FOTA makes it easy to keep firmware up to date. This ensures the device is operating correctly and incorporates the latest security measures. Drill down, however, and FOTA opens up new opportunities.
For Sony partners who want to configure an application remotely without updating the software, mSafety offers a feature called Shadow as a complement to FOTA. Using Shadow, it’s possible to change how the software behaves, as opposed to changing the software itself.
This enables very specific and precisely targeted adaptations for certain user groups or even for individual users. For example, how frequently the device measures an individual patient’s heart rate can be adjusted, or a single trial participant can be reminded to take his or her medication.
