OS updates made simple
Providing Android (F)OTA updates throughout the lifecycle of an embedded device poses a substantial challenge for businesses. Modern digital products require regular updates on a regular basis. They should include:
- Latest security patches
- Critical bug fixes
- Functionality upgrades
- Added business services
With emteria, all software changes and regular security updates will be evaluated, built and delivered to your devices automatically based on your maintenance schedule and specific product requirements.
Why are Over-The-Air software updates important?
Protect against threats
Install essential security patches, bug fixes, and latest improvements just a few clicks.
Comply with legislation

Distribute updates directly from your browser
The Device Hub is a powerful cloud platform that makes the preparation, delivery and management of Android OTA updates for developers and product managers easier.
The cloud infrastructure comes with an automatic CI/CD pipeline for the AOSP to build, sign and upload new releases to emteria's secure (F)OTA servers. From there, you are able to distribute your IoT OTA updates manually or automatically based on your specific schedule or respective group configuration.


Make use of secure update delivery
Keeping security standards high is one of emteria's top priorities. In addition to custom signing certificates used for protecting the final Android OS image, emteria also performs integrity and consistency monitoring for all releases stored on emteria servers.
Each (F)OTA Android package is downloaded via encrypted connection and validated one more time before the OS update is installed on the device. This process guarantees that binary files have not been compromised during data transmission. To allow rapid testing and feature development, while preserving the stability of production systems, emteria offers dedicated release channels for all (F)OTA releases.
