As devices get smarter and more regulated, it's becoming mandatory for manufacturers to deliver remote updates. Beyond satisfying legal requirements, regular remote updates also:
Remote updates delivered over wireless networks are called Over-the-Air (OTA) updates. These updates allow changes to be applied promptly, even for products that are hard to access. However, careful deployment is essential to security and user experience, so we offer development tools and customer support to help you set up OTA with confidence.
While there are various methods to implement OTA updates in your design, they generally follow a similar process. The execution of this process is primarily determined by the host microcontroller (MCU) in your design.
MCUs with integrated connectivity provide an all-in-one solution, making them the most direct option. You download your updates and apply them without additional wireless components. MCUs without connectivity can still perform OTA updates with the addition of a wireless companion device. Though this approach requires two components, it offers maximum flexibility since it works with any MCU.
OTA updates can also vary depending on what you choose to update: your application, device firmware or both. Whatever approach you take, you need a wireless device that delivers reliable connectivity to enable seamless updates.
Use the tabs to learn more about our OTA solutions and explore the resources available for implementation.
When it comes to OTA, using a wireless MCU as the primary processor in your design offers a complete solution. The MCU already has wireless connectivity, so you can easily download and apply updates.
Our newest wireless MCU families, the PIC32CX-BZ (Bluetooth and 802.15.4) and PIC32MZ-W1 (Wi-Fi), are designed to support OTA updates, ensuring that they are up-to-date and secure.
For MCUs without integrated connectivity, we offer a wide range of OTA-ready wireless companion devices, available in Bluetooth or Wi-Fi with various packages, to fit your design needs. Evaluate the OTA process in your design using our add-on development boards and easy-to-follow documentation.
In addition to completing OTA updates on host MCUs, our companion devices can also be used to update themselves. We have a wide range of OTA-ready wireless companion devices, including our popular plug-and-play products, to meet your needs. Try out the OTA process for yourself using our easy-to-follow documentation.
