Update Your ESP32 Boards Over-the-Air (OTA) with Arduino Cloud

Update your ESP32 boards over-the-air (OTA) with Arduino Cloud

The latest version of the Arduino Cloud platform has enabled direct over-the-air updates (OTA) for ESP32 boards – a major capability that grants users the power to update their devices remotely. This functionality is especially important for IoT devices that require regular updates, as it allows changes and patches to be applied quickly and easily.

Before diving into the specifics of OTA updates, let’s take a look at what Arduino Cloud is, and why OTA updates are so important. Arduino Cloud is an end-to-end platform that enables users to deploy, monitor, and control connected devices quickly, easily, and securely. As the foundation of Arduino’s Internet of Things strategy, Cloud is the cornerstone of any user’s digital transformation, allowing them to bring physical products to life in the digital world.

What are OTA Updates?

OTA stands for “over-the-air,” and refers to a method of updating software wirelessly, without having to physically connect the device to a computer. OTA updates are common in consumer electronic devices, such as televisions or smartphones, where they allow users to update their devices rapidly and seamlessly. This same technology is now available for developers building IoT products with ESP32 boards, allowing them to update their devices’ firmware remotely.

With the latest release of Arduino Cloud, users can now perform direct OTA updates on their ESP32-based devices. This eliminates the need for USB cables and physical connections, and makes the process of updating devices faster and easier. It also allows developers to ensure their code is updated and running smoothly, even when their devices are deployed in the field.

How to Use OTA Updates with Arduino Cloud

Using OTA updates requires a few easy steps. First, you’ll need to setup your device in the Arduino Cloud platform. This includes creating a device type, setting up the security settings, and providing the device firmware. Once your device is configured, you can use the Arduino Cloud Dashboard to deploy your firmware over the air. You can also set up rules and triggers to automate the OTA process, allowing you to update your device regularly and with minimal effort.

And that’s it! With Arduino Cloud, you can now easily and securely update your ESP32-based devices over the air. This new feature makes the process of updating your device’s firmware much faster and easier, freeing you up to focus on developing your product instead of maintaining it.
