3.4 Installing Updates

3.5 Verification and Rollback

Doing remote updates of IoT devices can be challenging. Care must be taken to manage all updates properly to ensure they go off without incident or disruptions.

Over-the-air (OTA) methods enable updates to be distributed automatically from a central platform to all connected things without physically accessing each device, significantly decreasing data usage and processing time.

Preparation

With IoT solutions becoming ever more critical to the success of businesses, businesses must develop ways to update them to remain secure and operational remotely. Unfortunately, this can be an extremely challenging task and presents numerous potential obstacles, such as setting up reliable connections with remote devices, dealing with software/firmware failures, handling technology obsolescence, etc. In this blog post, we will outline these common problems along with actionable solutions to overcome them.

Before updating their IoT devices remotely, companies should establish a testing and deployment system to ensure that updated IoT devices perform as intended and can be safely used in production environments. It would also be prudent to create a backup of current configuration files on each system so that it can easily be reversed if an update fails for any reason.

Please set up an effective process to enable IoT devices to receive updates to their firmware and software. This can be accomplished either using a gateway or downloading updates directly from the cloud – depending on their type and infrastructure supporting them, which may necessitate either option being chosen as appropriate; for example, low-powered sensors that lack strong embedded security may require having a gateway set up within their network as a safety measure against unauthorized access.

Update Distribution

At the core of IoT device updating is its distribution to individual devices. Updates may be distributed either physically or remotely. Physical IoT updates must typically be completed in person by an operator using JTAG programmers to gain entry into individual devices’ internal systems.

Physical updates of IoT devices are vulnerable to hacking and other security risks since their updates are open to anyone who wishes to take advantage of them. Remote updates, on the other hand, are handled through centralized gateways using CoAP (Constrained Application Protocol) or MQTT protocols tailored explicitly for resource-constrained IoT devices.

Over-the-air (OTA) updates provide another method for providing updates directly from a central gateway to an IoT device, providing patched software updates and adding new features quickly and efficiently. No matter which delivery or installation method is selected, documentation of delivery/installation steps must be kept so any issues can be identified quickly and addressed efficiently.

Backing up IoT device software can also be beneficial if an update fails during its installation process, providing a way to restore its previous state and avoiding downtime or other issues. This feature can prove particularly helpful when updating remotely via remote tools that need access to verify and deliver device updates.

Device Authorization and Authentication

Keep IoT devices up-to-date to protect their security and ensure their proper function. However, sending technicians out individually may be expensive and inconvenient for industrial uses such as agricultural sensors or automated cultivation machines. Remote updates provide an essential way to maintain their smooth running.

IoT updates can be delivered either over the Internet or radio communication, using either radio technology to manage large volumes of data or over-the-air updates using radio technology to manage large amounts of information, which are particularly effective for IoT devices that cannot connect directly to wired Internet access, such as field-based agricultural sensor systems that monitor soil moisture, meteorological conditions and automated irrigation machines.

These updates are typically distributed to IoT devices by a wireless network manager, such as an enterprise solutions provider. The network manager is responsible for providing and managing updates from legitimate sources and authenticating that they originated from them. This step prevents malicious attacks that attempt to downgrade IoT devices by installing older, insecure software or firmware versions onto them.

Software patches are another type of IoT update used to fix bugs or add features to an operating system. They follow the same process as complete OS upgrades but can be deployed more rapidly, with less disruption caused by IoT devices.

Installation

IoT devices must accept and install updates without interrupting their primary functions while simultaneously handling any problems or errors during installation. Failure of this process could damage or obliterate the device; to safeguard against such scenarios, an update process should back up the device configuration to recover quickly in case any problems arise.

Most companies must develop their updated backend infrastructure or partner with an outside service provider to keep devices up-to-date and ensure proper operations for themselves and their customers. Prioritizing updates, testing them thoroughly, and quickly deploying them without disrupting operations is often challenging.

An alternative approach for IoT updates could involve employing a cloud-based solution that allows companies to centrally manage and send updates directly to devices in their fleet of IoT devices, known as over-the-air updating (OTA), such as smart thermostats and industrial sensors in warehouses. OTA is ideal for large fleets as it eliminates manual, time-consuming, costly manual updates.

One alternative for over-the-air updates is using gateways connected directly to the Internet that send updates directly to IoT devices – known as E2G or edge-to-gateway-to-cloud updating; this method is commonly utilized by industrial IoT fleets that do not have full network access.

Verification and Rollback

Over time, IoT device manufacturers may release software and firmware updates that improve the functionality or performance of their devices. Staying current can allow users to take advantage of new features, reduce maintenance costs, and address security concerns and vulnerabilities more effectively. Unfortunately, not all update processes go as smoothly; poorly executed IoT updates may result in data loss or hardware failure; however, they can usually be reversed to a previous version if deployment attempts fail or corruption occurs during deployment.

Over-the-air (OTA) updates provide one of the easiest and safest methods of keeping IoT devices up-to-date, automatically providing software and hardware upgrades to devices using a central cloud platform that tracks them simultaneously. It makes the process faster and safer than manual methods, which require each device to be connected individually to a computer to download an upgrade and apply it manually.

Over-the-air updates (OTA updates) can significantly decrease the amount of data that must be transmitted to an IoT device by using compression algorithms that shrink file sizes and limit bandwidth usage, as well as being used to transfer multiple updates simultaneously to one device. Some OTA update methods, like package upgrades or delta upgrades, only change small portions of software on devices to reduce power consumption and transmission rates.
