7 essentials when implementing over- the-air (OTA) updates
Should it be IoTS? Best practice for OTA udpdates
When you have a small number of easily accessible IoT devices, updating the firmware or device configuration is possible with direct connections to the device but, as the number of IoT devices grows or are geographically dispersed, it becomes less feasible from a logistical and cost point of view to perform firmware updates in this fashion.
This is where Over the Air (OTA) updates become crucial. It enables devices to upgrade themselves when they are given information that a new firmware is available to download. Although this is not new to remote machines, more often we see devices that have been compromised due to poor security measures put in place during OTA upgrades or the device being bricked due to poor robustness procedures.
