Over-the-air (OTA) firmware updates
XLR PROs provide two methods of firmware update:
- Local firmware update via XCTU using the
- Over-the-air firmware update using the RF interface.
The over-the-air firmware update method provides a robust and versatile technique which can be tailored to many different networks and applications, with minimum disruption of normal network operations.
Over-the-air firmware updates can be sent to a remote node using a local node and XCTU, or an external application can be programmed to follow this process. There are three phases of the over-the-air update process: distributing the new application, verifying the new application, and installing the new application. In the following section, the node to be updated is referred to as the target node. The node providing the update information is referred to as the source node. In most applications, the source node is locally attached to a PC running update software.
