FOTA Update Procedure for NL-SW-LTE-SVZM20
■This guide documents performing a Firmware Over the Air (FOTA) update for the NL-SW-LTE-SVZM20 Skywire modem using firmware files from an FTP or HTTP/S server and the modem's internal AT commands.
■The FOTA process is a device-initiated firmware update triggered by the host system. The Skywire will download the firmware file from the specified server and apply the update.
■The firmware files are only available to share under MNDA. If you do not have an MNDA in place with NimbeLink already.
■Section 2 provides information about NimbeLink-hosted firmware files (if any)
■Section 4 provides a generic example for using a HTTPS server, and the included URLs are for reference only.
■The modem cannot be powered down during the firmware download. Doing so will cause the download to fail, and the download will need to be restarted.
■Once the file is successfully downloaded, applying the firmware update will take around 200 seconds to complete. It is not recommended to power down the modem during this process. If the modem is powered down during this process the update process will pause and then resume once power is reapplied, but this is not recommended as URC notifications about the update may be missed, the firmware update may fail, and the modem will reset several times itself during the update process.
