At times, your device may require a critical update to radio firmware for devices connecting to the network. To stay compliant to Verizon’s LTE requirements you must implement FOTA. Failure to perform a critical update could result in losing access to the Verizon network.
MultiTech has developed a script for customers to use in order to initiate a FOTA update from the (the customer’s) local host processor (pull FOTA).
MultiTech LTE Category M1, Category 1, and Category 4 devices for Verizon, will allow the customer to initiate a FOTA update from a remote server (push FOTA) as required and communicated by Verizon.
If your device does not include local processing capabilities, you will be required to upgrade when that release becomes available.

and firmware build:
and wait for OK response (which indicates the file has been downloaded):
module has enough time to apply downloaded firmware. The time needed varies depending on the size of your firmware file.
in order to attempt to download and process the firmware file again.
- Before deploying the device, thoroughly test your chosen FOTA implementation for functionality.
- Before performing any module firmware update to devices in the field, first thoroughly test the new module firmware to ensure compatibility with your existing application.
- In the above example you might consider placing on the FTP server one file for every IMEI you deploy. Then have host application read module IMEI to determine which IMEI file on the FTP server to read. This would allow you to control which specific IMEIs you want to update by changing the contents of the file on server for the device IMEI.
