Firmware update and restoration over AT-Commands (FOAT)
FOAT is a method to update the firmware by transferring the related file from an external device (e.g.application host processor) to the module through the AT interface. You can use the following applications, firmware and documentation to install new firmware on USB Connect LPWA:
Installation guide: SARA-R4 LEXI-R4 FW Update
Firmware installer: Easy Flash 13.03
Firmware: SARA-R410M-02B-04 IP FW package
Restore production configuration of the USB Connect LPWA
Unfortunately, the firmware update deletes all settings that are required to connect to the Vodafone network. These must therefore be restored. To do this, use the m-center Programme.
