3.2.3 Internet Method
Points to be Considered
Internet Method of Firmware Upgrade is applicable for release
9018 / 9019 and beyond.
Internet Method of Firmware upgrade has two parts
o Libre Application Firmware
o GCAST Firmware
Updating LS-Application Firmware (83_IMAGE_network) is
mandatory in internet method of firmware upgrade process.
HOST-MCU firmware can be updated only along with the LS-
Application firmware. Independent update of HOST-MCU firmware
is not allowed.
GCast firmware update takes place automatically whenever there
is any update from Google server. After successful update, LS
module will send reboot command to Host-MCU. It’s up to Host-
MCU to reboot whenever required.
