4.2 Remote Update
The Apollo series support OTA field upgrades of the Apollo series resident application. An
over the air TFTP (Trivial File Transfer Protocol) connection is made over a UDP/IP connection.
A replacement file is then transferred from a server to the Apollo series and that file replaces
the previous application image.
4.2.1 Auto Execute
The Auto Execute Utility copies the contents of file system.exf into system executable RAM
and executes it from there. This file is the factory default application. Another file named
custom.exf can be loaded into the file system.
Auto Execute will look first for a file named update.exf and load and execute that in place of
custom.exf if it exists. If update.exf executes successfully, the previous copy of custom.exf is
deleted from the file system and update.exf is renamed to custom.exf.
4.3 Power Modes
The Apollo series devices support several power modes that are set by the power mode
command. In full power mode the cellular subsystem will maintain a persistent cellular
connection whenever service is available as well as an IP connection where available.
Any hardware or software reset will interrupt any power mode and return the device to full
power mode. In summary, the conditions permanently restoring full power mode include:
