Embedded applications controller mode

1 Introduction

The radio device, when powered up normally, will start up
the GSM signalling software and look to register with a
GSM network. The Embedded Application script runs as a
background process, as and when the GSM software is
idle. Controller Mode is a mode of operation whereby the
radio device powers up with a minimal subset of
functionality. The GSM signalling software is halted, and
the Embedded Applications script will effectively have
“control” of the processor.

Controller Mode allows an application to run with more
predictable response times. If the GSM functionality is not
required for a long period of time, but some periodic
monitoring of IO’s is required, Controller Mode can be
used, giving faster response, lower latency and a more
predictable execution time during Controller Mode,
causing the current drawn to maintain a consistent low
level without network dependent fluctuations.
