GR4x to GR64 Migration Guide
3.4.1
Signal Behaviour
The LED interface (pin 33) power mode and network connection status indication
properties may differ to some degree from GR4x. The programming of this interface
will emulate, as close as possible, the existing indication.
3.4.2
AT Commands
The AT command set for the GR64 is similar to that of legacy products. Some
additions have been made to the overall command set. Changes and enhancements
have been made to some legacy AT commands which may result in slightly modified
behavior, or involve a different number or range of associated parameters.
The most commonly used legacy AT commands are provided in the table below,
which identifies difference that exist between the GR47/48 implementation and that
of the GR64. The table just provides summary information. Users are encouraged to
refer to the GR64 AT command manual for a comprehensive guide to command
parameters, usage and examples.
NOTE: The following table presents the most commonly used AT Commands and is
not a complete list. For an exhaustive list of all AT Commands available for the GR64
and their details, please refer to the latest AT Command Manual, available for
download on the Wavecom Web site.
