Wavecom GR64 Application Note - page 6

Overview
2.1 General
The remote script download is dependant on the currently active script within the
GR64 having the remote control (RC/IPRC) intrinsic function capability written in
such a way that once a connection is made (circuit switch data call or IP connection),
the remote control (RC/IPRC) intrinsic function is called and the remote script
download takes place. Once the script is downloaded into GR64 memory and all
checksums are verified, the GR64 is reset, and on completion of the power up
routine, the new downloaded script is activated.
It is imperative that the new script downloaded using the over the air routine also
has the RC/IPRC functionality written into it. If not, once this new script is activated
and running, this script cannot be updated again.
The remote download process takes care of script number allocation and will use
whatever script number is not being used by the activated script. This ensures that
the original script is not lost and can be activated again if the new script is not
functioning as expected.
Note: It is very important that the new script to be downloaded using the remote
download facility has been checked thoroughly for possible bugs or run time errors.
As once the script is downloaded and activated, it is not possible to gain remote
access again if the script has crashed and is not running.
2.2 Control PC setup
The user has two alternative methods available to assist in the remote download of
embedded application scripts. Firstly they can access the functionality via the
M2
m
power IDE (Directions for its use can be found in Appendix C), secondly the
user can use the Remote Download Application.
If using the Remote Download Application, the host PC requires Microsoft .NET
framework 2.0 to run the application. This Remote Download Application provides
connectivity to the remote module either through TCP/IP in the form of a host PC
Winsock or CSD using a GSM modem connected to a serial port. The Download
Sequence is as follows:
1. Select connection type, TCP/IP or CSD (serial).
2. Establish connection to remote module.
