Fastrack Supreme GRPS multipoint connection


#1

Hi,

I’m a beginner with the Wavecom Modems. I have a working application between 2 Fastrack M1306B (master and remote 1) and Telemecanique PLC’s transmitting an analogue value in one direction by GPRS. Now I have to add another PLC+modem (remote 2) to transmit other analog value to the master.

In the master, the commands sent by the PLC are:
AT+CPIN=xxxx
AT+CGATT=1
AT#CONNECTIONSTART
AT#LTCPSTART

In the remote 1, the commands sent by the PLC are:
AT+CPIN=xxxx
AT+CGATT=1
AT#CONNECTIONSTART
AT#OTCP

I sent #VALL and both have the same #DNSSERV1, and #TCPSERV=255.255.255.255 (to accept all connections).

My questions:

Is possible to make this multipoint connection?
All must have the same #TCPSERV and #TCPPORT? And #PINGREMOTE?
What about #DLEMODE and #GPRSMODE?
Where I can find some info about the correct configuration of the Modems?
Do i need to perform some action with the plc in order to shutdown one tcp connection and start the other?

Hope you can understand me and give me some help

Regards
Alvaro
