Dear All,
I dont understood exactly:
to solve communication problem I made several steps ahead
Reset CR-1000 Data logger OS
set up interface SC105
and reconfigure modem fastract xtend with AT commands
and I inserted dataSim with Static IP
In PPP connection where logger reported IP address of the local provider I can see dynamic IP address. Each time when i remove sim card from the modem and inserted it back to the modem the new IP address appeared.
ppp state: daled -> IP Opened
PPP is Default Network
IP: 10.76.177.184
gw: 192.168.111.111
from here I understood so, if I can see this dynamic IP address, it is mean that I was able to establish comunication, between logger, interface and modem.
second:
I sent all these AT commands(see below) to the modem via terminal and response was ok for all of them.
including:
AT+CFUN=1 Confirms that the APN domain is verified.
AT+CGDCONT? Verify modem configuration
But I read manual:
(In addition you need to program the modem with its APN server setting. This is
the server it logs into to gain access to network services. This involves issuing the
following command to the modem, where the server name is as specified by your
provider:
AT+CGDCONT=1,”IP”,”servername”
For example for O2 enter: AT+CGDCONT=1,”IP”,”mobile.o2.co.uk”)
and I have got this message from aps:
The APN setting normally needs to be set in the modem separately using a terminal emulator and by sending AT commands,, unless you embed the setting into the dial string which is not normally advised. Normally you will leave the IP address in the PPP screen at 0.0.0.0 which instructs the modem to pick up the address from the network. You should only set a fixed address if specifically told to by your network provider, i.e. to try to force the fixed IP address in the modem.With the 0.0.0.0 settings the logger will report the IP address it is assigned in the PPP Network Status box once it has connected to the network.
Now i think so, i need to send to the modem this settings: AT+CGDCONT=1," My ststic IP address "," Pro or Azercell internet";ATD*99***1#
Am I right here or not?
the AT commands, which I sent to the modem in the below.
Can someone check and give me own opinion. Are these AT commands are suitable for configuration modem for GPRS or need set other comands like: (AT+CGDCONT=1)
AT
AT&F
AT+IPR=115200;&W
AT+WOPEN=0
ATE1
ATX0
ATS0=1
AT&D2
AT+CICB=0
AT+IFC=0,0
AT+WIND=0
AT+WRST=0
AT&W
AT+CFUN=1
AT+CGDCONT?
AT&V
