I was just looking at doing the same thing using my verizon pantech usb modem... I started here.. http://finch.am/projects/arduinogsm/
In windows, I see the device has three comm ports..
PANTECH UMW190 Connection Port(COM8)
PANTECH UMW190 Diagnostic Port(COM6)
PANTECH UMW190 NMEA Port(COM7)
I've connected to the Connection Port using a terminal program at 57600baud and get an OK response with an AT command... But I cannot seem to actually get it to respond to anything but ERROR with any AT commands I issue (such as AT+CSQ)... Still looking into that..
EDIT:
Ok, so I didn't notice windows stuck a modem device on com5... So I was able to issue AT commands via that com port... Not sure how that translates to the MBED yet, but I am guessing there's going to be some interesting problems... I used portmon for windows to do some sniffing on how the verizon access manager talks to the modem but was unable to pull any intelligible information from it... =/
Hi, for the usb programming experts it would be realy nice for mbed to comunicate with a 3g usb dongle.
For example a popular usb 3g is huawei e220 that can be used in routers with usb port to give 3G/UMTS acess. (I have a fonera 2 n).
Is the configuration for the usb communication easy? So that mbed could send AT commands to the dongle
Best regards
