I want to integrate a Luminary microcontroller with a 3G USB dongle.
Do all USB dongles support AT commands?
If not then what is the best way to do it?
Thanks..

Do you mean that you want to plug the 3G modem into the Luminary microcontroller? – user1725145 May 15 '13 at 08:14

yes plug 3G modem to USB socket, yet no plan to put RTOS on my microcontroller – user1729391 May 15 '13 at 08:25

What is the OS on the microcontroller? – user1725145 May 15 '13 at 08:54

Yes, you can expect that the 3G dongle will support AT commands. You need the modem (dongle) to make a modem port available, to which you can send AT commands. For this, you need a suitable driver, and maybe some software to convert the dongle from a USB mass storage device to a modem, depending upon your device. (When you first plug the modem in, it may be seen as a mass storage device, and must be converted to a modem) Ask the manufacturer for details, as this is not a standard procedure, and implementation is manufacturer specific.

Can u please elaborate what is the process or commands to convert mass storage device to modem, as there is no OS so can;t work on drivers. – user1729391 May 15 '13 at 09:21

Ask the manufacturer for details, as converting from mass storage to modem is not a standard procedure, and implementation is different for each manufacturer. Sorry, a microcontroller without OS is beyond my experience. – user1725145 May 15 '13 at 09:55
