Hi forum,

I am trying to send SMS via the USB huawei dongle through the lpc1769. How do I go about doing this. Could someone point me in the right direction?

Should I use the USB Host Lite on the LPC1769 or by using a FTDI RS232 to UART, try to use UART to communicate with the USB dongle to send the SMS. I am not sure which one would work, just some ideas that I have gotten while searching the web for a solution.

Regards
Joe

Well, if this Huawai dongle is a 3G module with USB connector then you normally need to operate it on a computer and not on a microcontroller.
If it's a special type of dongle providing you with an AT command interface (e.g. UART with 115kbaud), then simply use one of the UARTs of the LPC1769.
If the dongle gives you a virtual COM port then you need to run a USB host software on the LPC1769 which implements this profile.
