Other Parts Discussed in Thread: EK-TM4C1294XL, CC3200, CC2650

Hi, I want to use a 3G USB Dongle on my Tiva (EK-TM4C1294XL) using the Tiva as usb-host, to make like a bridge between ethernet and 3G
But I don't know where to start, I have been searching a lot but I couldn't find nothing like this

Regards,

Jaime

You will need to write a driver for the 3G dongle, the first step in writing this driver is to know what USB device class it is using

As you emphasize and/or promote, "Connect MORE" how do we do so w/the abandoned Cortex M3's (so unceremoniously dispatched) or w/new M7's - or very low cost M0's?

Might such severe, "limitation of choice" fly in the face of, "Connect more?"

The Connect More campaign is in relation to TI Wireless technologies (hence the wireless simple in the O of MORE)

And in that respect, if the M3 is your thing...you should check out the CC2650...An MCU that also has the choice of selecting BLE, 6LoWPAN or ZigBee. Also the CC3200 has a M3 core for the Wi-Fi subsystem, and M4 for the Host. I am feeling spoiled for choice.

Perhaps this is all a little off topic from the original post.

We note that the "missing" command cabin may have benefited had it been, "Connected more."

Hi

That's what I was doing, trying to make a driver, with a USB package analyser, I was seeing, what the dongle is sending and receiving to/from the computer.
So there is not a generic driver already made?

Jaime

No, there is not one available....do you know what USB Class the 3G dongle is using? Like the closest driver would be the one I developed for the CDC Class, which you can find here - github.com/.../tiva-c_usb_host_cdc_driver
