For this project will use the Microchip USB host driver. To get it to work, need to create new driver to first switch to USB modem mode, setup the endpoints to transfer the AT command to the endpoints.
Try to send some AT commands.
so far so good!
Next will pop in a valid SIM Card and check if I could send and receive SMS using PIC24FJ256GB106 with a TP Link MA180 USB 3G Modem.
