3G modem in USB host interface

Hi All,

I am want to connect Reliance usb modem with Sakura board. Anyone has idea, will it work, will modem get spoiled because of it?

Please share the code if you have anything related to it and idea regarding the same.

 

Thanks and Regards,

  • How are you doing this ?

    Are you connecting via USB ?

    via Wifi ?

    via Ethernet ?

    Please give a little more info ...

  • via USB

    SAKURA will be usb host device.

  • If you want to use GR-Sakura board as USB host, you need host side drivers for serial port of the usb modem you are going to connect. This will require lot of memory and the wrapper may to difficult to implement. One simple solution may be directly accessing the TTL serial pins in the modem using Renesas's UART peripheral. The modem's manufacturer may(not reliance) provide you the datasheet of commands. I am not sure if the usb host is capable to communicating directly with the modem. HID devices like pendrive may be easier to implement. Correct me if I am worng.
