Dear All,

Just wanted to check if the USB host stack available in MCUXpresso SDK supports 4G modem type devices. Also SFTP protocol as i don't see any SFTP protocol in lwip stack in the SDK.

Thanks

Babu

Thank you for contacting NXP support!

Are you using iMX8 or iMXRT?

Hi @sbabu,

The SFTP protocol is not supported. As for the 4G modem type devices, I believe it depend on the USB class type required for your modem. As long as it is a supported class, it should be OK.

BR,
Edwin.
