How to interface 4G LTE module to imx rt 1064

[vasudhevan]

Hi,

   Lwip stack support USB RNDIS mode.

   I checked with evkmimxrt1060_lwip_dhcp_usb_freertos demo code in imxrt 1064 connected to mobile using USB tethering method working fine.

  We have 4G LTE module it will support USB PPP mode, RNDIS mode.

  We want to connect this module to imxrt 1064 and we need to send some AT comment also through USB.

  How can we connect USB PPP , RNDIS mode ?

  This method will work with imx rt 1064 controller using lwip stack ?

Thanks & Regards

Hi,

We are able to get a working connection using a modified evkmimxrt1060_lwip_dhcp_usb_freertos example with Modem Quectel BG95 through the USB CDC interface.

We follow:

To establish PPPoS connection.

Regards.

Hi,

Unfortunately, we don't have related reference design and related software code.

I checked FORLINX Embedded company has related reference design,which using RT1050 with 4G LTE module.

Please check below link about detailed info (I couldn't find English version, the thread in Chinese)

Hi Vasu,

To be honest, we don't have application to use RT1064 with 4G module N720.

There with a document about using USB tethering host (RNDIS protocol) with MCUXpresso SDK and LWIP.

More detailed info, please check this link.

Customer could refer this document about using USB RNDIS with 4G module N720.

Thanks for the attention.

best regards,

Mike
