How to send AT Commands from imx-rt 1064 to EC21-E Module

[JEGATHEES]

Hi 

I need to send AT Commands from imx-rt 1064 to the 4G module,

I tried the evkmimxrt1060_lwip_dhcp_usb_freertos sample code directly But it shows some makefile issue

Kindly Correct me if i am wrong

Hi @JEGATHEES ,

evkmimxrt1060_lwip_dhcp_usb_freertos is not designed to work with the EC21-E module, which interface of RT1060 is used to connect with this module? Please kindly clarify.

Have a great day,
Kan

Hi @JEGATHEES ,

Yes, RT1064 supports USB Host CDC application, you may use it to interface with EC21-E Module via USB VCOM port. please kindly refer to boards\evkmimxrt1064\usb_examples\usb_host_cdc\freertos\cm7\readme.pdf for more details.

Have a great day,
