how to send ATcommand to AR7550 when using Legato

The UART2 is used for linux console, how to send ATcommand to AR7550 when using Legato?

Hi,

You can do in the AR7 module through the Linux Console:

$ microcom /dev/ttyAT

Also, you can configure the usbmode in acm mode:

$ cat /etc/legato/usbmode
ecm
acm

Note: reboot the target after new usb configuration

Then, new /dev/ttyACM0 device will appear in your Linux host machine when you connect the USB.

Daniel
