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.
Regards,
Daniel
