Hey @hitheshkaranth,

The first step is to configure one or both UARTs on your chip to be available to user space apps. This is discussed here: [Need Information On UART](https://mangoh.discourse.group/t/need-information-on-uart/50/3).

I got tired of running these commands by hand all the time, so I built a small app to configure things for me: [https://github.com/brnkl/cf3-config](https://github.com/brnkl/cf3-config)

This app uses the same API (le\_tty) that you will need to communicate with your UART. In this app I use the device at `/dev/ttyAT` (the modem in the WP chip), but your UART device will show up as either `/dev/ttyHS0` or `/dev/ttyHSL` (UART1 and UART2, not certain which is which).

Hopefully this is helpful,  
Cheers!
