Recommended UART API

[Tim Adu]

Hi,

Our custom NRF52840 device uses a cellular modem. We communicate with this modem using AT commands.

We will also be hooking up our devices to a custom server that will push FOTA updates to our devices. 

I am aware of two UART api's on the NRF SDK - app_uart and nrf_serial.

Which one is more suitable for our use case?

Thanks,

Tim

Hello Tim,

I suggest you just use the app_uart. It is a simpler module, and I believe this would be well suited for what you describe here.
