The nRF9160 Feather comes with an on-board Silicon Labs CP2102 USB-to-UART chip. You can use it with most serial terminal viewers. If you have an older version of Windows you will have to install the driver. The download is located here.
Here's some recommendations for software to communicate with the nRF9160 Feather. No matter what program you use, the standard baud rate for the console is 115200. All other options are standard/default (8 bits, oon-pairty, 1 stop bit).
CoolTerm has been my go-to for testing and debugging. Fortunately it's also multi-platform! You can download it by going here: https://www.freeware.the-meiers.org
You can use
screen to view your debug output. Here's a typical command:
screen /dev/tty.SLAB_USBtoUART 115200
The major drawback of using
screen is that it does not save your history. It's better to use other utilities for that purpose.
Note: depending on your system your serial port may be named something different from
/dev/tty.SLAB_USBtoUART. You can check your dev folder like this to check which one may be it:
ls -l /dev | grep SLAB
You can also use
cu to display your debug output. Here's an example:
sudo cu -l /dev/tty.SLAB_USBtoUART -s 115200
If you notice, it requires super user permissions. (This is the only drawback to it IMHO)
