Hi @aykevl,

I've rewritten a bit on the nus console to work with serial port programs.
I added a few things, such as auto-reconnect, connect on name, connect on address, log to file, silent mode and listing of nearby NUS devices.

I also put the stdin in non-blocking mode and added disconnect detection, so that it is possible to exit the loop upon such event.

Also added a socat shell script to execute the pynus as a stdio program to the socat, to provide a serial device /dev/pts/X device.

Instead of creating a new fork of this, i'm pushing it back to your source. I'm hoping you are fine with this :)

Cheers!

Yeah, and i removed the replace(b'\n', b'\r\n') on the notification data as i'm fixing this in mainline. It turned out mp_hal_stdout_tx_strn_cooked in the ble_uart.c did not do what it was suppose to do.

I'm also curious, why you changed the RX/TX a few months ago... i turned them back to represent the function names seen from the Peripheral. Should i reshuffle them back?

Update pynus to work silent
7be532e 
Adding parameters to pynus to make it work silent by default.

New arguments:

-a/--address  - set the address of the device to connect to.
-n/--name     - set the name of the device to connect to.
-p/--print    - print a list of available NUS capable devices.
-r/-reconnect - Automatically reconnect to the device upon disconnect.
-l/--logging  - Logging to log file, pynus.py.
-v/--verbose  - Verbose logging to console.

Adding run_pty.sh script to run the pynus.py as uart backend for pty.
This pty instance can subsequently be used as a serial port to
communicate with the device. For example 'rshell' for micropython or
similar.
