More human readable output for log streaming

[schlomo]

I'd like to use blew to stream logs from an ESP32 via BLE, e.g. like this:

❮ blew sub --name ESP32 --format utf8 6E400003-B5A3-F393-E0A9-E50E24DCCA9E
[01:02:21.344][D][zi
gbee:124][Zigbee_mai
n]: Receive Zigbee a
ction(0x1005) callba
ck

which works well, just that the lines don't break at the actual LF, which would make reading the output even easier.

That is actually the Nordic UART Service (NUS) which seems fairly wide spread for that sort of thing.

I think it would be nice to have a blew console --name ESP32 feature or something like that which could directly connect to such a NUS device and simply provide a console (bidirectional)

This is a great idea. I was actually considering adding a custom UART service command to support BLE UART, but let me see if I can add some format modifiers for now to allow for better output.
