Can't find any (or correct amount of) devices. Instead got undefined on Raspberry Pi. #6

Hi @DylanPiercey,

as described on Twitter yesterday, I have issues getting results on my Raspberry Pi.

When I run arp -n I get the following 24 results. But running find(192.168.0.66) for instance returns undefined.

At the same time arp -n 192.168.0.66 returns something.

This is my demo snippet on the Pi:

const find = require('local-devices');
// Find all local network devices.

find().then(devices => {
  console.log('FIND ALL', devices);
})

// Find a single device by ip address.
find('192.168.0.66').then(device => {
  console.log('FIND ONE', device);
})

What am I missing? For the record, find() returns a list with 172 results (but I have only 24 devices in the network)

Thanks for your help!

My guess is the format for the command results is different between macOS and whichever OS you are using on the PI. Would accept a PR to account for this, the parsing of the results is happening here: https://github.com/DylanPiercey/local-devices/blob/master/index.js#L104

Do not currently have the time to dig into this, at least immediately.

Okay, I'll try to push something on the weekend or next week @DylanPiercey. Most likely I have some time. Let's see and thanks for the hint!

Hi @DylanPiercey, I am sorry I was not able to get back to you earlier. But I already started digging into the topic. During research I stumpled upon the following package and tried to adapt some of the parsing logic into your package. Let's see when I am able to get back to it.
