EspruinoHub on an Odroid XU4

I like Odroids because they are fast and cheap, though not as cheap as the RPi. I mostly just followed the directions for installing the hub on a RPi. Everything was looking good on the XU4 but when I tried to start the hub I got a screen full of errors.

So I said 'ok', went and dusted off a RPi 2 and loaded everything up there. This time the startup was fine and the EspruinoHub was working fine.

Went back to the XU4 and looked at those errors again. Despite looking like a crash with a bunch of uncaught errors, the basic problem really was 'unable to connect to mqtt', and 'not authorized'. The problem was that unlike the RPi, the mosquitto server for Ubuntu by default does not allow anonymous connections. So I changed the config to allow anonymous and now the hub works perfectly.

Tl;Dr - EspruinoHub works great on Odroid and Ubuntu. Just need to allow anonymous to mosquitto

Great! Thanks for letting us know!

Any chance you could give us a Pull request on GitHub with a note about how to change the Mosquitto server's config?

I'm afraid I'm not much of a GitHub user. I have an account is about all. But in short (on Ubuntu) simply edit the file /etc/mosquitto/conf.d/local.conf and set allow_anonymous to true.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
