Hi,

When I try to connect to the Espruino via Bluetooth, either from the Web IDE (on Mac) or BlueTerm on Android, I get an endless stream of error messages such as the following:

Most of it isn't even readable.

On the Web IDE, the status at the top never gets to Connected. It is stuck on Sent.

Any ideas? Possibly a bad soldering job?

Thanks

Have you tried just typing something in on the left of the WebIDE? While there is rubbish being sent it looks like there are communications with Espruino and it is responding.

The web ide saying 'sent' isn't necessarily a problem...

Yes, I've tried typing in commands on the left and even sending in commands from the right of the WebIDE, but nothing happens. Just a continuous stream of garbage.

I suppose it could be something to do with the soldering of the serial line going from the HC-05 to Espruino (so Espruino RX)... Maybe try resoldering the two wires marked with the red dots in the top-right of this picture:

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

> Quote text by starting lines with >

Mention another user by @username

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.
