## Installation Issues

### I can install it - but when I send keystrokes nothing is appearing on the second device?

Try and go through these steps:

1. **Is your relaykeys stick properly attached?** Make sure the blue light is showing. If not you may have a loose connection somewhere. 
2. **Is it paired and connected?** - you will know this if the blue light is steady (*not* flashing) on the relaykeys stick
3. **check your COM port**. Lastly, it may be that the software cannot find the RelayKeys stick in its list of COM ports. [Read this guide](/products/relaykeys/developers/relaykeys-cfg.md#dev-defining-your-port-of-the-relaykeys-hardware) to configure and fix your COM port manually.
4. **Check your casing and spacing**. If you are using the command line applications, be careful - the application is case-sensitive. It should be *type:* and not *Type:* for example

### It was working all fine but now its not!

Is it paired and been shown to be connected with the receiving device? If so - and its still not sending text you may need to remove the Bluetooth AceRK device and then pair the AceRK again. To do this open RelayKeys-QT app on the sending device - click on "Add device" and then pair on the receiving device. 

### So I send LSHIFT,2 and I was expecting " but I get a @ - What gives?

Have a look at the [keyboard map.](https://docs.acecentre.org.uk/products/v/relaykeys/developers/reference-2#defining-a-keymap-c) You'll need to define/edit a keyboard map for the keyboard you are expecting it to be.
