Using Bluetooth examples with Mbed online IDE

[ukBaz]

I am using the online compiler for the micro:bit at: https://ide.mbed.com/compiler/

I have the hello-world example working. However, I can't get any of the Bluetooth examples to compile.

I am focusing on the Eddystone UID example as I am hoping this is the more straightforward of the examples and have got the following error:

Any insight as to why this example isn't working straight out of the box?

Thanks,
