About microbit with Maqueen plus V1

I use microbit with maqueen plus robot V1. I have made the "follow the line " program and try to use the same microbit for sending temperature and light data to another microbit but it doesn't work in the simulation. Can you tell me why? This is the code I have created: https://makecode.microbit.org/S73912-93674-09920-11681 

Microbit firmware: V2.00

Thanks in advance N.
