HELP! RVR and Microbit Cannot connect to create Temp Sensor or remote Control driving

HELP! THE OCT. 2nd FOOD PANTRY FUNDRAISER IS IN TROUBLE!!!

Hello, I have completed multiple tutorials with the microbit and the rvr connections. I have checked data cables and read everything in the community files, youtube files, and websites. The mircobit cannot seem to connect to the rover to change led colors with temperature. If these two cannot talk to each other, I cannot have students build remote-controlled Microbit to have the rover play PAC-Man. Please note, we have tried the V1 as well as the V2 Microbits
Please help!!!

I have attached my block


code here.
Thanks, Anne Laughlin-Fuller
