Help with a project

I was trying out a project from arduino website

But i am not able to get the communication between Arduino data and bolt module to get the messages working …
I get output if the python code as request was uncessful…Can someone guide me through this

First check whether ur ultrasonic sensor is working by using arduino and ultrasonic sensor only to verify if data is coming from ultrasonic then proceed further.

Hi, Can you check the Tx and Rx pin are connected perfectly? If connections are perfect then you can refer to this project.
