Data is not getting from sensor to Dashboard

Hello Experts,

I am following The simplest way to experience IoT in the HANA Cloud Platform - Part 2

I have following devices TI CC2650, iPad .Installed SensorTag & Evothings on iPad. Data captured from sensor is successfully displaying on browser as

below. As per above blog i downloaded simpleUI5dashboard & imported in SAP WebIDE .

Dashboard screen is attached below. Connection Dropped is showing at bottom of IoT Dashboard. Is anything i have missed ?
