making an HTML page for receiving and displaying items using Web Bluetooth

this HTML page has to run offline i want to use JS for that which can use chrome to open the web app i am new to web bluetooth and i haven't been able to find resources to help me read strings off my bluetooth device

i know i have to setup SPP on the host controller then send strings when host is paired to client but on the application side the i am not able to try any simple solution there are limited number of bluetooth devices which can be connected to arduino and be configured to SPP
