I am assigned to use WebBluetooth functionality to connect to a Bluetooth BLE Printer and do some PRINTING.
Upon reading documentations, i figured that the way to do this is through some web bluetooth libraries that will enable you to CONNECT -> DISCOVER SERVICE -> DISCOVER CHARACTERISTIC and operate the manipulation on that.
My problem is to access these, in sample codes i see they put HEX characters for filtering.
My question now is, how do i know the CHARACTERISTICS UUIDs and SERVICE UUIDs on my BLE Printer so that i can control it to do some printing?
I would really appreciate any inputs regarding this.
