Bluetooth scanner with normal phones

I have a Zebra Bluetooth scanner- RS507X.
I want this scanner to connect to my normal android phone and provide the scanned data.
The documentation that I found on the website uses EMDK, and the android phones do not support that.

Is there a way we can achieve this without using EMDK?


How to get battery status via Bluetooth (ZQ320, Android)?

I'm trying to get battery status via bluetooth connection for mobile printer ZQ320.

DS3678 to STB3678 bluetooth connection

Hey Everyone,

It appears our Zebra DS3678 devices are losing connection / pairing to the bases (STB3678) that hookup to various machines to read data--the only way of re-establishing this connection is for our devices to be power cycled. These devices have been used for the last couple years. Has there been any reported issues these kind of symptoms?

Attempting to diagnose if this is a end user operating issue or hardware problem.
