Topic: Arduino Uno R3 + Bluetooth scanner (Read 1 time) previous topic - next topic


I am new to arduino world . I hope some can help me here!

I have a uno r3 and a ct20 bluetooth barcode scanner (http://www.amazon.com/CT-20-Portable-Wireless-Bluetooth-Barcode/dp/B00EYXQSVY) . this scanner works fine with PC/Android phones.

I wanted to read barcode using this one into arduino. So i bought a HC05 (zs-040). I followed instructions from the net to make the module as master using AT commands.

I set the password to 10010 (as the default password of the scanner) and then i set AT+init (for spp profile) and then i did at+link to add. but it appears it could not make a connection to the barcode scanner.

What am i doing wrong here? does HC 05 (zs-040) is not capable of connecting to BT scanners?

any recommendations?

Thanks a bunch for your help in advance.
