hello everyone this is my first post, I'm mechatronics engineering student and I'm working on two arduino communication
modules using bluetooht
JY-MCU and want help to understand how to pair the two modules without needing a computer or cell phone if not arduino to arduino.
I hope can help me with this
Do you have a link to a datasheet for your hardware?
JY-MCU is what they call a linvor module on a 4-pin 5V header. That's what I have.
It depends what firmware you have as to how flexible the device is. HC-06 is the one I have, but get HC-06 if you can.
The user manual is here
or google for HC Serial Bluetooth Products User Instructional Manual
This chap tells you how to upgrade the firmware, but it looks a bit hairy to me!
One last thing: I found a much more useful utility to set up the adapter with AT commands than the putty or hyperterm route... it's calls sscom3e I think - it's covered in Korean writing, but it works quite reliably.
Good luck
