Modbus RTU to Bluetooth
modbus RTU to bluetooth converter

Hi all,

I want to control my modbus devices VIA bluetooth on my android device, but have been unable to find a simple cost effective converter to do this.

Any suggestions welcome.

You haven't specified which serial port the Modbus devices run on - RS-232? RS-485? Ethernet?
Assuming it's RS-485, TI has a chip for it, with firmware and Modbus app, so says the web page.

Not a recommendation from me, just a Google hit.
