Bluesmirfs to connect two arduinos

Wireless & IoT
1

I am working on a senior design project at university. We are essentially building a remote controlled robot that can push along a wheelchair.

My current setup is the joystick shield over an arduino UNO, sending serial code for two PWM values to control two motors. This serial gets sent to another UNO that reads the two values, does some more processing for status LEDs, etc., then sends the PWM to our motor driver.

When I hardwire the Tx/Rx of each UNO to each other, my project works as intended.

We are trying to implement two Roving Networks Bluesmirf silver Bluetooth modules to replace the serial cable. They are not working.

What I’ve tried so far:

  1. CTS and PRTS are connected on each module.

  2. One is set to master, one to slave with auto pairing. They connect to each other within 1 second of powerup.

  3. Paired each individually with PC and monitored serial connection with arduinos serial monitor. Aka the modules do work.

Has anyone successfully communicated between two boards with these modems? Would appreciate some tips and advice.

Thanks in advance.
