I need two Arduino units with the HC-06 Bluetooth board to communicate with each other and one of these Arduino units also connected to my Android phone. Is this possible to do with just two HC-06 modules, or even three? Or is there a better solution for this?
To reiterate what is going on here: I have two Arduinos that are running off battery. Arduino 1 is sending data every 0.5 seconds to the Arduino 2. Arduino 2 collects this, adds its own bit of data to it, and then sends this new data packet to my Android phone which will only be connected to Arduino 2.
I haven't completely decided upon what kind of Arduino board to get, but it needs to be fairly small, but I am planning on the Adafruit Pro-Trinket 5v.
Hopefully you get the basic scenario, let me know if you need more clarification and what you think could be done here.
Thanks a lot!
