I want to do a project with an Arduino Uno and two other BLE (or regular bluetooth) capable modules. I want the Bluetooth modules to be hooked up to buttons (one button for each Bluetooth module). I then want the Bluetooth-capable modules to send the state of their buttons to a central Arduino board.
Is this possible? Can I have two different BLE boards connected to one Arduino?
I have a RedBear BLE (Bluetooth low energy) shield for my Arduino. What micro-controllers should I get for the peripheral modules? And where can I learn about pairing Bluetooth modules? Everything I read seems to be about pairing Bluetooth boards to a phone.
Can I do this all with BLE or am I going to need to get a new shield for my Arduino to talk with the two peripheral boards?
