From what I understand the master has primary control over the slaves and communicates with them. A master must always be present as well, and can be connected to (up to) 7 slaves.
- If I have 2 arduinos with Bluetooth communicating with each other from within a radius of 80 meters or less, which arduino do I set as the master and which do I set as the slave? (what dictates which one should be set as master, etc.)
I want both arduinos to be able to transmit data to one-another (where neither has privilege over the other), so in my mind this is more like two slaves communicating. Both devices have the same controls on them and will effect the other devices the exact same way.
- How does the communication process work exactly, and how should more arduinos be addressed if they are to be added with similar privileges?
