Does Bluetooth use IP addresses?
Two examples of this today are Bluetooth and RFID. Your iPhone has an IP address; the Bluetooth speaker it connects to seldom does, since it is a Bluetooth link rather than an IP-to-IP connection that is needed for you to hear music. This is the secondary part, where the device contacting you needs an IP address.
What is master slave concept?
Master/slave is a model of communication for hardware devices where one device has a unidirectional control over one or more devices. In short, one is the master and the others are slaves to be controlled by the master.
What’s the difference between master and slave in Bluetooth?
Well, master/slave concept for Bluetooth resides on the protocol, not in the communications. On few words, this means Bluetooth Master is who has the ability to initiate connection with a peripheral (or slave), but onces connected both master and slave basically can interchange information without restriction (limited by application).
What are the roles of the BLE Bluetooth?
The roles of BLE Bluetooth are as follows: Advertise, Scanner, Slave, Master, Initiator, where the master is converted by the initiator and the scanner.
What is the difference between the Master Mode and the slave mode?
The difference between the master mode and the slave mode: The host refers to the party that can search for others and actively establish a connection. The slave can not establish a connection actively, and can only wait for others to connect with themselves.
How many slaves can be connected to an Arduino?
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.)
