Currently, Bluetooth Low Energy (4.2) offers advertising packet sizes of 31 bytes and BLE 5 allows this to increase by a factor of eight, that is, the broadcasting capacity of a BLE 5 device would be 255 bytes.
To understand this better, let's perform a small experiment. In Chapter 5, Beacons with Raspberry Pi, we configured our Raspberry Pi to broadcast a URL as an Eddystone Beacon. We shall repeat the same experiment here, however, with a little twist.
In terms of the setup, this time, instead of the Raspberry Pi, we shall be configuring a MacBook Pro to broadcast the EddyStone Beacon.
