I have been reading up about Bluetooth recently and I just want to know if it is correct to say that all Bluetooth 5.0 have the broadcasting feature? Is that the broadcasting feature also found in Bluetooth Mesh?
I assume you want to know about bluetooth low energy (BLE).
A broadcaster is a device that sends out advertising packets, but does not allow a connection from a central device. This is a basic feature that is part of all BLE versions.
Bluetooth Mesh is building on top of BLE and the broadcasting feature is not making much sense on this higher abstraction level. Although, technically, you can say that the broadcasting feature is part of Bluetooth Mesh.
