Mesh networking is different. It lets devices talk to each other directly. This makes a network that can heal itself and get around problems.
Communication Protocols and Data Handling
The way devices talk to each other is also different. Old Bluetooth uses channels, while Mesh uses packets that can be sent by any device.
This way of sending messages makes sure they get through. But it takes a bit longer. Each device the message goes through adds a little delay, but it’s sure to get there.
Bluetooth 5.0 and Mesh Compatibility
Bluetooth Mesh works on its own, even with Bluetooth 5. It’s okay with Bluetooth Low Energy 4.0+ devices. But it doesn’t use Bluetooth 5’s long range or faster speeds.
This means mesh networks can’t use Bluetooth 5’s better range or speed. But they’re more reliable and cover more area.
Range Limitations and Performance Characteristics
Mesh networks have a big advantage when it comes to range. They can cover whole buildings, unlike old Bluetooth which only goes about 10 metres.
But, they don’t send data as fast. They’re about 1 Mbps, while old Bluetooth is 2-3 Mbps. This is okay for things like sensor data or control signals.
Mesh devices also use more power. They have to stay on to send messages. This is a problem for battery-powered devices. So, managing power is key.
