Bluetooth mesh Bluetooth mesh is a communication method that uses the mesh protocol based on classic Bluetooth.
Bluetooth mesh devices do not have subordination relations, and they communicate with each other in broadcast mode. For example, when a mobile phone on a Bluetooth mesh network sends an instruction, all Bluetooth mesh devices within 10 meters away from the mobile phone can receive the instruction and send it to other devices within 10 meters away from them. In this way, the complete instruction can eventually reach the destination or cannot be received. No partial data loss occurs. Theoretically, Bluetooth mesh supports more devices on a network than Wi-Fi.
Bluetooth mesh protocol The Bluetooth mesh protocol is a many-to-many (M2M) communication protocol based on Bluetooth. Devices that support the Bluetooth mesh protocol also support Bluetooth 4.0 and 5.0 protocols. Bluetooth mesh devices can communicate with other devices that support Bluetooth 4.0, such as mobile phones and computers.
Mesh parameters
