-BLE mesh protocol
1. Data can be sent from any node to the entire network, realizing the powerful function of controlling the entire network from any node.
2. Self-organizing network, large number of nodes, and strong anti-interference all make BLE mesh to be the most popular solution in the smart lighting control.
-The feature of BLE mesh
a large amount of nodes, the MAX capacity node is 32,767
Lower cost, no need router and coordinator
Much more compatible, the normal smart phone with bluetooth
BLE NRF52 series can be used in BLE mesh well
-96 dBm Sensitivity in the low energy consumption mode
To Support 1 Mbps、2 Mbps data rate
TX power: -20～+4 dBm
The peak current of TX is 5.3 mA in 0 dBm
The peak current of RX is 5.4mA
RSSI ( 1dB resolution)

-BLE mesh application diagram
-Function expanding combine BLE mesh and BLE beacon
- To control lighting A,B,C,D,E,F by BLE mesh via cellphone
- To control all lighting by bluetooth gateway via cellphone
- Each lighting can be replaced by ibeacon, pop-up ads，indoor positioning etc.
- To control all lighting by the sensor、PIR
