五、CSR mesh 总结 CSR’s Mesh protocol enables BLE devices not only to receive and act upon messages, but also to repeat those messages to surrounding devices thus extending the range of Bluetooth Smart and turning it into a mesh network. •The protocol encompasses different software models to support different end device types. •The concepts of device grouping, sub-grouping, association and device removal from a network are also supported. •It is possible to support up to 64K devices and 64K groups per network. • Devices may also belong to more than one network.
