Bluetooth Multiple Connections Solutions

Many people think that Bluetooth connection just have one-to-one connection, but one-to-one connection in many application scenarios cannot meet the requirements, these applications need multiple Bluetooth connections. Following as Feasycom’s multiple connections solutions .


1. Master/Slave multiple connections

The master pairs with the slaves one by one. Each connection will build a channel. The master can send data to each channel or receive data from each channel. Multiple connections cannot send data at the same time. In other words, the communication between them is not a throughput transmission mode, and it needs to communicate with different slaves at different times by sending instructions. The master-slave multi-connection is suitable for the construction of small-scale Piconet and Scatternet.

2. Bluetooth Mesh

Bluetooth Mesh provides many-to-many transmission between devices, and has the ability to build a large-scale network coverage. It uses network flood management technology. The data sent by a node will be forwarded by all nodes that support relay, but It will not be forwarded infinitely, and the node that has forwarded the data will no longer forward it. At the same time, Bluetooth Mesh has some special mechanisms, such as packet lifetime (Time To Live) management, which also effectively prevents unlimited forwarding of data. Bluetooth Mesh is suitable for IoT solutions that require tens of thousands of devices to transmit in a reliable and safe environment, such as building automation and wireless sensor networks.
