mesh networking

[pavan]

Hello all,

Please let me know which module we can use for mesh networking for home automation project (lighting control through smartphone app),maximum how many devices we can connect in mesh network? and what should be the maximum distance between the each devices(node)?

Agree with Bjorn, you can use nRF51 and the nRF52 series to create the mesh networks.But, remember that not each module has a different network configuration, so not every device would connect to it. The above module series do support most of the devices, but it all depends on the hardware company.

The number of devices would depend on the mesh network- like for BlE Mesh network- you can connect up to 100 devices. But, Due to the absence of intelligent routing in most of the home automation protocols, there will be intensive server load. Of course, if you are working with fewer devices, then it wouldn't make much difference.
