Hi All,

   

I am pretty confused about the capability of BLE to build multihop (mesh, tree) network topology. At the beginning, I thought that it is the same with the classical bluetooth. And also, I see that there are some projects in 100_Projects_in_100_Days (e.g.            Day012_Central_Peripheral) mentioning about having multiple role in a node (I have not tried them out though). I thought that can be a way to build multihop topology. However, when I googled again for some basic information about BLE, some say it's not possible to have multihop topology but some say it is possible. Can anyone please explain about this? Or maybe give me some reference about it? Or maybe, if anyone has tried out the related projects or having other experience establishing multihop network. Please give me some guidelines. I would very appreciate it. Thank you.

Multi hop is possible either through advertisement channel (Bluetooth SIG is defining this protocol and Cypress recently made a press release that they support this feature) or through BLE connection (day 49 and Day 52 projects in 100 projects list).

   

I recommend to create a tech support case with Cypress.

Hi Undesh,

   

Can you send link to the project you are referring to ?

   

Multihop project any link would be helpful.

Here is the git page for all "100" projects; Day 49 and 52 are the ones to look at.

This project actually is flooding mesh. Here there is no fixed route. Our implementation looks as attached below. 

   

Any examples or suggestions to implement this ?

One of the "100 projects in 100 days" demonstrates a similar mesh-network setup, but I haven't done any ble meshing, so I don't have any good advice/help for that 😞

   

Creating a dynamically setup/routed mesh network is all software, and that is pretty hard even in wired circumstances.
