Hello:

 

I have been working with Lightweight Mesh stack for some time and I really like it.... Now, since BLE application space is growing, it would also be interesting if we could have the same mesh concept (using the routing that lightweight Mesh does) in BLE...

 

Would it be possible to use these concepts and have a BLE-based Mesh?

 

Thanks

Gus

Not is Bluetooth-compatible manner. If you look at Bluetooth radio as a generic transceiver, then it should be possible, but it will defeat the point, I think. And whether you can get access to a transceiver chip in this way is also questionable, they tend to be packed into modules with closed firmware and no documentation.

 

Some companies are claiming to have "BLE mesh", but it is a very limited range-extension at best and vaporware at worst.

IP will be in Bluetooth 4.2.

Nordic Semiconductor has a demonstration to lead-in to that; IIRC uses a Raspberry Pi to bridge Ethernet to Bluetooth 4 (a small USB dongle) then onto Nordic's Cortex-M0 Bluetooth 4 SoC.

IP is not mesh, quite the opposite.

IP to low power wireless - like 6LoWPAN - after address translation and header compression to fit the tiny frames in such wireless.. I'd say that calling it IP is a marketing ploy. It's really no different than a bridge/gateway from wireless XYZ to TCP/IP v 4 or v6.

HI.

 

I know this thread is bit old.But I have the same question. Are BLE stack and LWmesh compatible ? If not, Should we install stack separately on the µc for the Bluetooth ? I would like to add a BLE module and perform OTA to µc . Should the stack of LWmesh be used for the process?
