BLE mesh network...

[Prasad Dabak]

Hello,

I am wondering if you have any plans for implementing a Softdevice that supports BLE mesh network on nRF52832 in near future?

If not, if I were to implement it myself, is Softdevice S132 sufficient for me so that I can implement a mesh on top of this? Can this device act as peripheral to one and central to others at the same time?

Any advice/pointers will be greatly appreciated.

Thanks. -Prasad

Yes, i think it's absolutely possible to implement a mesh network with SoftDevice S132 but in the past, in my business, we have implemented a very simple mesh topology using BLE connectionless systems, like advertising. Just for hint, you can, for example, use Manufacturer Custom Data fields of advertising packet to send your message using a simple header to notify receivers if message was fragmented, the message len etc...

Obviously BLE connectionless systems does not allow to transfer a big amount of data, but if your goal is to send small data (up to 50-60 bytes, for example) i think that advertising is good enough.

I second on this, you can use S132 to have upto 8 connections, it is definitely possible to create mesh topology with it.

Hi Prasad,

nRF52 support for the nRF OpenMesh is underway, but I don't have an ETA on the release.

Have a look at fruitymesh, which I created: github.com/.../fruitymesh

I have had it run on an nrf52 and there should be little changes needed for it to run on the nRF52 in its current state. It can be compiled with the latest SDK.

Thanks a lot to all for providing your valuable inputs/pointers!
