Hi Satish,

My requirement is similar to yours. Need to send the information in beacon frames/advertisment in a mesh network to the main node with ble mesh & internet connection.

I am using nrf5SDKforMeshv300 SDK and PCA10040 boards. Flashed one board with beacon example, one board with light switch server example and other board with light switch provisioner example. I assume provision will acts as a relay and passes the data in mesh network.

I am unable to provision server & beacons with provisioner board. All the boards are placed at a distance & tx power of beacon is adjusted.

please let me know how you can provision? In some post i suggestions to modify light_server example to act as a beacon i.e need to port the code from beacon.

Regards,

Siva.

Hi beparas,

Did you succeed with your implementation,i'm also trying implement the same thing with nRF52832 DK board and nrf mesh sdk v2.2.0 (Beaconing example ) and nrf sdk 15.0.0 (ble_app_beacon example). i'm able to provision the beaconing nodes and scanning the ble_app_beacon device but i'm unable to send the beacon data to other nodes or hub in mesh packet. Can you guide me in how to send beacon data to other nodes in mesh packet?

Any help is appreciated, thanks in advance

Ok, then you need to study mesh. Please have a look here.

Hello Sir,

Thanks for great support.

Whenever my relay device received advertising packet, it will form mesh message containing,

1. RSSI of advertising device.

2. Address of advertising device.

& send this information to "hub" node.

So will you please guide me How to create mesh message & send it to "hub" node.

Thanks in advance.

Hi,

Is #1 a fixed requirement ? Can you simply broadcast your data as Mesh packet instead of BLE advertising packet ? If you can, then it's much more simple.

If you need to do BLE beaconing, it's could be a little bit more complex.

In our mesh beacon example, we do beaconing and scanning for beacon at the same time. However, there was not mechanism to send the scanned data back to one "hub" node. And you need to do it yourself.

But it can be a very simple mechanism, foe example whenever you receive any advertising packet on a node, you send the data to the hub address as a new mesh message. The relaying will be done as it's a mesh packet, and you don't have to worry about it.

As you don't provide much information about your application, we can't give you further advice on how you can improve the mechanism. For example you can add some filters, like only send the scanned advertising data when there is any change, or when the RSSI changes (when you do indoor locationing for example)
