Serial profile for mesh

[Vibhu]

Hi Guys,

I am using nordic nrf52840 DK.

Is serial profile and UART different ?

If so, what is serial profile in nordic and how can I integrate mesh and serial profile ?

I used UART example where I am able to send anything from UART app to the NRF52840,

I want to do the same thing with mesh also.

I want to send command like that to Mesh nodes also. Is it possible ?

How should I do it ?

I am using mesh V3.1.0

and sdk v15.2.0.

Thanks,

Vibhu.

Hi,

I think the UART Coexistence example is what you are looking for. This example let you simulate a button press over UART, and then sends a message to a mesh node. What do you mean by serial profile?

Now if I send a command from UART app in phone  to client it will turn on the LED in the Server right ?

 Yes, that is correct.

Vibhu said:

Will I be able to have as many clients as I want ? say 6 or 7?

Yes, you should be able to have that many clients in the mesh network.

Vibhu said:

If I have more than one client will that act as a mesh and if one client is not in range will multihop happen ?

Or only it can communicate to server ?

I'm not sure what you mean by this, can you elaborate?

Yes, it will re-transmit the command to the fifth board. But like I mentioned earlier, a mesh network communicates via a client-server architecture, so you will need client nodes as well.

Sorry, I am not able to understand. 

If it re-transmits to the fifth board, then from the fifth board I will send it to another controller so why would I need a client node for?

I might be misuderstanding, but you are using the Coexistence example, right? You want to send a command from a phone to a node via UART, then this node will send to another node in the mesh network, correct? If so, you would need a client to send a message to server in mesh network.

Phone-> Client-> Server.

So If I were to send command to 3 Servers via UART I would need 3 clients and totally 6 nodes in the mesh ?

I have 5 nodes and is it possible to use UART and mesh at the same time in all the 5 nodes individually ?

Like, if I want to send UART command from phone app to a particular node in any of the 5 I should be able to, Is that possible ?

You would only need one client to send a message to the servers in the mesh network.

Yes, you can run both UART and mesh in all the nodes.
