[quote user="Vibhu"]So If I were to send command to 3 Servers via UART I would need 3 clients and totally 6 nodes in the mesh ?[/quote]

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

[quote user="Vibhu"]I have 5 nodes and is it possible to use UART and mesh at the same time in all the 5 nodes individually ?[/quote]

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

[quote user="Vibhu"]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 ?[/quote]

Yes, that is possible.

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.

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?

RE: Serial profile for mesh

Mttrinh — Thu, 25 Apr 2019 12:58:42 GMT

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.

I have 5 nrf52840 boards. All the boards have light server code. Now I have to turn on the LED on the 5th board which is not in range to my mobile app. But another one board is in range with my mobile app and that node is also in range with the 5th board. So will that board act as a relay node and re-transmit the command to the 5th board ?

Only is Coexist example the server only wont act as a mesh and work as a relay node ?

Or in client server example also If I have server code in 4 boards and wanted to do a generic on and off then also only server cant be used as a relay node in mesh ?

Sorry i'm not sure what you mean by this, could you eloborate/rephrase your question?

[quote user="Vibhu"]So if a mesh network communication needs a client-server then, the client only has UART, So I should send commands from UART to client and then send then to server using mesh ?[/quote]

Yes, that is correct.

[quote user="Vibhu"]If there are only 5 servers in a network wont it work as a mesh ?[/quote]

No, you will also need clients in the network to be able to communicate in the network.

[quote userid="15475" url="~/f/nordic-q-a/45480/serial-profile-for-mesh/181267"] Do you want to send a command from phone to node using UART, then transmit the command to another node via mesh[/quote]

Yes, I want to send command using UART and then transmit them via mesh.

So if a mesh network communication needs a client-server then, the client only has UART, So I should send commands from UART to client and then send then to server using mesh ?

[quote user="Vibhu"]So I send a command from my phone using the UART app and the mesh which is receiving should transmit the command to another controller via UART.[/quote]

I'm a little bit confused by this. Do you want to send a command from phone to node using UART, then transmit the command to another node via mesh? If so, yes you can use the UART Coexistence example to achieve this.

[quote user="Vibhu"]If I have 6 nordic boards with UART coexistence example in it, all 6 clients. Will I be able to send commands in UART to them and will that be also in a mesh ?[/quote]

All 6 clients can be in the same mesh network and you will be able to send commands to them over UART, but the commands won't be sent over mesh. A mesh network communicates via a client-server architecture, which means you need server models as well. You can read more about it here.

I want to use UART and mesh together in one node. I want to use UART to send commands to the node which should be in mesh network.

So I send a command from my phone using the UART app and the mesh which is receiving should transmit the command to another controller via UART.

The main use of UART is to send commands and the use of mesh is to increase the distance so that if a node is not in range I can communicate with it using other nodes.

Can this be achieved using the UART coexistence ?

If I have 6 nordic boards with UART coexistence example in it, all 6 clients. Will I be able to send commands in UART to them and will that be also in a mesh ?

[quote user="Vibhu"]Now if I send a command from UART app in phone to client it will turn on the LED in the Server right ?[/quote]

Yes, that is correct.

[quote user="Vibhu"]Will I be able to have as many clients as I want ? say 6 or 7?[/quote]

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

[quote user="Vibhu"][/quote]

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?

In the UART Coexistence example, I am using a phone as a provisioner and provisioned a Server and a Client.

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

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

My requirement is that I want to send a command to any particular node in the mesh using the UART.

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 ?

And by serial profile I meant the node should be detected in the UART app provided by nordic.

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?
