how to print the data from particular node to uart

[ps_anu]

hi...

i am working on mesh , i have done light switch example , now i want to get some message from node and send to particular node . how to print the same message which is from particular node to uart termite 

please help me out. 

thanks in advance

Which part are you stuck on:

1. Identifying which node sent a particular message?
2. How to print to the UART?

Each one is entirely independent of the other.

i am using two boards , example A and B .. A will sent a message to B And that message has to be read and write on uart using termite 

[ps_anu]

message_create(p_client, GENERIC_ONOFF_OPCODE_SET, (const uint8_t *) &p_client->msg_pkt.set,
server_msg_length, &p_client->access_message.message); in this case which paramater i should send message

If you are sending a generic on off set message, the set_params variable in generic_onoff_client_set(&m_clients[0], &set_params, &transition_params); will send the message data, which will send a bool value state. Like I have mentioned previously, one of the updates you will need to make is to change this bool value to a character string. The message_set_packet_create function takes the set_params variable & makes changes via call by reference to the first argument provided (i.e. &p_client->msg_pkt.set).

how to change the bool value to  a character string 

[awneil]

That's standard 'C' - nothing to do with Nordic.

A moment with google:

[Bjørn Kvaale]

ps_anu I did not mean to typecast the bool value to a character string, but instead of using bool on_off inside generic_onoff_set_params_t, you could use a fixed size variable e.g. char[3] msg

It should hopefully not be too hard to make the required changes required to send a message of a constant size over the mesh. You should also be able to provision & configure a custom model with nRF Mesh.

thank you so much...i have sent the message from client to server , now how can i print the data from server using uart

[awneil]

As far as the UART is concerned, it's just data - it is irrelevant where it came from, or how it got there.

Surely, you have used the UART before?

[ps_anu]

i hope, u didn't understand my question 

[awneil]

Then please clarify your question!

What have you tried?

Where are you stuck?

Have you tried SDK examples?

[ps_anu]

thank you so much Bjorn kvaale. i have set the message in generic_onoff_set_params_t, in light switch client example , i am getting results like what does it mean ?

 this is pic of client 

this is pic of server side 

how do i know my message have sent from client  to server and want to know whether it is received in server side or not
