Receiving simple message mesh

[Damien Berger]

Hi, 

I followed this thread (Link) to implement a simple message model on the light switch example from nRF SDK for Mesh v1.0.1. I created a "send_simple_message" function with all the given code that i call in a function called when a button is pushed on the client.

It seems the message is sent since i receive a "0" status after "access_model_publish". From the server, the led still change its state when i push the button; but i don't know how to read the message (and how to receive it).


Do i have to use the "simple_message_init" function and the others functions defined in the model, how to and when ?
Has somebody implemented the simple message model and could help me?

Thanks.

Sorry about that. This case did not show up in my list of unanswered cases unfortunately. The handle_incoming() function takes the message sent across the access layer & then handles the message depending on whether the mesh address is of type unicast or if it's a subscription address. I am also a bit unsure about the handle_incoming() function, but I have asked the mesh team that developed the sdk for help. I will update this comment as soon as I get a response from them.

Thank you, i understood how it works and i am now able to send and receive a simple message. I did not do the initializations, now it works and i am able to read the message in my server "main". Now i am trying to reverse the role, i suppose i have to implement a "simple message server" on the device that is actually the "simple message client" in order to be able to handle the incoming message correctly. Thanks for the help, i will come back if i face new issues.

Where should i need to write code for print incoming message and change in server main file. Can please share your server main.c file with me.

You have to use the "simple_message_server_init" defined in "simple_message_server.h" and the "access_model_subscription_list_alloc" as for the simple_on_off_server.
You should use the "LOG_LEVEL_DBG1" in order to see the opcodes received and sent:    "__LOG_INIT(LOG_SRC_APP | LOG_SRC_ACCESS, LOG_LEVEL_DBG1, LOG_CALLBACK_DEFAULT);"
If you receive the correct opcode on the server but the message is not handled, you should observe step by step the "handle_incoming" function in access.c

Tomorrow i will see if i can send you my files.
