BT Mesh heartbeat issues in nrf52840

[shenghua]

Dear All:

I have followed the procedure as shown in the following to make a Mesh heartbeat application.  

I started with the example of ligtht switch client and server for SDK v.17.0.2/Mesh v.5.0.0. 

However, the server did not receive any heartbeat message from the client. I wonder if anyone can tell what the problem should be. 

We also use the nrf mesh app to provision the two mesh nodes as the follows.

The address of client is 0x0095 and The address of sever is 0x0098.

Then I configure the client with element and heartbeat parameters as shown below.

        

Then I configure the server with element and heartbeat parameters as shown below.

   

In the segger debug mode, at the server I did not find any heartbeat message received from the client.  

Best regards,

ShengHua

Hi,

It looks like all the screenshots show subscription, and no screenshot shows publication. In order for a node to send heartbeats, you should configure heartbeat publication, and make sure the count parameter for the publication is non-zero.

Dear Terje:

Sorry for late respones.

The screenshot for publication is as the following. How can we configure the heatbeat in the mesh client node?

Where we can find the sample codes for heartbeat message transmition? Thanks your help.

Hi Sheng-Hua

do you receive the messages in the nrf mesh app?
Maybe your subscription period is too low (in your setup the DK will listen for only 1 second on heartbeat messages). You could try setting the subscription period to a little higher value like for example 34 min 8 sec. Maybe you will see some messages. You can also click on refresh inside the to see if there are some messages.
Maybe you have a look here:

Dear Toni:

Sorry for late response.
After setting the hearbeat subscription for the server with unicast address:0x0098 and publish for client with unicast address: 0x0095,we don't receive the message in the nrf mesh app.
Then we tried to set the subcribe period to 2h:16 min as below and the server nodes still got no heartbeat response for the client nodes.

Is it neccessary to add the heartbeat_send() to enable heartbeat function in the light switch client?
How do we the function heartbeat_send() in the heartbeat.c or any suggestion for us?

Thanks your help.

Hi Sheng-Hua,

I am sorry, but as I am very new to Bluetooth Mesh and Nordic microcontrollers I can not really say much. 

I had the same issue but it is working for me. However I am not using the nrf Mesh SDK but the nrf Connect SDK.  Normally you don’t have to add the function heartbeat_send() function to see the heartbeat messages in the nrf Mesh App. But I can only say that for implementation made with the nrf Connect SDK. You could try setting up server and client light example from nrf Connect SDK and try out heartbeat functionally…

Best,

Toni
