Hi Johan,
I understand basics on configuration model. However, I'm trying to add app key, it results in following error

unable to send App Key add (error -11).

I face same issue trying to add net key. For your reference, I'm attaching snapshot of mesh shell

Are there any specific commands you're wondering about? You can get the
full list of them by typing "help". You'd e.g. start with provisioning
by typing "provision <network index> <unicast address>". The shell does
require basic knowledge of the configuration model, so I hope you can
explore the available commands and by experimenting get something
working. Each configuration model related shell command maps directly to
a configuration model message, so you'll need to look at the respective
specification section for each command for the details of its
parameters, etc.

Zephyr does not yet have provisioner support. You can only provision the
local node throught the mesh shell at the moment (since that does not
involve running the full provisioning protocol).

There isn’t a heartbeat subscribe command in meshctl. It wouldn’t be hard to add. Take a look at the code and add it. I’m on vacation for a couple of weeks

I don't think meshctl has this support yet. IIRC, Steve sent an RFC
patch for that, but nothing has been merged upstream yet.

I've enable CONFIG_BT_MESH_CFG_CLI=y this in prj.conf

Added "Configuration Client Model" into list of models supported by
root_model -->

static struct bt_mesh_cfg_cli cfg_cli = {
};


static struct bt_mesh_model root_models[] = {
BT_MESH_MODEL_CFG_SRV(&cfg_srv),
BT_MESH_MODEL_CFG_CLI(&cfg_cli),
BT_MESH_MODEL_HEALTH_SRV(&health_srv, &health_pub),
BT_MESH_MODEL(BT_MESH_MODEL_ID_GEN_ONOFF_SRV, gen_onoff_op,
&gen_onoff_pub, NULL),
BT_MESH_MODEL(BT_MESH_MODEL_ID_GEN_LEVEL_SRV, gen_level_op,
&gen_level_pub, NULL),
BT_MESH_MODEL(BT_MESH_MODEL_ID_GEN_ONOFF_CLI, gen_onoff_cli_op,
&gen_onoff_cli_pub, NULL),
};
That all looks fine to me, however note that you don't need this if
you're planning to use an external tool like meshctl.
CONFIG_BT_MESH_CFG_CLI is only needed if you want to use Zephyr as the
configuration client.

One thing I forgot to mention: you can play with most of these features
also using tests/bluetooth/mesh_shell. It has commands for configuring
heartbeat publication & subscription. The commands aren't exactly the
same as meshctl, so be sure to check with "help" for what commands are
available and what parameters they take. The mesh shell uses internally
the same configuration client API that e.g. bt_mesh_cfg_hb_sub_set() is
a part of, so if you're interested in more examples of this API's usage,
take a look at subsys/bluetooth/host/mesh/shell.c.

The call to bt_mesh_cfg_hb_sub_set() that you found in mesh_demo is on
the right track. It will send the heartbeat subscription configuration

mcuboot usage guide

Hello experts,

 

The Zephyr(v1.10) project has run in my NRF52_PCA10040 board.

Mcuboot source code has been downloaded.

But Zephyr and mcuboot sites give very few info about how to use it.

 

Hope there is a guide or example for users about how to use mcuboot.

My project needs serial bootloader function.

Hi,

It doesn't seem to be working for me. Here's a test program

#include <zephyr.h>
#include <misc/printk.h>
#include <math.h>

void main(void)
{
printk("round up %d  \n\r",round(5.7));
printk("round down %d \n\r",round(5.2));
}

and output I get is

round up 1075314688
round down 1075052544

I'm working with nrf52840 uC.

This is on BOARD=qemu_cortex_m3 which uses the ARM soft float ABI.  There's a chance that you've got a mix of hard float / soft float code but I thought the linker checked that.

What board is this for?

Hi Michael,

After switching to new library, code compiles but it rounds off all the values to 0.

Hi Ashish.  I haven't used this personally, but try switching the libc from the built-in minimal libc to newlib.  See http://docs.zephyrproject.org/subsystems/c_library.html for more.

A couple of things come to mind here:

Is root_models[0] really the model that's supposed to do the publishing?
It's often the Configuration Server Model, which would explain the error
you're getting. You didn't show the definition of your models array, so
I'm just guessing here.


You are right... Mistakenly specified the cfg_srv model. It is working fine now :)
 
Also, if this is really a formal publish message you're sending, you
should be using the bt_mesh_model_publish() API instead of
bt_mesh_model_send(). The latter is intended mainly for client model
messages as well as for the server's responses to those, and it doesn't
take into consideration things like the Model Publish Retransmit state
or that you're actually publishing using the configured publication
state (correct app key, destination address, TTL, etc).


Sure, will make use of it. Thanks for the clarification!

Unable to set Appkey for generic server model

Mani Sadhasivam
 

Hello,

My objective is to use 96Boards carbons running Zephyr to form a mesh network for publishing sensor data. For testing purposes, I am using Generic ON/OFF server model for sending the sensor data to all nodes in the network, later this will get replaced by Sensor server model.

However, after provisioning the node using `meshctl` and binding AppKey to the model, publishing sensor data from node results in the below error:

[bt] [ERR] model_send: Model not bound to AppKey 0x0001

Thread used for publishing sensor data:

void temp_work_thread(struct k_work *work)
{
        if (node_addr == BT_MESH_ADDR_UNASSIGNED)
                return;

        struct net_buf_simple *msg = NET_BUF_SIMPLE(3 + 4);
        struct bt_mesh_msg_ctx ctx = {
                .net_idx = 0,
                .app_idx = 1,
                .addr = BT_MESH_ADDR_ALL_NODES,
                .send_ttl = BT_MESH_TTL_DEFAULT,
        };

        bt_mesh_model_msg_init(msg, BT_MESH_MODEL_OP);
        net_buf_simple_add_u8(msg, 1);

        if (bt_mesh_model_send(&root_models[0], &ctx, msg, NULL, NULL)) {
                printk("Unable to send sensor message\n");
                return;
        }

        printk("Sensor message sent with OpCode 0x%08x\n", BT_MESH_MODEL_OP);
 
}

Meshctl commands for provisioning and binding AppKey:

discover-unprovisioned on
provision 0108  # Node address 0108
menu config
target 0108
appkey-add 1
bind 0 1 1000 # bind AppKey 1 to model 1000 of 0th element

Above commands seems to succeed with below debug message:
