I have a vendor mesh model that needs to send a custom 8 byte message.
Here are some definitions
BT_MESH_MODEL_PUB_DEFINE(vnd_pub, NULL, 3 + 8); <--what is with this plus notation that I see in all samples? Does this mean 3 for vendor opcode and 8 for data? The documentation for the macro just says that the third parameter is the size
The message is defined as follows
typedef struct __attribute((packed))
{
uint16_t data1: 14;
uint16_t data2: 14;
uint16_t data3: 14;
uint16_t data4: 7;
uint16_t data5: 7;
uint16_t data6: 7;
uint16_t unused : 1;
} my_mesg_msg;
The message is sent the following way:
my_mesg_msg msg = {
..initialize the message values
};
bt_mesh_model_msg_init(vnd_models[0].pub->msg,BT_MESH_MODEL_OP_3(0x0E 0x59));
net_buf_simple_add_mem(vnd_models[0].pub->msg,(void*)&msg,sizeof(msg));
bt_mesh_model_publish(&vnd_models[0]); (returns 0)
Here is the log output from the mesh stack

Any idea why?
Thanks
