mesh SDK add SIG model

[Ricky]

I added a SIG general onoff model by modifying nordic mesh SDK example project 'example/light_switch', just modified model ID as below:

client:

#define SIMPLE_ON_OFF_CLIENT_MODEL_ID (0x1001)

server:

#define SIMPLE_ON_OFF_SERVER_MODEL_ID (0x1000)

other:

#define ACCESS_COMPANY_ID_NORDIC (0xFFFF)//as ACCESS_COMPANY_ID_NONE for SIG model

Then the provision can not success, why?

Hello Ricky,

If you only modified the model ID and also the company ID, the server will crash when running "simple_on_off_server_init()".

Since in the "simple_on_off_server_init()", the API "access_model_add()" is called. Inside the "access_model_add()", the opcode format will also be checked.

Since you try to use the "generic on/off mode", the opcode length should be two bytes.

The detail can be found in Mesh specification v1.0, 3.7.3.1, page 93

So I would like to suggest you modified the opcode in simple_on_off_common.h like:

SIMPLE_ON_OFF_OPCODE_SET = 0x8202,            /**< Generic OnOff Set. */
SIMPLE_ON_OFF_OPCODE_GET = 0x8201,            /**< Generic OnOff Get. */
SIMPLE_ON_OFF_OPCODE_SET_UNRELIABLE = 0x8203, /**< Generic OnOff Set Unreliable. */
SIMPLE_ON_OFF_OPCODE_STATUS = 0x8204          /**< Generic OnOff Status. */

And the server and client should work correctly.

Best regards,

Rick

Yes, it is this problem. Thank you.

Hi Jui-Chou (Rick) Chung,

I'm working with ble mesh sdk 2.2.0 and I need to add more SIG models other than the three included by nordic.

The problem is that I cannot find, on the bluetooth sig docs, the list of opcodes like the on-off example you listed above.

Can you please help?

[Jui-Chou (Rick) Chung]

Hello Luciom,

There are three specifications related to the Bluetooth mesh, and I would like to suggest you check the "Model specification" which shows in the here.

Hi Jui-Chou (Rick) Chung,

Of course I am working on the basis of the document you mentioned, but I do not find references to opcodes.

Maybe something escapes me.

I asked this question that may seem obvious for this reason.
