CC2530: Defining Custom Cluster, Commands and its callbacks

Ajit_Wadekar

Part Number: CC2530

Hello,

I need to define custom cluster, its commands, its attributes and callbacks for commands.

So I understood how to define custom attribute and its commands. Also I got a jist of how I can define a callback.

But I am unable to understand how will that custom callback be called once the required custom command is recived, can anyone help me understand this?

You can call your custom cluster callback in ZCL_INCOMING_MSG event.

Dear Yikai,

But when is this called? Because I was checking for ON/OFF Command, I dint find it calling ZCL_INCOMING_MSG.

It’s a very fundamental cluster command callback so it is invoked in zcl_general.c

Dear Yikai,

Thank you. I will test this and get back to you if there is any problem.

Also can I define a callback to update the attribute?

When you add an attribute to a cluster, even it is custom cluster, zcl would update attribute when you do attribute write.

Dear Yikai,

Is it possible to add custom command in predefined cluster like ON/OFF cluster?

It should be possible.

Dear Yikai,

Thanks for the reply.

So I tested by defining custom command in one of the cluster. And I sent the command from coordinator I get a response Status: Unsupported Cluster Command (0x81).

Also I tried to add a breakpoint in zclApp_ProcessIncomingMsg, the breapoint never hits for this command.

Could you please help me with this.

I remember ON/OFF cluster has its own command callback. I think you need to refer to how zcl implement standard ON/OFF command callback and do it accordingly.
