nrf52840 ble mesh: Toggle function for generic ONOFF SERVER

[stefanogradozzi]

Hello,

Is there the possibility for a node with a Generic OnOff Client (BUTTON) to send a unique toggle command to a Generic OnOff Server (LED), instead to use 'bt_mesh_onoff_cli_set_unack' function and build a toggle logic changing the set value every time I push the button?

It could be an important feature in a system where there are for example two clients (BUTTON1 and BUTTON2) that command a single server (LED0).

When I press a button (it does not matter which) I want that LED0 goes ON, the when I press a button again (it does not matter which) I want that LED0 goes OFF and so on.

But if I use 'bt_mesh_onoff_cli_set_unack' function for BUTTON1 and BUTTON2 here is what happens:

Press BUTTON1 --> LED0 ON

Press BUTTON2 --> LED0 ON!! (I wanted LED0 OFF)

Press BUTTON1 --> LED0 OFF

Press BUTTON2--> LED0 OFF!! (I wanted LED0 ON)

and so on

Best regards

Hello,

There is no toggle functionality in the Mesh Model specification, so this functionality needs to be implemented in the application.

But if I use 'bt_mesh_onoff_cli_set_unack' function for BUTTON1 and BUTTON2 here is what happens:

Press BUTTON1 --> LED0 ON

Press BUTTON2 --> LED0 ON!! (I wanted LED0 OFF)

Press BUTTON1 --> LED0 OFF

Press BUTTON2--> LED0 OFF!! (I wanted LED0 ON)

It looks like the application is not aware of the LED0 state. On each button press; get the LED0 OnOff state and use the inverted value to set it. There should also be more ways to solve this.

Best regards,

Maria
