MESH BLE with custom HW proof of concept

JoseSecmotic

Hi everyone,

I'm trying to evaluate the BLE mesh SDK, using the example of the light_switch.

I have the SDK15 and the the SDK_mesh v2 and I am able to compile everything just fine. The provisioner also registers the client as expected.

The problem that I am facing is that both provisioner and client are DK boards, but the servers I have are also nrf52832, but custom hardware.

I'm trying to do a proof of concept in which the client, after pressing one button, turns on the client's LED (in the address 29 in my case).

What I have done is modifying the BSP_BUTTON_LED in the pca10400.h for the address of my interest, but this had no success.

Could you give me some guidance on how to achieve this? I think I am pretty close but I am getting lost

Another question that I am facing, is that the devices are mobile, so.. when should the provisioner provision the different servers or clients? I think that it will not be very useful if everytime that I get a disconnection on a device it has to be provisioned again.

Thanks in advance and best regards

    Sorry, when I said:
    "I'm trying to do a proof of concept in which the client, after pressing one button, turns on the client's LED (in the address 29 in my case)."
    I meant that, after pressing one button, turns on the SERVER's LED, which is the custom hardware

    If you turn on persistent storage on all of the nodes, the nodes will still remain a part of the mesh network if the connection is lost or a power loss occurs. See this video for a good intro.

    What custom HW are you currently using? Is it a module? Also, which mesh sdk are you using? v2.0.1, v2.1.1?

    It should work to just use the led functionality like it is done in the button_event_handler() function in the light switch server for example. The hal_led_pin_set() function is called, which changes the value of the NRF_GPIO register. The LED_PIN_NUMBER DEFINE is set to BSP_LED_0, which is again defined as LED_1. LED_1 is defined as pin 17 (see pin assignment doc for more info). Also, these two cases could be useful: case 1, case 2.
