Decommissioning the EnOcean switch

[Terutaka Takeuji]

Hello, I'm an engineer living in Japan.

【Development environment】
"SDK:nRF Connect SDK v2.4.2"
"IDE:VSCode 1.83.1"
"PCA10040(nRF52832)" x 1 (central)
"PTM215B" EnOcean × 1 (peripheral)
"PTM535BZ" + "ECO260" × 1 (peripheral)

This is a question about decommissioning EnOcean switches.

I am proceeding with development based on the enocean sample program stored in SKD.
I sent a commissioning signal from the EnOcean switch to commission the central "PCA10040 (nRF52832)"
and confirmed that it operates normally.

I have confirmed that the main function of "main.c" defines a function that calls back to EnOcean events,
and that the "enocean_commissioned" function is called during commissioning.
However, I did not understand the conditions that would cause the decommission event to occur.
I don't know if there is a way to make the EnOcean switch send a decommission signal.

■main.c (in the main function)
static const struct bt_enocean_callbacks enocean_callbacks = {
.button = enocean_button,
.sensor = enocean_sensor,
.commissioned = enocean_commissioned,
.decommissioned = enocean_decommissioned,
.loaded = enocean_loaded,
};

I have confirmed that there is a "bt_enocean_decommission" function in the EnOcean.c file, but I did not know how to use it.

Question 1)
Please tell me how to decommission EnOcean switches one by one.
It is also possible to send a decommission signal from the EnOcean switch.

Question 2)
Please let me know if there is a way to delete commissioned EnOcean switches all at once.

Thank you for your support.

Hi,

The Bluetooth EnOcean library is only capable of observing the output of the EnOcean devices, and does not send anything back. The decommissioning is only for a device to remove the details of a (separate) switch. For instance, if you have a Bluetooth mesh bridge for bridging EnOcean switch messages into a Bluetooth mesh network, decommissioning can be used to make that bridge not bridging messages from that EnOcean switch into the mesh network anymore.

If you want to decommission all switches, you can use bt_enocean_foreach(), which calls a callback for all commissioned EnOcean devices. Decommission the device in the callback, and decommissioning will be done for all commissioned devices.

Thank you for your reply tesc.

The answer was to use "bt_enocean_foreach()" if you want to decommission all EnOcean switches, so I'll try that.

While checking the answers, I understood that there is no way to decommission EnOcean switches individually, but is my understanding correct?

Also, am I correct in understanding that there is no way to send a decommission signal from the EnOcean switch?

Please give me an answer.

It is possible to decommission EnOcean switches individually through the use of bt_enocean_decommission() if you have the bt_enocean_device structure for the EnOcean switch.

Sorry for the late reply.
I have an additional question for Mr. Taesuk.

I would like to use the bt_enocean_foreach function to erase everything, but I don't know what to specify as an argument.

"bt_enocean_foreach syntax"
bt_enocean_foreach(bt_enocean_foreach_cb_t cb, void *user_data)

question)
bt_enocean_foreach has two arguments, but what should I specify for each?
Please tell me the program code in detail.

I mistakenly continued on with another ticket, so I will only write the conclusion in this ticket.

First of all, the "bt_enocean_foreach()" function is not a function for removing a commissioned EnOcean switch.
This function executes the callback function associated with "bt_enocean_foreach()" for the number of commissioned devices (valid devices only).

Therefore, the function that removes the EnOcean switch is the "bt_enocean_decommission()" function.

I built it based on the "EnOcean" sample, and was able to decommission all commissioned EnOcean switches simply by editing "main.c".

■Delete all EnOcean switches (described in main.c)
static void find_and_decommission(struct bt_enocean_device *dev, void *user_data)
{
　　bt_enocean_decommission(dev);
}
bt_enocean_foreach(find_and_decommission, NULL);

You can remove all EnOcean switches with the above code.
"bt_enocean_foreach()" can be called anywhere in main.c where you want to perform processing.

I had a problem with the button interrupt processing description and was repeatedly failing, but the problem was resolved by writing the button interrupt processing as below.

■Button interrupt processing code
static void button_changed(uint32_t button_state, uint32_t has_changed)
{
　　Processing content…
}
err = dk_buttons_init(button_changed);

thank you very much.
