Using broadcaster role

Hi, I'm trying to use my device in the broadcaster role, but so far I've been unable to do it. I'm using the ble_app_barebone example to do it.

I'm change the parameters .role and .mode in the config.h file from GAP_ROLE_PERIPHERAL and GAP_LIM_DISCOVERABLE to GAP_ROLE_PERIPHERAL and GAP_BROADCASTER_MODE, respectively.

I've also changed the gap start function, from app_easy_gap_undirected_advertise_start() to app_easy_gap_non_connectable_advertise_start() in the user_barebone.c file.

Even with this changes, when I run the application it stops and goes to NMI_Handler.

我遗漏了什么东西?

Thanks in advance.

Hi TMiranda,

When a device acts as a broadcaster, that means that its able to support only non-connectable advertising. Please follow the steps below in order to configure your device as broadcaster. I made these steps in the ble_app_barebone example of the SDK 5.0.4.

Change to GAP_BROADCASTER_MODE the .mode item of the user_adv_conf structure in the user_config.h header file

Change to GAP_BROADCASTER_ADV the .role item of the user_adv_conf structure in the user_config.h header file.

Add cmd =app_easy_gap_non_connectable_advertise_get_active(); instead of the cmd = app_easy_gap_undirected_advertise_get_active(); in user_app_adv_start() function of the user_barebone.c file

Add the app_easy_gap_non_connectable_advertise_start(); instead of the app_easy_gap_undirected_advertise_start();in user_app_adv_start() function of the user_barebone.c file

Add a user_app_on_adv_nonconn_complete() function as the user_app_adv_undirect_complete(). This function will be triggered when the non-connectable advertising completes. Probably that’s was the reason of the NMI.

添加user_app_on_adv_nonconn_complete in the user_app_callbacks structure of the user_callback_config.h header file as follow :

.app_on_adv_undirect_complete = user_app_adv_undirect_complete,

Thanks, PM_Dialog

Hi, thanks for the fast

Hi, thanks for the fast answer.
I'm doing the above mentioned, but I'm facing the following error:
"error: #20: identifier "user_app_on_adv_nonconn_complete" is undefined
.app_on_adv_nonconn_complete = user_app_on_adv_nonconn_complete,"

I'm adding the user_app_on_adv_nonconn_complete() function on the user_barebone.c file this way:
"void user_app_on_adv_nonconn_complete(uint8_t status)
{
// If advertising was canceled then update advertising data and start advertising again
if (status == GAP_ERR_CANCELED)
{
user_app_adv_start();
}
}"

Which is equal to the app_easy_gap_undicrect_advertise_start().

Then, I'm calling it on the user_callback_config.h like this:

" .app_on_adv_nonconn_complete = user_app_on_adv_nonconn_complete,"

I've also followed all the other steps too. Is there something I'm missing?

Hi TMiranda,

You should make a reference of the user_app_on_adv_nonconn_complete() function into the ble_app_barebone.h header file. Please, how we define all our user application function. So, please add this code snippet into the ble_app_barebone.h:

void user_app_on_adv_nonconn_complete(uint8_t status);

Thanks, PM_Dialog
