Enable/Disable Bluetooth.

[S_Ma]

Hi,

I use nRF5 SDK v15.0.0. In my application I need periodically disable and enable Bluetooth because they are wifi also, which connected to the same antenna. Its mean the receiver of the Bluetooth also mast be disabled. For that I completely disable and enable the SoftDevice, but it takes a long time.

Otherwise how I can disable Bluetooth? If I only stopped advertising, then Bluetooth receiver disabled or not?

Thanks.

Hi.

You can SoftDevice API's that you can use without disabling the SoftDevice here. Here is also a message sequence chart for peripheral connection establishment and termination.

You can start/stop advertising using sd_ble_gap_adv_start() and sd_ble_gap_adv_stop(). If you are in a connection you can use sd_ble_gap_disconnect() to disconnect from the central. In the ble_app_uart example, use the bsp_event_handler() in main.c to implement the functionality you want on different button events.

Thank you for the answer.
I used sd_ble_gap_adv_stop() and sd_ble_gap_disconnect() functions, but i don't sure that Bluetooth receiver disabled. For that I disable SoftDevice after stopped advertising and disconnected from the central.

Can I use only sd_ble_gap_adv_stop() and sd_ble_gap_disconnect() functions for completely disable Bluetooth? Can I sure that receiver disabled after stopped advertising?

Hi.

As you say, disabling the SoftDevice takes time, but the radio is only active when you are advertising or in a connection, so by using sd_ble_gap_adv_stop() and sd_ble_gap_disconnect() the Bluetooth should be completely disabled.
