Check the host's connection status on the peripheral device

When I tracked it down, I realized that the error was occurring in on_adv_evt in advertising_init, so I commented it out and it worked fine.
Thanks!

If you are in a connection, peripheral and central connected. And the peripheral starts connectable-advertising again, and an additional central connects, you will get a BLE_GAP_EVT_CONNECTED event in the ble_evt_handler.

Okay, let's change the question.
With the peripheral device and host connected, use connection request comes from another host, where do you detect it?
I don't think it's detected in the ble_evt_handler.

Hi,

You get the BLE_GAP_EVT_CONNECTED event, with address, etc, when a device connects, and likewise a BLE_GAP_EVT_DISCONNECTED when a device disconnects. The application needs to keep track of this.

The ble_conn_state library could help keep track of this. https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_ble_conn_state.html

The reason for combining the three is that when you connect a 'b' peripheral while 'a' peripheral is connected, i disconnect 'a' peripheral and connect only 'b' peripheral .

I would like to know how I can check if device 'A' is currently connected to device 'B' on a peripheral.

Hi,

You can use sd_ble_gap_disconnect() to disconnect a link.

If you only want 1 device to be connected, then maybe you don't need to functionality provided by "multiperipheral"
