is it possible to recognize device side , if ble disconnected host has gone to sleep or it has got device bonding infos deleted?

[astella]

To the kind attention of Nordic support team,

In case of a device and host ble bonded, I'm giving a look at disconnection reasons codes due to (1) host entering sleeping mode, and

(2) removing bonding infos only host side. Disconnection reason seems to be the same in both case (BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION) decoding

p_ble_evt->evt.gap_evt.params.disconnected.reason

according to

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s140.api.v6.1.1%2Fgroup___b_l_e___h_c_i___s_t_a_t_u_s___c_o_d_e_s.html&resultof=%22BLE%5FHCI%5FSTATUS%5FCODE%22%20

Can you please confirm?

So there is no way to distinguish device side those two scenarios?

Thank you for your kind suggestions

Best regards

The Status Codes are defined by the Bluetooth SIG - you could check to see if there are any which give the information you require.

Of course, it depends on the Host as to what codes are actually sent ...
