Hi John,

Referring to the doxy documentation here about disconnect(),

https://os.mbed.com/docs/mbed-os/v5.13/mbed-os-api-doxy/class_gap.html#af6f3bf5b22b33d9f3c8dd198618c6b00

It says "Deprecated since addition of extended advertising support. Use disconnect(connection_handle_t, local_disconnection_reason_t) instead", so you need to call it with different parameters. You may need to add below code snippets.

void onConnectionComplete(const ble::ConnectionCompleteEvent &event) {
        _connection_handle = event.getConnectionHandle();
    }

ble_error_t error = _ble.gap().disconnect( _connection_handle, 
        ble::local_disconnection_reason_t::USER_TERMINATION );

ble::connection_handle_t _connection_handle;

Let me know if you need further help.

Thanks, Desmond
