I find out that
The s110 can only connect to a single central, but is able to do non-connectable advertising while in that connection
by here
So is this scenario possible? One s110 device ‘A’ connect to central ‘B’, at the same time device 'A' send non-connectable advertising, Then central device 'C' do scan, device ‘A’ can get the event 'BLE_GAP_EVT_SCAN_REQ_REPORT', then 'A' disconnect to 'B' and wait for another connection.
if it is possible, how to configure if use event 'BLE_GAP_EVT_SCAN_REQ_REPORT'?
Thanks!
