I'm using sdk 15.3.0 and s132.
Is there an API that I can query the bluetooth connection status?
What method can I use to find out if a connection is currently available or not?
my goal is don't to do disconnect if the connection is not already there. how can i make it?

Hello,

The application is responsible for keeping track of the connection status. The easiest way to do this is probably by keeping a global flag such as 'm_conn_handle' in ble_app_hrs example. Another option is to use the SDK Connection state module. It has the ble_conn_state_status() function to query the connection state for a given connection handle.
