BLE connection terminated

Dear all,

According to BLE spec, I understand that main device goes into Scanning immediately after a connection lost. Is it possible to configure a device to wait longer before start scanning again after a connection lost?

Thanks!

    This is not mandated by the spec. You can choose any amount of time to start scanning after a connection drop. You could also never scan again if you really wanted to.

    Dear Tim, thanks a lot for your answer.

    In the other hand, once the connection is established and given a case where the peer device will send only one packet (or few) with large amount of time between every packet transmission (like minutes or more) : Does the master have to wait for a Supervision Time Out to consider connection lost? or could I configure the master to terminate the communication after the packet reception? (like that the master can sleep until next Scanning and save some energy)

    Thanks in advance!

    The master can terminate the connection whenever it desires. The master can do this either gracefully with a connection termination request or can just immediately stop showing up or connection events, thus causing the slave to timeout due to supervision timeout.
