Detailed Description

Parameters defining the scan process.

The scan process is defined by two main parameters:

  • The scan window that defines how long the device should scan.
  • The scan window that defines how frequently the device should scan.

To scan continuously, the scan window and the scan interval should have the same value.

To get extra data from the advertising device, the scanner can send scan requests to the advertiser; the advertiser may respond with scan responses. It is possible to select what type of address is used to issue the scan request.

With Bluetooth 5, devices can advertise on more physical channels, and by extension, they can scan on more physical channels. It is possible to define independent scan parameters for every scannable physical channel.
