When scanning for Bluetooth® devices there are many options to consider. Should the device actively or passively scan? What technology should be used? These options affect the power usage, what tags are found and what data is retrieved from said tags. The device can be configured using the following parameter tab:
- Use Active Scanning - If this is set to "Yes", then the device will actively scan, responding to every tag it finds, asking for more data. For more information click here.
- Scan technology - Sets the technology to use during the scan. Either long range or standard. For more information click here.
- Scan technology period - If both scan technologies are required then this is the number of seconds between scan technology changes. This is required as both technologies cannot be used concurrently. If both technologies are required, typically the total scan length should be twice the normal length, and the scan technology period should be half the scan length.
