RF_ScanFactor
10
This parameter defines the factor between the scan window and the scan interval. See RF_
ScanTiming for more information.
Example: Let's assume that the scan window is 50ms, the RF_ScanFactor is 3, then the mod-
ule scans for 50ms on a fixed channel, enters a suspend mode (system-on mode) for 100ms
(3×50ms - 50ms), switches the channel, again scans for 50ms and so on. The larger the
RF_ScanFactor , the less time the module scans and thus the less power is consumed, but also
the more difficult it is to detect other Bluetooth

Set the scan factor to 0x03 using CMD_SET_REQ with settings index 10.

8.14.2. Example 2
