The
enables the possibility to configure the timing behavior of the module’s
RF interface during advertising and scanning state. Using this parameter several predefined
configurations can be chosen, which include timing parameters, such as the frequency of ad-
vertising packets and the length of a scan window.
The choice of the
primarily affects the latency of device detection on air as well
as the current consumption. The lower the
, the faster the modules can find
each other for communication, but also the more power will be consumed.

Further information:
• In
ACTION_SCANNING
mode, the scan interval defines the time after which the module
switches channel to detect other Bluetooth
®
LE devices in range. See also
• In
ACTION_SCANNING
mode, the scan window defines the section of the scan interval,
where the module is scanning. During the remaining time, the module enters a suspend
mode (system-on mode). See also
• In
ACTION_IDLE
mode, the advertising interval defines the time after which the module
periodically sends its advertising packet. In between, the module enters a suspend mode
(system-on mode).
• The connection setup timeout defines the time after which a connection request has to
be answered by the peripheral.
Please ensure that all members of a network support the same advertising and
scan timing parameters.
