The
enables the possibility to configure the timing behavior of the mod-
ule’s RF interface during an established connection. Using this parameter several predefined
configurations can be chosen, which include the minimum and maximum connection interval,
as well as the connection supervision timeout.
The choice of the
primarily determines how rapidly the connection is
established and data is transmitted. The lower the
, the more frequently
the connected devices communicate with each other and thus, the more power is consumed.

Please note that the smallest minimum connection interval supported by An-
droid is 11.25 ms. Thus profile 0 cannot be used on Android devices. Further
note that iOS supports only profiles, where its minimum connection interval is
15 ms or a multiple of it.
Further information:
• The minimum and maximum connection interval parameters specify the borders of the
connection interval as determined in the negotiation procedure between the central and
the peripheral during connection setup. The connection interval defines the frequency of
communication during connection setup and data transmission. If a Proteus-III module A
(central) connects to a Proteus-III module B (peripheral), the connection interval settings
