of the central are used for connection setup. If both modules have different connection
interval settings the peripheral requests the central to accept the peripheral's settings af-
ter 5s. The central accepts these settings, and thus the peripheral's connection interval
is used.
If now another Bluetooth
Proteus-III module (peripheral) and the connection interval settings do not coincide, the
Proteus-III requests the smart phone to accept its settings after 5s. If the cell phone
does not accept the settings, it will be requested a further 3 times with a delay of 10s.
If the peripheral's settings request have been rejected in all cases the connection will be
shut down. If the smart phone itself requests to update the connection interval of the
Proteus-III, the module accepts the request. Reversely, if a Proteus-III (central) connects
to another Bluetooth
coincide, the Proteus-III accepts all requests of the peripheral to update the connection
parameter settings.
• The connection supervision timeout defines the time after which an already established
connection is considered as lost, when no further communication has occurred.
Please ensure that all members (Proteus-III, cell phones and other

ters to avoid connection problems and changes of the connection interval dur-
ing an opened connection.
Please check the minimum connection interval that is supported by iOS. Former
iOS devices do not support connection intervals shorter than 30ms!
