3.2.1.17 ST,<interval>,<latency>,<timeout>
This command sets the initial connection parameters for future connections. The
three input parameters are all 16-bit value in hex format. To modify current
connection parameters, please refer to action command “T”.
For central device, the connection parameters will be used to establish connections
with peripherals. For peripheral device, the connection parameters will be used to
request the connection update once a new connection is established. Acceptance of
connection update from a peripheral device depends on central device.
The corresponding get command “GT” returns the desirable connection parameters
set by command “ST” when connection is not established. Once connection is
established, the actual connection parameters will be displayed in response to
command “GT”.
Connection interval, latency and timeout are often associated with how frequent
that a peripheral device needs to communicate with central, therefore, closely
related to power consumption. The three parameters’ range and relationship are
listed in table 6
