Description
Sets the minimum interval in which the Peripheral and Central device will go into the
transmission mode to communicate data after the Peripheral device is connected. A
lower minimum interval means faster data rate but more power consumption.
Specifies the maximum connection interval that the Peripheral device supports. Central
and Peripheral devices must agree upon the connection interval to have a successful
connection. The actual connection interval is negotiated with the Central device during
connection.
Sets the maximum number of times the Peripheral device can choose not to answer
when the Central device requests data. It is useful for devices that want to send data at
a faster rate but also want to remain in the low-power mode when no data is present to
be sent.
For this project, no slave latency is required.
Sets the total time after the last successful connection event for which the Peripheral or
Central device will consider the connection alive. If no connection event happens during
this time, then the link is assumed broken, so devices disconnect.
6. Click Security under Peripheral role to configure the security level of the BLE communication. This project does not
require security settings, so set the I/O capabilities to No Input No Output and Bonding requirement to No Bonding.
Keep the rest of the settings at their default values and click Apply, as shown in Figure 22.
