CONFIG_BT_CONN_PARAM_UPDATE_TIMEOUT
¶
Peripheral connection parameter update timeout in milliseconds
Type: int
Help¶
The value is a timeout used by peripheral device to wait until it
starts the first connection parameters update procedure after a
connection has been established.
The connection parameters requested will be the parameters set by the
application, or the peripheral preferred connection parameters if
configured.
The default value is set to 5 seconds, to comply with the Bluetooth
Core specification: Core 4.2 Vol 3, Part C, 9.3.12.2:
"The Peripheral device should not perform a Connection Parameter
Update procedure within 5 seconds after establishing a connection."
Direct dependencies¶
