:orphan: .. title:: BT_CONN_PARAM_UPDATE_TIMEOUT .. option:: 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."
