Help¶

Enable the quirk wherein BT Host stack will auto-initiate Data Length Update procedure for new connections for controllers that do not auto-initiate the procedure if the default data length parameters are not equal to the initial parameters.

This has to be enabled when the BLE controller connected is Zephyr open source controller.
