.. title:: BT_TICKER_COMPATIBILITY_MODE

.. option:: CONFIG_BT_TICKER_COMPATIBILITY_MODE

*Ticker compatibility mode*

Type: ``bool``

Help
====

This option enables legacy ticker scheduling which defers overlapping
ticker node timeouts and thereby prevents ticker interrupts during
radio RX/TX. Enabling this option disables the ticker priority- and
'must expire' features.
