.. _mpsl_assert: Multiprotocol Service Layer assert ################################## .. contents:: :local: :depth: 2 The Multiprotocol Service Layer assert library makes it possible to add a custom assert handler to the :ref:`nrfxlib:mpsl` library. You can then use this assert handler to print custom error messages or log assert information. :kconfig:option:`CONFIG_MPSL_ASSERT_HANDLER` enables the custom assert handler. If enabled, the application must provide the definition of :c:func:`mpsl_assert_handle`. The :c:func:`mpsl_assert_handle` function is invoked whenever the MPSL code encounters an unrecoverable error.
