Legacy HAL#

The Legacy HAL is an implementation of the Hardware Abstraction Layer (HAL) that was used by the Zigbee EmberZNet and Flex Connect stacks before their transition to the new component-based architecture (Zigbee version 7.0 and Connect version 3.0).

This component is not a complete duplicate of the old HAL. It only contains the most commonly used pieces to enable our networking stacks and sample applications and to support porting customer applications to the new component-based implementation. Currently, Zigbee and Connect sample applications are dependent on this component. Eventually, they will be ported to use new HAL components directly so that this component can become optional or be deprecated. Note

  • This component is only designed to be used with Zigbee and Connect stack applications. Do not use with any other stacks as it will likely introduce problems.
