Multiprotocol Service Layer

The Multiprotocol Service Layer (MPSL) is a set of libraries that provide common services for single and multiprotocol implementations.

The libraries are available as soft-float, softfp-float, and hard-float builds for the nRF52, nRF54H and nRF54L Series and as a soft-float build for the nRF53 Series.

These libraries provide the following key features:

  • Timeslot. It allows the application to schedule its own events concurrently with other protocols.

  • TX Power control. It provides an API for setting the maximum TX power per channel.

  • Clock control. It provides an API for configuring and controlling the low and high-frequency clock.

  • FEM. It provides an API for controlling external Front-End Modules.

  • SoC Temperature. It provides an API for obtaining the temperature measured on the SoC.

  • IEEE 802.15.4 External Radio Coexistence. It provides an API to control coexistence with IEEE 802.15.4.

  • Bluetooth External Radio Coexistence. It provides an API to control coexistence with Bluetooth.

To enable MPSL in nRF Connect SDK applications, use the CONFIG_MPSL Kconfig option.
