Changelog¶
All notable changes to this project are documented in this file.
nRF Connect SDK v1.4.0¶
Changes¶
Changed the timeslot implementation to support up to 8 concurrent sessions (DRGN-13952). It is now necessary to supply a timeslot context configuration using
mpsl_timeslot_session_count_set()
. All timeslot APIs now take asession_id
as input. The session id is retrieved frommpsl_timeslot_session_open()
.Added an API to use Front-End Modules, like the nRF21540 GPIO or a simple GPIO, with the protocols and an API to configure them using the application. Only the nRF52 series is supported.
Bugfixes¶
Fixed an issue where the high frequency clock and
TIMER0
were not turned off during idle periods shorter than 9 ms (DRGN-14152). This increased the average power consumption. Such a case could occur when running a Bluetooth LE connection with a connection interval of 7.5 ms.
Known Issues and limitations¶
See the Known issues page in nRF Connect SDK for the list of known issues and limitations for this release.
nRF Connect SDK v1.3.0¶
Added¶
Added API for fetching build revision information.
Added API to set a TX Power envelope. Protocols using MPSL will limit their TX power to a value equal to, or lower than, the provided value.
Added support for using a low-swing and full-swing LF clock.
The support for integrating an 802.15.4 driver is now improved.
nRF Connect SDK v1.2.0¶
Added¶
Added a library version with preliminary support for the nRF5340 device. The feature set is the same as in the MPSL library for nRF52. The following library has been added:
soft-float/libmpsl.a
Changes¶
Removed
_nrf52
from the MPSL library file names.Version numbers have been removed from the libraries.
It is no longer allowed to call
mpsl_init()
if MPSL is already initialized.Clock configuration parameters for any stack that uses MPSL must be provided in
mpsl_clock_lfclk_cfg_t
tompsl_init()
. This now also involves clock accuracy.Clock accuracy must be specified in parts per million (ppm).
Renamed MPSL clock API for high and low frequency clock.
MPSL 0.5.0-1.prealpha¶
Initial release.
