mfw-nr+_nrf91x1 release notes ----------------------------- ** Introduction to the mfw-nr+_nrf91x1 release notes ** These release notes describe the changes in the mfw-nr+_nrf91x1 firmware from version to version. The release notes are intended to briefly list all relevant changes in each version. Copyright (c) Nordic Semiconductor ASA. All rights reserved. *** mfw-nr+-phy_nrf91x1_2.0.0 ********************************** The mfw-nr+_nrf91x1 is the DECT NR+ firmware for modem subsystem of nRF9131 LACA A0, nRF9151 LACA A0, nRF9151 LACA A1 and nRF9161 LACA A0 SiP modules. It supports Release 2 of the DECT-2020 New Radio (NR) technical specifications version 2.1.1. DECT NR+ operation is enabled on frequency bands 1, 2, 4, 9, and 22. DECT NR+ band 4 is supported by the nRF9151-LACA-A0 and nRF9151-LACA-A1. It is advisable to use the latest versions of the nRF Connect and nRF Connect Programmer tools. This release aligns with v1.3 of the nRF91x1 DECT NR+ AT Commands Reference Guide. *** New functionality ********************* - L1 control and scheduling: - Refactored for improved maintainability - Clock Synchronization: - Support for modem clock synchronization to external 1PPS reference - Support for 1PPS reference clock generation - Bug Fixes: - Rejection of duplicate operation handles - Fix reset of coexconfig on nrf_modem_dect_phy_init - Removed unnecessary AT commands *** Known Issues **************** - If modem sees very high (>-30dBm) input signal during modem activation DC-offset calibration may fail, leading to incorrect RSSI results and failed transmissions with LBT. Workaround is to cycle modem activation. - Transmission with LBT fails if LBT period duration is set to 5760-5817 clock ticks. Workaround is to avoid these LBT durations. - Modem internal tracing for customers, when enabled with Nordic provided trace database, has physical bandwidth limitation which may cause for larger packets peak throughput degradation. - Customer tracing can be enabled on-request basis for joint Nordic-Customer deep modem debugging purposes. *** MD5 checksums ***************** 21746FD.ipc_dfu.signed_2.1.0.ihex 974651373acf63ac802618a7e327b662 (MD5) firmware.update.image.digest.txt 184b6deb74e451488b52f78e6d3ede78 (MD5) firmware.update.image.segments.0.hex bcb2a97e426006215104ee39b2cde466 (MD5) firmware.update.image.segments.1.hex c9e8b81ee1a9c4d715cfe2d9a23e6e3a (MD5) ipc-dfu_nrf91x1_2.1.0.ihex 974651373acf63ac802618a7e327b662 (MD5) mfw-nr+-phy_nrf91x1-license-agreement.txt d1fdbb8f743cb2464a3f671060e77c82 (MD5) mfw-nr+-phy_nrf91x1_2.0.0.cbor 48d70b40d0c81982c190154022357867 (MD5) mfw-nr+-phy_nrf91x1_2.0.0_trace-db.json 51636f6bdb3b56db5a8bd75f740768cc (MD5) ********************************** The mfw-nr+_nrf91x1 is the DECT NR+ firmware for modem subsystem of nRF9131 LACA A0, nRF9151 LACA A0, nRF9151 LACA A1 and nRF9161 LACA A0 SiP modules.
