It is intended for developers working with the MM6108-EKH05 and MM8108-EKH05 evaluation kits. Each release section documents new features, improvements, known issues, and deprecation notices introduced since the previous release. ## 2 Software Change History ### 2.1 Release 1.9.0 #### 2.1.1 New Features * CMSIS-Pack has been updated to use MM-IoT-SDK release 2.11.2. Please refer to the Release Notes for MM-IoT-SDK 2.11.2 for more information on the changes introduced in this release. * The CMSIS-Pack also includes new components to allow building morselib and hostap from source. #### 2.1.2 Other Improvements * Nil #### 2.1.3 Known Issues * Using IPv6 with the iPerf example fails with traffic not being received.\ Workaround: Manually set the iPerf bind address to ::0 when using IPv6. #### 2.1.4 Deprecation Notices * The FreeRTOS+TCP networking stack has been removed. ### 2.2 Release 1.8.4 #### 2.2.1 New Features * CMSIS-Pack has been updated to use MM-IoT-SDK release 2.10.4. Please refer to the Release Notes for MM-IoT-SDK 2.10.4 for more information on the changes introduced in this release. * The EKH05-Demo example now has a Command Line Interface (CLI) over UART. This provides an interactive interface for controlling the application. #### 2.2.2 Other Improvements * CMSIS-Pack has been updated to make changing between Morse Micro chips (MM6108 and MM8108) and between demo example applications more straightforward. #### 2.2.3 Known Issues * Using IPv6 with the iPerf example fails with traffic not being received.\ Workaround: Manually set the iPerf bind address to ::0 when using IPv6. #### 2.2.4 Deprecation Notices * The FreeRTOS+TCP networking stack is deprecated by MM-IoT-SDK. It will be removed in the next release. ### 2.3 Release 1.7.4 #### 2.3.1 New Features * CMSIS-Pack has been updated to use MM-IoT-SDK release 2.9.7. Please refer to the 2.9.7 release notes for more information on the changes introduced in this release. * Support added for the new MM8108-EKH05 evaluation kit. The out-of-the-box example will flash the LEDs based on the EKH05's accelerometer. * A new CLI example has been added. This allows the user to send commands to the device over the UART, providing an interactive method for status and control of the EKH05. #### 2.3.2 Other Improvements * It is now possible to select the region via BLE when using the out-of-box demo (MM6108-EKH05 only). #### 2.3.3 Known Issues * Using IPv6 with the iPerf example fails with traffic not being received.\ Workaround: Manually set the iPerf bind address to ::0 when using IPv6. ### 2.4 Release 1.6.1 #### 2.4.1 New Features * CMSIS-Pack has been updated to use MM-IoT-SDK release 2.8.2, which includes the 1.15.3 drivers/firmware. Please refer to the release notes for 2.8.2 for more information on the changes introduced in this release. * Support added for the new MM8108 chip. * Support for the persistent config store used in MHS for storing configuration. * A shim template to assist users in getting started with new hardware. See the CMSIS-Pack user guide, chapter 10, for more information. #### 2.4.2 Bug Fixes * WNM sleep failed with a duration of 10 minutes or greater. * In the ping example, the post ping idle time was set to 60ms instead of 60s. #### 2.4.3 Known Issues * Using IPv6 with the iPerf example fails with traffic not being received.\ Workaround: Manually set the iPerf bind address to ::0 when using IPv6. ### 2.5 Release 1.5.0 #### 2.5.1 New Features * CMSIS-Pack has been updated to use MM-IoT-SDK release 2.6.4. Please refer to the release notes for 2.6.4 for more information on the changes introduced in this release. * A new version of HaLow\_example has been added that uses the SDIO interface, allowing users to easily switch between SPI and SDIO. #### 2.5.2 Known Issues * iPerf sessions running over IPv6 do not connect. * WNM sleep fails when the duration is 10 minutes or greater. * The post ping idle time is set to 60 ms instead of 60 s. This will impact power measurements. * Workaround: edit the config file in Core/Src/configs.c and change the following line: {“ping.post\_ping\_delay\_ms”, “60”}, to: {“ping.post\_ping\_delay\_ms”, “60000”}, ## 3 Revision History | Release Number | Release Date | Release Notes | | -------------- | ------------ | ------------------------ | | Version 3 | 26 May 2026 | Update for 1.9.0 release | | Version 2 | 2 Apr 2026 | Update for 1.8.4 release | | Version 1 | 1 Oct 2025 | Initial release | Morse Micro provides this information "as is" without warranties of any kind, express or implied.
