When using the LTE link controller library, a memory comparison is done between padded structs that may result in comparing bytes that have undefined initialization values. Other issues CIA-857: LTE Link Controller spurious events Serial LTE Modem NCSDK-13895: Build failure for target Thingy:91 with secure_bootloader overlayīuilding the application for Thingy:91 fails if secure_bootloader overlay is included. Reduce the value of CONFIG_NRF_MODEM_LIB_SHMEM_TRACE_SIZE to 8 Kb, however, this might lead to loss of modem traces.įor memfault, use Secure Partition Manager instead of TF-M by setting CONFIG_SPM to y and CONFIG_BUILD_WITH_TFM to n. Use Secure Partition Manager instead of TF-M by setting CONFIG_SPM to y and CONFIG_BUILD_WITH_TFM to n. Workaround: Use one of the following workarounds for modem traces: The nRF9160: Asset Tracker v2 application configured for LwM2M cannot be built for the nrf9160dk_nrf9160_ns build target with CONFIG_NRF_MODEM_LIB_TRACE for modem traces or nf for memfault due to memory constraints. CIA-661: Asset Tracker v2 application configured for LwM2M cannot be built for the nrf9160dk_nrf9160_ns build target with modem traces or memfault enabled CIA-604: ATv2 cannot be built for the thingy91_nrf9160_ns build target with SECURE_BOOT enabledĭue to the use of static partitions with the Thingy:91, there is insufficient room in the flash memory to enable both the primary and secondary bootloaders. NCSDK-14235: Timestamps that are sent in cloud messages drift over timeĭue to a bug in the Date-Time library, timestamps that are sent to cloud drift because they are calculated incorrectly. The network mode string contains the network modes that the modem is configured to use, not what the modem actually connects to the LTE network with. The network mode string present in deviceInfo (nRF Cloud) and dev (Azure IoT Hub and AWS IoT) JSON objects that is reported to cloud might contain wrong network modes. CIA-463: Wrong network mode parameter reported to cloud Workaround: The implementation for supporting the nRF Cloud FOTA_v2 can be found in the following commits:Īsset Tracker v2 CIA-845: The application cannot be built with overlay-carrier.lib (carrier library) enabled for Nordic Thingy:91īuilding with LwM2M carrier library enabled for Nordic Thingy:91 will result in a FLASH overflow and a build error. The nRF9160: Asset Tracker application does not support the nRF Cloud FOTA_v2 protocol. IRIS-2676: Missing support for FOTA on nRF Cloud This causes the application to crash if the user toggles one of the switches before the kit is connected to the cloud. The nRF9160: Asset Tracker application does not wait for connection to nRF Cloud before trying to send data. Sending data before connecting to nRF Cloud The nRF9160: Asset Tracker might show up to 2.5 mA current consumption in idle mode with CONFIG_POWER_OPTIMIZATION_ENABLE set to y. NCSDK-6689: High current consumption in Asset Tracker The nRF9160: Asset Tracker application prints warnings and error messages during successful FOTA. Workaround: If you are using nRF9160 DK v0.15.0 or higher and Thingy:91 v1.4.0 or higher, set CONFIG_NRF9160_GPS_ANTENNA_EXTERNAL to y.Īlternatively, for nRF9160 DK v0.15.0, you can set the CONFIG_NRF9160_GPS_COEX0_STRING option to AT%XCOEX0 when building the preprogrammed Asset Tracker to achieve the best external antenna performance. The preprogrammed Asset Tracker does not come with the best external antenna performance. Workaround: Set CONFIG_FW_INFO in MCUboot. See the related NCSDK-6898 known issue in Build system for more details. The immutable bootloader is not able to find the required metadata in the MCUboot image.
