Occasionally some SVs were not properly used for navigation. - Correction for AGPS / GNSS flash file storage handling, improving robustness of the periodic fix after AGPS is used for a start. - Correction for clock calibration control which may have delayed deep sleep entry in combined NB-IoT and GNSS tracking mode and may slightly increased power consumption. - Improved power consumption when GNSS is active during LTE mode and GNSS is configured with power save mode (duty cycling). - Improved reception performance in a cell with strong interfering neighbor cells in very weak own cell signal condition. - Correction for 3GPP defined protocol stack test loop re-initialization procedures. - Correction for USAT event sending in case of USIM application toolkit is busy. - Correction for handling UICC failure responses and incorrect detection of SIM card connection loss. - Correction for USIM application reinitialization procedure in case if UICC activation failed at first time. - Robustness improvement to DTLS handshaking by adjusting TLS guard timer. - Correction for error reporting code towards application domain when sending UDP packets that are too large for modem to handle. - Correction and improvement of handling large EFmsisdn during UICC initialization. - Correction for attach instability at possibly overlapping SIM refresh and RRC Connection Establishment operations. - Correction for possible minor and momentary NB-IoT reception performance loss due to AFC computation error. - Correction for minor performance loss in NB-IoT own cell RSRP measurement accuracy. - Correction for NB-IoT AGC performance.

Upon collision in Paging Time Window and non-MTC cell detection there was small possibility (timing) where DUT reset. - Corrected calculation of Pathloss for selection of CE level for Preamble transmission when Cell bandwidth is 1.4MHz. - Correction for a use case where manual PLMN selection was not immediately initiated due to an ongoing EMM procedure. - Correction for scenario where Extended Access Barring (EAB) alleviation was not detected correctly. Due to this rare failure UE was not always able to wake up from PSM correctly. - Correction for length encoding of "SMS TPDU" TLV object in the SMS-PP data download envelope that is sent by USAT module to SIM card. - Correction to ensure that UICC polling timer is restarted correctly after presence detection is stopped. - Correction for PTW re-setting to manufacturer default values when using AT%XPTW command. Earlier zero values were set instead of defaults. - Correction for the use case where UE tried to erroneously send user data for a moment after USIM card was removed. - NB-IoT stability and performance improvements when invalid downlink subframe configurations are configured from network. - Correction for a scenario where UE could halt during switch-off (AT+CFUN=4) triggered with recently started Attach procedure. - Correction for EMM functionality so that T3440 is stopped at the receive of ESM DATA TRANSPORT. This enables UE to send uplink PDUs again and there will be less buffered UL data. - Instability correction in cell selection or in cell reselection when operating in coverage enhanced mode and receiving multiple system Information broadcast messages. - Wrong RSRQ format (Q format) was used in trace LOG_OBJECT_NEIGHBOR_CELL_MEASUREMENTS instead of integer dB format. - Correction for the use case where re-Attach triggered by protocol failed in case APN was configured for the initial PDN connection. - Changed and improved completing of Control Plane Service Request procedures. Change improves scenarios where REL14 level network sent security protected PDUs to UE. - Correction for a scenario where service request attempt counter was not reset after T3325 expiry. Due to this incorrect behavior T3325 was started again already after only one failed service request attempts. - Correction for a scenario where USIM card was removed while UE was in PSM. UE failed to camp on cell and signal Detach Request in this case. - Correction for modem instability in case if eligible system information is not scheduled in current cell. - Correction for halt caused by crossover scenario of LTE registration and de-registration. Attach abnormal case F. *** Limitations *************** - TLS/DTLS - Up to three simultaneous TLS/DTLS connections are possible. - Server certificate expiry time is not verified. - pkcs#8 is not supported. - Absolute maximum number of supported credentials is 32.
