华为海思NB_IoT模组，657版本AT指令集Contact us110第5页共110页1 IntroductionThis document gives details of the AT Command Set supported by the hisiHi2110 chip loaded with v100R100C20B657 and v150R100C10B120 firmwareAt boot the following string will be outputNeul OK After this string has been received the AT Command processor is ready toaccept at commandsIf the Applications core was rebooted or restarted forany reason that wasn't anoormal power-on sequence, a message will be output before theNeul< CR>OK string. See Chapter 7 for more detailsIn case external MCU intervene the process of update, unsolicited informationinforms the external MCU update state Please reference AT document [l] for more detailinformation FIRMWARE DOWNLOADINGIndicates UE is downloadingpdate package FIRMWARE DOWNLOAD FAILED< CR> Indicates download failed FIRMWARE DOWNLOADEDIndicates download finishedFIRMWARE UPDATING Indicates UE is updatingFIRMWARE UPDATE SUCCESSIndicates update success, butnot report update statefirmware package server yet第6页共110页 FIRMWARE UPDATE FAILED Indicates UE update fail FIRMWARE UPDATE OVERIndicatesreportedupdate state to firmwarepackage server.During FOTA procedure, device shouldn' t operate modem until FIRMWARE UPDATEOVER" is reportedE.g.

A new-line character is ignored so it is permissible to usecarriage-return line-feed pairs on the inputno command is entered after the at token ok wilk be returned. if an invalidcommand is entered error will be returnedOptional parameters, unless explicitly stated, need to be provided up to the lastparameter being entered1.3 AT Command ResponsesWhen the AT Command processor has finished processing a line it will output eitherOK, ERROR or an error code indicating that it is ready to accept a new commandSolicited informational responses are sent before the final ok or ERROR. Unsolicitedinformation responses will never occur between a solicited informational response andthe final ok or errorFor AT Commands aligned to the 3Gpp 27.007 specification error codes are enabledwith the CMEE command, else the ERROR message will be returned For AT Commandsaligned to the ETSI 127.005 specification, a CMS error will be returned where specifiedCMS error will be returned where specified第8页共110页Responses will be of the format+CMD1: OKOK1.4 3GPP Alignment3GPP commands are aligned to 3GPP TS 27.007 v14.3.0 (2017-03) For clarificationon 3GPP commands, please refer to this document.1.5 Modification HistoryD。 cument IpFirmware ModificationReleaseV100R100C00B350Output how uses before and after each lineIssue 2B350SP13of outputPreviously only the trailing was generatedV100R100C00B350Issue2B350SP13Error behaviour aligned to +Cmee=o has beenimplemented.
