ResourceID Classes

Category Resource ID Range Description Operations
Common Resources 0 - 2047 Common resource defined inside Objects. Inside of an Object the resourceIDs must be unique but it can be reused in different Objects. -- --
Reusable Resources 2048 - 26240 Resources registered by companies, standards organisations or alliances. Note: ResourceID is finally allocated by OMNA Staff. Private registrations are not allowed
Private Resources 26241 - 32768 Private resource range, no registration is necessary and open to re-use. -- --

Description
4000ObjectInstanceHandleRObjlnkOMAThe object link is used to refer an Instance of a given Object. An Object link value is composed of two concatenated 16-bit unsigned integers following the Network Byte Order convention. The Most Significant Halfword is an Object ID, the Least Significant Halfword is an Object Instance ID. An Object Link referencing no Object Instance will contain the concatenation of 2 MAX-ID values.
4001ObjectVersionRStringOMALWM2M Object versioning label.
4010LogClassRWInteger255OMA Define the Log Event Class: 0: generic (default) 1: system 2: security 3: event 4: trace 5: panic 6: charging [7-99]: reserved [100-255]: vendor specific
4011LogStartEOMAActions:a) Start data collection(DC)b) LogStatus is set to 0 (running)c) DC is emptied (default) or extended according arg'0' value Arguments definitions are described in the table below.
4012LogStopEOMAActions: a) Stop data collection(DC) b) 1st LSB of LogStatus is set to "1"(stopped) c) DC is kept (default) or emptied according arg'0' value Arguments definitions are described in the table below.
4013LogStatusRInteger8-BitsOMAData Collection process status: Each bit of this Resource Instance value defines specific status: 1st LSB 0=running, 1=stopped 2nd LSB 1=LogData contains Valid Data 0=LogData doesn't contain Valid Data 3rd LSB 1=Error occurred during Data Collection 0=No error [4th -7th ] LSB:reserved 8th LSB: vendor specific.
4014LogDataROpaqueOMARead Access on that Resource returns the Data Collection associated to the current Object Instance.
4015LogDataFormatRWInteger255OMA when set by the Server, this Resource indicates to the Client, what is the Server preferred data format to use when the LogData Resource is returned. when retrieved by the Server, this Resource indicates which specific data format is used when the LogData Resource is returned to the Server 0 or Resource not present : no specific data format (sequence of bytes)1 : OMA-LwM2M TLV format2 : OMA-LwM2M JSON format3: OMA-LwM2M CBOR format[4..99] reserved [100..255] vendor specific data format
4016LogDataIncremental OpaqueOMALog data collected since the last Send operation described for the LogDataIncremental Minimum Send Interval resource, or since that interval has been set to a positive value if the first Send operation has not yet been performed. The data shall have the same format as the LogData resource, but its collection and emptying is independent from it and from the LogStart/LogStop logic. This resource may only be included in a Send operation payload. Attempting to access it via the Device Management and Service Enablement Interface shall result in generating the Method Not Allowed error.
4017LogDataIncrementalMinimumSendIntervalRWUnsigned IntegerOMAMinimum number of seconds between consecutive Send operations containing the LogDataIncremental resource. If this resource is zero or not present, then LogDataIncremental shall never be sent in a Send operation. If set to a positive number, a Send operation containing the LogDataIncremental resource shall be performed after the specified number of seconds since the previous one or when a new log information is generated, whichever happens later, and the data collection shall be atomically emptied upon successful delivery. If the LwM2M client is connected to multiple servers, this resource SHOULD be handled independently for each server.
