Zigbee SDK 3.7.1.2 reporting issue

wes58

AFter changing from SDK ver 3.6.8.1 to 3.7.1.2 I have noticed that I had an issue with reporting. The reports were working fine for many years but now the reports are sent continuoulsy even though the value didn't change, and I can't access the chip.
I have the reports configured (as in all your sample projects)

/* Set default reporting configuration */

    u8 reportableChange = 0x00;

    bdb_defaultReportingCfg(SAMPLE_LIGHT_ENDPOINT, HA_PROFILE_ID, ZCL_CLUSTER_GEN_ON_OFF, ZCL_ATTRID_ONOFF,

                            0x0000, 0x003c, (u8 *)&reportableChange);

After checking the code in old and new SDK I found the following in the zcl_reporting.c

SDK ver 3.6.8.1

_CODE_ZCL_ bool reportableChangeValueChk(u8 dataType, u8 *curValue, u8 *prevValue, u8 *reportableChange)

{

    bool needReport = FALSE;



    switch(dataType)

    {

        case ZCL_DATA_TYPE_UINT8:

            {

                u8 P = prevValue[0];

                u8 C = curValue[0];

                u8 R = reportableChange[0];

                if(P >= C){

                    needReport = ((P - C) > R) ? TRUE : FALSE;

                }else{

                    needReport = ((C - P) > R) ? TRUE : FALSE;

                }

            }

            break;

And in SDK ver 3.7.1.2

_CODE_ZCL_ bool reportableChangeValueChk(u8 dataType, u8 *curValue, u8 *prevValue, u8 *reportableChange)

{

    bool needReport = FALSE;



    switch(dataType)

    {

        case ZCL_DATA_TYPE_UINT8:

            {

                u8 P = prevValue[0];

                u8 C = curValue[0];

                u8 R = reportableChange[0];

                if(P >= C){

                    needReport = ((P - C) >= R) ? TRUE : FALSE;

                }else{

                    needReport = ((C - P) >= R) ? TRUE : FALSE;

                }

            }

            break;

        case ZCL_DATA_TYPE_UINT16:

So now, when reportableChange = 0, and no change in previous and current values of data, the reports are sent continuously. Before it had to be greater than reportableChange for the report to be sent.
And what is interesting, in ZigBee SDK developer manual, in section 5.2.6 it says

5.2.6 bdb_defaultReportingCfg()
Configure the default reporting message, which takes effect after binding.
Prototype
status_t bdb_defaultReportingCfg(u8 endpoint, u16 profileID,
u16 clusterID, u16 attrID,
u16 minReportInt, u16 maxReportInt,
u8 *reportableChange)
Return value
ZCL_STA
Name                 Type   Description
endpoint              u8     Endpoint.
profileID              u16   Profile Identifier.
clusterID              u16   Cluster Identifier.
attrID                  u16   Attribute Identifier.
minReportInt        u16   Minimum reporting interval, in seconds.
maxReportInt       u16   Maximum reporting interval, in seconds.
reportableChange  u8*  Reportable change (only applicable to analog data type).

So reportable change should only be appicable to analog data type!

Hi,

This issue is fix in v3.7.1.2.

Thank you.
You should say it was fixed in "V3.7.1.2_Patch_0001"
I had V3.7.1.2 downloaded in December last year with this issue!
