CC2538: ZED to ZED command send

I want to bind "0xA3A8" and "0x3904"
Thank you

So, both "0xA3A8" and "0x3904" should send ZDP_EndDeviceBindReq in 15 seconds windows.

Hi chen,

I made as you told, the capture saying 2 ZED's successfully binded. Please check.03.rar

And is there any way to increase the 15sec  to more

You can change APS_DEFAULT_MAXBINDING_TIME to do it.

Hi Chen,
In case ZED1 is binded with ZED2, ZED3 and ZED4. How to send commands to all three induvisualy.
You told "AddrNotPresent" mode will send data to Binded device. When binded with different devices how to differentiate.
Thank you

If you bind ZED1 to ZED2, ZED3, and ZeD4 and use AddrNotPresent to send message, Z-Stack would go to binding table and find those three destinations to send message automatically.

In the same scenario I want send from ZED1 to ZED2, ZED1 to ZED3 and ZED1 to ZED4 with different data separately. Is it possible with AddrNotPresent . Is it any wrathful, use of AddrNotPresent over Addr16bit.

If you bind them with different clusters, you can send different messages with AddrNotPresent using different cluster ID.

Hi chen,
do you mean inclusters and outclusters sending during binding request.
If it is, is there any rule to maintain clusters. I mean Incluster of Binding request should match Outcluster of binding respond device like that.
Thank you.

Hi Chen,
Lets take ZED1 is Binded with ZED2 with
static cId_t OutClusters2[] =
{
ZCL_CLUSTER_ID_GEN_ON_OFF
}
static cId_t InClusters2[] =
{
ZCL_CLUSTER_ID_GEN_ON_OFF
}

binded with ZED3 with
static cId_t OutClusters3[] =
{
ZCL_CLUSTER_ID_GEN_ON_OFF
}
static cId_t InClusters3[] =
{
ZCL_CLUSTER_ID_GEN_ON_OFF
}

Then while sending command using AddrNotPresent, how will my ZED1 decide whom to send ZED2 or ZED3
Eg:
afAddrType_t abc;
abc.addrMode = (afAddrMode_t)AddrNotPresent;
zclGeneral_SendOnOff_CmdToggle( SAMPLESW_ENDPOINT, &abc, FALSE, bdb_getZCLFrameCounter() );

Thank you

If you binding ZED1 to both ZED2 and ZED3, AddrNotPresent would send messages to both ZED2 and ZED3.

In the same I want to send only from ZED1 to ZED2 and not ZED3 is it possible in AddrNotPresent.
So I think Binding is useful in network like Master and Slave network with master as to send command to all slaves and slave can send only to master or its slaves. Its helps in send command to multiple devices in network at a time

Thank you Chen

Binding is nothing like master/slave. Binding just test device where to send message so it you binding ZED1 to multiple devices, it would send message to all of them when you use AddrNotPresent.

Chen without using binding and AddrNotPresent is there any other way to send command to multiple devices

If you know destination short address and endpoint, you can send message to destination one by one.

Ok, fine all at a time is no possible without binding is it.
And in binding one at a time is not possible in more than one binds, am I write

To control all ON/OFF devices, you can use group cast if you add them to the same group.

Hi Chen,
How to achieve this group cast, is it work between all the devices in network irrespective of the type of device(ZR/ZED/ZC).
Thank you for great support.

You can use API aps_AddGroup on device to add the device to specific group and group cast only works on receriver always on device.

Plese brief this,
group cast only works on receriver always on device

Groupcast actually uses broadcast mechanism so if the receiver is not always on, the message might not be received by device. Receiver always on device includes ZC, ZR and you can configure a ZED to receiver always on.

Hi Chen,
"aps_AddGroup " is not found in application anywhere.
As well please clarify me,
Can I create a group in ZED?
Can I mix ZED, ZR and ZC in group?
How many groups can be made in 1 device?

thank you

You have to include aps_group.h to use API aps_AddGroup and Yes, you can mix ZC, ZR, and ZED in the same group. The max number of group is defined by APS_MAX_GROUPS in f8wconfig.cfg and the default value is 16.

Hi chen,
If I create the group,

aps_Group_t group1;
group1.ID = 0x0001;
group1.name = "mixedgroup1";
uint8 endpoint = zclSampleSw_DstAddr.endPoint;

then which all devices call this,
aps_AddGroup(endpoint , group1);

Eg: ZED1, ZED2, ZC, ZR1 and ZR2 all are called the same function with same params, then all these are in "group1". So if I sent anything to this group1 from ZED1 all others will receive

Is my understand is correct, or anything else please clarify me.
if it is write, is it need of initialization by calling any of "aps_GroupsInitNV" or "aps_GroupsSetDefaultNV"

Thank you

Yes, it's correct and no need of initialization by calling any of "aps_GroupsInitNV" or "aps_GroupsSetDefaultNV"

Hi Chen,
Is it need to be cal at start or after Connected to network

I couldn't understand your question well. Can you elaborate what to cal?

Hi chen,
To add the device to group,
aps_AddGroup(endpoint , group1);
is to be call on start of application or after connected with any coordinator network

It can be called after connected.

Hi Chen,
Cal to "aps_AddGroup()" to add the device to group is once after connect to network is enough or on Reconnect on Restart/Failure time also has to cal.

Thank you

Adding the device to group once after connect to network is enough.

Hi Chen,
I added my ZED to group. So, I can read the group info also after added.
My devices are ZED, how to make Receiver always ON in ZED?
After that how to send "Cluster Commands / String msg" to the group?

Thank you

1. Define "RFD_RCVC_ALWAYS_ON=TRUE" in ZED compile option to make it as receiver-always-on device
2. You can set address mode to AddrGroup and assign group ID in destination address to send group message.

Hi Chen,
I trued to send Msg as below and getting Unknown Af_Status,

char *groupBuf = "Hi group members";
endPointDesc_t *groupepDesc;
afAddrType_t groupdstAddr;
cId_t groupcId;
uint8 grouptransId, grouptxOpts, groupradius;
uint16 groupdataLen;
uint8 groupretValue = ZFailure;

groupepDesc->endPoint = SAMPLESW_ENDPOINT;
groupepDesc->latencyReq = 0;
groupepDesc->epType = ZG_BUILD_ENDDEVICE_TYPE;

groupdstAddr.addrMode = AddrGroup ;
groupdstAddr.addr.shortAddr = 0x0001; //0x0001 is group ID

groupcId = osal_build_uint16( groupBuf );

grouptransId = 1;

grouptxOpts = 1;

groupradius = AF_DEFAULT_RADIUS;

groupdataLen = strlen(groupBuf);

groupretValue = AF_DataRequest(&groupdstAddr, groupepDesc, groupcId,\
groupdataLen, groupBuf, &grouptransId, grouptxOpts, groupradius);



Thank you

What is Unknown Af_Status?

Return of AF_DataRequest(),
groupretValue = AF_DataRequest(&groupdstAddr, groupepDesc, groupcId,\
groupdataLen, groupBuf, &grouptransId, grouptxOpts, groupradius);

On call to send data with above parameters "AF_DataRequest " is returning none of its know values like its not "afStatus_SUCCESS or afStatus_FAILED or afStatus_INVALID_PARAMETER afStatus_MEM_FAIL or afStatus_NO_ROUTE"

So I named it Unknown Status

So, what is the groupretValue you get exactly?

getting '0' on cal to "aps_AddGroup()" after connected with ZC with group ID= 0x00001 and groupname

0 means success.

ABC.zipCBA.zip

Hi Chen,
I think now its sending and receiving fine, please check the attached Captures.
ABC capture is without adding "group Id" as short address
BCA is adding "group Id" has short address

Its seems both doing same.
If sending to group is fine, is group is the only parameter to differ the group of interest to send ?

Yes, group ID is the only difference.

Hi Chen,
But I am not receiving my message at receiver end with "AddrGroup", the same with "Addr16Bit" getting fine.
Please can you see once again why I am not receiving at the other ZED's of same group

Thank you

Are you sure your ZED is set to RX always on?

Yes I am sure,
I defined "RFD_RCVC_ALWAYS_ON=TRUE" and flashed the same application to both ZED

Hi chen,
In application how to check RX always on or not?

Thank you

Can you specify your ZED short address in your sniffer log?

Sending from : 547C
Receiving end : 7247

Both are in group of groupId "0x0001"

Hi chen,
In capture it seems that msg is reaching from "0x547C" to Co-ordinator "0x0000", but co-coordinator is trying to send to "0xFFFF" instead of group member "0x7242"

One more thing I added only "0x547C"and "0x7242" to the group not added Co-ordinator to groupId 0x0001
Thank you

Both of 547C and 7247 are not RX always on device.
