RTOS/LAUNCHXL-CC2650: Problem in End device (CC2650) joining with Coordinator (CC2530)

Part Number: LAUNCHXL-CC2650
Other Parts Discussed in Thread: CC2530, CC2650, Z-STACK

Tool/software: TI-RTOS

Hello Members,

I've Launchxl-cc2650 acting as a End device and CC2530 as a coordinator. I am running Sampleswitch example for Zstack testing. The coordinator has formed the network and End device is able to discover the network.

For joining, I've disabled the TC-link key security at the coordinator end (just for debug purpose). The End device is initiating the joining connection to the coordiantor but every time It failed to join.

These are the line of code which is showing the network joining request:

In Zstart.c file, @fn zstack_ZStatusValues Zstart_join(void)

ret = Zstackapi_DevJoinReq(params.entityID, &join);
            
            if(ret == zstack_ZStatusValues_ZSuccess)
            {
                params.state = ZSTART_STATE_JOINING;
            }
            else
            {
                params.state = ZSTART_STATE_HOLD;
            }

            return(ret);

It returns params.state as ZSTART_STATE_HOLD and start the z stack again. Does the sampleswitch application also support any kind of security as I am not able to join the network? I've read all three documentation from TI (Zstack home dev guide etc.) but didn't find much information regarding joining and security at CC2650 end. Please guide me in right direction.

Apologies if I am not able to explain things properly. I'll try to explain more if require.

With Regards,

Priya

I you had disabled the TC-link key security at the coordinator end, you have to disable it on CC2650 too.

Hi,

Thank you for your quick response. I have disabled the security at CC2650 end too. But it is still not getting joined.

Try to set -DSECURE=0 in f8wconfig.cfg on both ZC and ZED to test again.

Again thanks for your support and so quick response.
I've done the same thing you're saying. This is the way I've disabled the security and removed the definition of TC_LINKKEY_JOIN from Project->Options->C/C++ Compiler -> Preprocessor -> Defined symbols.

Make sure you rebuild everything and erase whole flash on CC2530/CC2650 before you download new built FWs.

I've erased the flash, rebuilt the zstackcore and sampleswitch application again and download them in CC2650 and debugging. I've done same thing with CC2530. But with no luck, failed to join :(

I suggest you to setup sniffer to check what happens over the air.

Can you please help me in one thing. I wanted to see the status of the responses Zstack thread is giving. Can I print the status of the enum? If not, How can I see the status of the responses.

An example is

 // Was the response successful
            if(errno == ICALL_ERRNO_SUCCESS)
            {
                // setup return of
                status = (zstack_ZStatusValues)pMsg->hdr.status;
            }
            else
            {
                // Translate ICall Error status to ZStack API status
                if(errno == ICALL_ERRNO_NOMSG)
                {
                    status = zstack_ZStatusValues_ZIcallNoMsg;
                }
                else if(errno == ICALL_ERRNO_TIMEOUT)
                {
                    status = zstack_ZStatusValues_ZIcallTimeout;
                }

I'm seeing errno as successful so I want to print the status from

status = (zstack_ZStatusValues)pMsg->hdr.status;

How can I see what status it is showing?

Sure. I'll test with packet sniffer and will get back to you soon with my inputs.
Thank you for your time and guidance.

If you have sniffer log, you can attach it.

Priya, as YK had mentioned, once you we have a sniffer log for reference, it will be much more useful.

As you said you had read several documents, hopefully you have also looked into using the porting guide for the CC2650: processors.wiki.ti.com/.../CC2650_LaunchPad_User's_Guide_for_ZigBee

Best,
Sean

Hi YK and Sean,

Sorry for the late response. Actually, I am using packet sniffer for the first time so tried to understand the basic behavior of packets.

Please find attached the PSD data log file (3426.Packet_sniff_data_1.psd) and let me know what is happening OTA.

@Sean Yes, I've seen it earlier and used it as well. But right now for Zstack implementation, I am just using the already installed examples. I've called the function Zstart_discovery without having dependency of switch. Please suggest me if I am dong wrong.

Thank you in advance.

Priya,

I'm assuming you are using Z-Stack 3.0.1, have you tried simply running the Light/Switch examples straight out of the box without disabling TC-Link security? From the looks of your sniffer log, I'm not entirely sure if the network is being opened properly as there is constant NwkOpen's with the same sequence # being sent out.

Also, what are you trying to do exactly without having the switch dependency?

Best,
Sean

I only see orphan notification and beacon requests in your 3426.Packet_sniff_data_1.psd and there is not any response from coordinator. Are you sure your coordinator is turn on and working?

Hi Sean and Yikai,

Thank you for your kind responses and point me in right direction. You guys were right, my coordinator was not working at that time. I uninstalled things and installed everything from scratch and I now able to see the successful association request.

Please see my PSD file updated_packet_sniffer_data.psdand let me know if anything is going wrong. I am able to see the data request now which means the end device has joined the coordinator. Right?

Glad to hear you were able to resolve your issue.

Yes, I can see that the ZED was able to successfully join the ZC's network, and the ZED starting polling its parent (the ZC).
