stack event : ZPS_EVENT_NWK_FAILED_TO_START

[wslee]

* Environment : JN5169, JN-SW-4168, Coordinator, RF Channel(11,14,15,19,20,24)

When the coordinator started with ZPS_eAplZdoStartStack () in some circumstances , It meets stack event ZPS_EVENT_NWK_FAILED_TO_START. 

That circumstances is several WiFi routers around.

If I turned off several WiFi routers around, ZPS_EVENT_NWK_STARTED is generated.

Is there a good solution without turning off the WiFi router around?

Hi Lee,

I suggest you to switch you application to channels where is not overlapped with typical Wi-Fi spectrum. Hopefully, this will make your network can co-exists even though you have several Wi-Fi routers around.

802.15.4 open channels when Wi-Fi fully utilized the band: 15, 20, 25 and 26.

I hope this helps.

Best regards,
Felipe

Hi Felipe,

I have tested but that channel is sometimes occurs  event ZPS_EVENT_NWK_FAILED_TO_START.

Is it possible to set the channel manually if an event occurs ZPS_EVENT_NWK_FAILED_TO_START?

Best regards,

Lee

Hi Lee,

Yes, it is possible to change your network channel. You can configure that in bdb_options.h.

Hi Felipe,

Where is bdb_options.h?

I am using JN-SW-4168-SDK - JN516x ZigBee Home Automation SDK.

Hi Lee,

In Home Automation SDK you can look in JN-AN-1184 Router example. Using that AN you can change the channel in  app_router.c file and vStartup function.

What AN are you using?

Best regards,

Hi Felipe,

I am using JN-AN-1189 example.

And I will test with vStartup function source of JN-AN-1184 Router example.

Thanks.
