How to set a particular channel for cc2530

Other Parts Discussed in Thread: CC2530

I'm using cc2530 with Sampleapp, I use a Coordinator and an End-device. I watched that when End-device begin start , it will search The Coordinator for about 3 seconds, at this duration the current consume will maintain at about 26ma, I want save these energy consume, I thought when ZMacInit() is executed cc2530 is scan idle channels，it will takes some time and waste energy in my application area, so I try to set a particular channel use MAC_MlmeSetReq(MAC_LOGICAL_CHANNEL,&Particular_channel), But I can not find any result after use this function, I also try to use it before ZMacInit() and after ZMacInit(), and I watched MAC_MlmeGetReq(MAC_LOGICAL_CHANNEL,&channel_get) get the same channel No(I use debug and watched it's always 0X0B).

How can I set a particular channel for cc2530,Or how can I shorter the duration of ZmacInit()?

Hey,

You can set a specific channel (and PANID) while compilation of a project.

Open f8wConfig.cfg file, then find the channels list and uncomment one you like

Thank you for you answer,I checked my f8wConfig.cfg and I find in my .cfg CHANLIST was set 0x0B channel and PAN_ID also be set to 0x1105.So my question is answered but How can I short the connecting time? Can I change it from 3 seconds to 1 seconds or less?

Dears,

What do you mean by shorten the connecting time? Do you mean the time needed to join coordinator?

Dears,

You can change NUM_DISC_ATTEMPTS in ZDApp.c from 3 to 0. This will shorten the joining time. However, this value should be 3 according to ZB spec.

Yikai,

I changed NUM_DISC_ATTEMPTS which in ZDapp.h as you said , it become effective immediately, connection time from 3-5(Previously about 5 seconds) seconds shorten to about 2 seconds, Thank you very much .

Is there any other parameters that can shorten connection time?

Best Regards!

Dears,

Do you enable security in you ZB network? If you disable it, it should be shorter.

YiKai,

Thank you for your further answers，I checked my f8wconfig.cfg file ,there are already have '-DSECURE=0', it's means there are no security.

If anybody tried other parameter, could you tell me? I'll also try other parameters myself,If I have any progress,I'll post here.

Hi yikai
could you please tell me where is the define of NUM_DISC_ATTEMPTS value in Zigbee spec？
i found that was defined as 2 in zstack 2.6.2 ， is that shortest？

No, it is not shortest. You can set NUM_DISC_ATTEMPTS to 0 in ZDApp.c

By the way, it is defined by ScanAttempts in section 5.3.2 Join Parameters of Zigbee HA profile spec.
