CC2530: Could we change CC2530's channel once the network is created?

Try to refer to discussions in e2e.ti.com/.../3194809

Hi Yikai,

    According to your reply in the thread, there is no ZNP/MT command could be used from the host CPU to change channel after the network is created. If I don't create the proprietary ZNP/MT command, the only way to configure channel is using SYS_OSAL_NV_WRITE to set channel mask. Is it correct?

    One more question. I had tried to set the primary channel mask to 0x0000F000 to request CC2530 to create network using channel from 12 ~ 15 by the "APP_CNF_BDB_SET_CHANNEL" command. However, the channel number read back by the "ZDO_EXT_NWK_INFO" coomand is 24. What's wrong with my setup procedure?

    Thanks.

1. Yes, the only way to configure channel is using SYS_OSAL_NV_WRITE to set channel mask if you don't create the proprietary ZNP/MT command.

2. Do you set secondary channel to 0?

Hi Yikai,

    Yes, I set the secondary channel mask to 0.

    Thanks.

Can you show my how you set primary channel?

So, your problem is that you don’t do factory reset to your device to make new settings work.
