Part Number: CC2538
Other Parts Discussed in Thread: Z-STACK

Hello,

1) Is there any feature in z-stack to detect the jamming attack ?

2) I have enabled multiple channel in z-stack, in case of jamming attack suppose current working channel is jammed then, does the network has capability to switch to the other channel automatically? Or we have to switch to the other channel manually.

    1. You can refer to MT_SYS_JAMMER_FEATURE
    2. As I know, Z-Stack enable frequency agility and if there is jamming attach. Z-Stack should try to change channel. However, the original channel is jammed and I don't think all of your router/device would receive channel change request. I think this might cause some problem.

    1) do we have to set this "MT_SYS_JAMMER_FEATURE" during pre processor flag only.
    2) how this feature works?
    3) we need to enable in all three configuration znp,zr,zed?
    4) is this feature available in z-stack 1.2.2a for end device also?

    1. Yes
    2. It would detect jamming by scan current current channel and if there is jamming, it will send MT command.
    3. We usually enable it on ZC only.
    4. I remember it is.
