Chip: CC2530
Z-Stack: 2.5.1.a
When all channels turnned on and in an environment with more than one network, the ZigBee end device could possiblly never join the intended (the one you want) network, this is the nature shortcoming of Z-Stack 2.5.1.a, especially when the intended network is of low signal and the un-intended network is of better signal quality. To design the joining process more realiable, the end device must fix this issue. I stuied this issue almost one week and finally solved it with a good solution. I believe anyone using CC2530 and Z-Stack 2.5.1.a will have this issue, so If you want to fix it in your project, just contact with me. my email address: 30331471@qq.com
