Hi Sir:

 

Now I am using JN5161, and using AN1219 (v1007) to develop a Zigbee green power switch..

I found a strange problem.. 

When i using security level 3, means  "GPD_SECURITY_LEVEL_FC_4B_MIC_4B_WITH_ENC", and the actuator designed by Silabs MG21 can receive the commissioning and toggle telegram send from switch.

But when i using security level 2, means "GPD_SECURITY_LEVEL_FC_4B_MIC_4B_NO_ENC", the same actuator can only receive commissioning telegram, and have no response with toggle telegram.

I guess MG21 ignored the toggle telegram because something is wrong..

 

The question is why it happens? Thanks.
