About ACK of transmission

Hi All,

In zstack, How can I transmit some packet without any ACK. For example, I wanna transmit a packet from 0x796F to 0x7970, But if I remove all ACK, then the packet only transmit from 0x796F to 0x0000. What should I do?

Thank you very much!

Only ZigBee PRO supports asymmetric links (transmit or receive only). All other versions of the ZigBee stack require the MAC layer acknowledgement to occur.

Hi Scott,

Is this possible to modify some bits in MAC ACK? I want to use the reserve bits to do some work.

Thank you!

I can't see how. MAC ACKs are completely automatic.
