In Z-stack, how the software to guarantee the acknowledgment frames can be transmitted in time?
As mentioned In CC253X User Guide, Acknowledgment frames can only be transmitted immediately after frame reception. The transmission timing is controlled by the FSMCTRL.SLOTTED_ACK bit. In Figure 21-15, we can got the maximum time used to transmit ACK is 12 Sysbol (about 192us). So, whether the Rx interrupt handler(rxStartIsr in Mac_rx.c) must complete the ACK transmission in 192us, and how can we guarantee that ?
