Time slicing operation results are unstable #371

Closed Aniwer closed 3 months ago

Aniwer commented 10 months ago

Hardware：Xilinx zedboard + FMCOMMS3

  1. By setting both slice_start and slice_end of slice 0 to 0, STA disconnects from openwifi and cannot scan openwifi.(I think queue 0 cannot send out beacon frames and probe response frames in this way, which is in line with expectations.)
  2. By operating slice 2 as described in step 1, STA can scan to openwifi, but will be refused association by openwifi.(This is why I don't quite understand)
  3. When I operate as described in the documentation https://doc.ilabt.imec.be/ilabt/wilab/tutorials/openwifi.html#sdr-tx-time-slicing, the situation is not stable and sometimes there is no change , sometimes openwifi cannot be scanned

So I have some questions： Does SDR TX 4 queues correspond to the EDCA mechanism?（The video link in the document seems to be broken） Does setting slice_start and slice_end to 0 mean closing the tx_queue?
