Hi all, I am trying to send a frame exactly SIFS after one DTIM. I've seen that the PS broadcast traffic should make something similar. If I try to follow the same procedure I get some DMA errors. I would like to understand much better all this things but I am not able to find more information about the tx descriptors and how the tx works. Could someone give me some advice on where to get more details?
