Injection speed? #101

Open rodizio1 opened 7 years ago

rodizio1 commented 7 years ago

I have just succesfully compiled and installed nexmon on a Raspberry Pi3 Raspbian 2017-06-21 Kernel 4.9.28.

Injection seems to work, however it's quite slow and unsteady, maximum injection speed is roughly about 300kbytes/s, regardless of datarate used.

Is there any way to get higher injection speeds?

You can always inject at the fastest injection speed by creating frames directly in the firmware. Unfortunately, our hack in the brcmfmac driver might not be the best to achieve high injection speeds. If you have some time, you could try to figure out the bottle neck, which should likely be somewhere in the driver. And then you could share your results.
