"Thanks for the results! How exactly did you measure the latency? Using the stopwatch+screenshot approach?
Currently I'm diving into the main source for the latency. So far I've found that there are most likely no frames "stuck" in the raspi encoder…"
"I looked into that issue and resolved a sharp edge from tx. It wasn't catching EOF at input, leading to zero sizes packets being flooded at maximum rate. That's why you observed 0B/s at the rx side. If you pull from my repo you'll get the patch."
"Could you please show us as well the output of tx right at the beginning? It might be a problem with your video data from raspivid. Your high tx rate reminds me a bit of an effect that occurs when the data source process (in this case raspivid)…"
"Patching the kernel definitely helps increasing the range. I made the instructions on my page a bit more clear on that point. By default the patch sets the output power to 20dBm. Depending on your country and hardware you could set this value…"
"The range tests on my blog (except the very first ones) are made with the Alfa as tx. With that I could reach 900m omni2omni and 3km+ omni2doublebiquad. with two wn722n I reached 300m (more or less) omni2omni and 1km with omni2doublebiquad."
