Hey, very nice job!
I was looking on doing something similar for a battery powered device (M5 Paper) in order to build a portable dynamic remote for the stuff in the house.
In the blog post (https://blog.voneicken.com/2018/lp-wifi-esp32-pushed/) you mention that one of the changes is:
remove the ACK delay in LwIP (this will have negative effects on high bandwidth connections)
How did you manage to do this? I don't see a config flag in lwip.
Did you fork the esp component into your own repo?
Thanks
hi man, have you ever tested the current of every scheme in your board?
I left following message on your blog but then realized you are not active there since December so I am copying it here:
Most detailed analysis I have seen on internet for ESP8266 wifi connection.Thankyoufor your analysis. I wrote some basic code for my need to build low power sensor network using ESP8266 devices. They are performing very well (under 60 milliseconds for 1 way communication and around 125 milliseconds for 2 way communication). I will very much appreciate your analysis of code and your feedback so possibly I can improve the code. It is very simple setup with receiver and sender sketches communicating with each other. Please look at my code at:

Thanks.
I think there is an error in the sketch "esp32-deep-sleep-mqtts", at the top you define the MQTT port but then it's hardcoded below, took me some minutes figuring out why it was not connecting to my server.
#define MQTT_PORT 8883
mqtt.setServer(srvip, 8883);
