Re: Calling experienced network programmers

The ESP8266 has a 1460 byte send buffer and it is fairly aggressive about waiting on ACKs. I'm not familiar with the background here, so I may be way off base, but it sounds to me that you're might be using the wrong tool for the job. TCP is a streaming protocol. You use it when you need to p-t-p tr...

Re: NEW: WiPy 2.0 - shipping 10 Oct 2016

The ESP32 underlying it quotes 21dBm max transmit and -98dBm receive (DSSS @1Mbps). Using a naive calculation of free space loss based on: -L = 32.5 + 20 * log(1) + 20 * log(2415) solves -L ~100dBm therefore with ideal conditions 1km might be achieved with a typical ~-15dB margin if antenna gain/los...
