ESP8266 not discoverable for OTA (Arduino)
Posted: Sat May 02, 2020 7:17 amDear Sirs, I updated my Arduino installation to the latest ESP8266 Arduino Core, today's release 2.7.0 and I recompile (without making any change) and upload one of my projects for testing. All seems fine, with the exception of OTA via Arduino (1.8.12). I lost the device under testing (D.U.T. that is a ESP8266 based board) from Arduino Network ports. I tried everything as: power off / on the D.U.T. restart my host computer (Windows 10), restart my WiFi router... Nothing seems to work. Only I noticed that the D.U.T. show up to Arduino Network ports (and exactly the same, to my Bonjour browser that is running at my host computer) just after the D.U.T. Restart and a couple of minutes later is again, lost permanently. Please be noted that in this testing, I have not change something and my last compilation of this Sketch / project was a month ago (with Core updated form git master) without this problem. What can be wrong? I am suspecting some changes that recently be done to mDNS and to supporting interfaces... Please let me know what to do / check or what the solution could be. Thanks.
