Install the exact s/w versions and follow the steps provided.
Use a module with at least 1MB flash memory and you should be fine.

- Fri Dec 04, 2015 4:39 am #35623 I'm having an issue where I don't see the my ESP in the Arduino IDE port selection menu. I created an entry in my hosts file and mapped COM35 to the apropriate IP and OTA flashing works, awesome!

Is there a command line dns-sd or similar i can use to find my ESP's and see if its my IDE or ESP thats acting up?

- Sat Dec 05, 2015 8:03 am #35714 So i finally found the magic use of dns-sd, and i spot my arduinos fine on the command line. They do not show up in my IDE. 1.6.5 with esp8266 2.0.0 from board manager. Any tips?

- Thu Dec 10, 2015 7:11 am #36153 Hi,

I'm using Linux. OTA works o.k. with the firewall disabled.
I would like to enable my firewall, but what port(s) should I leave open ?

Regards,
Elmar
