DNS_SD_Arduino_OTA No response from device

[dariocdj]

Hi guys,
i'm using arduino 1.6.5 with staging esp core 1.6.5-1160-gef26c5f
Windows XP
Firewall disabled, antivirus disabled
Python 2.7 in path
Sketch : DNS_SD_Arduino_OTA without any mod (only ssid and pass)
Esp-01 and Esp-12 tested.

Arduino IDE found port when i select Uploading Using OTA

When i try to open serial monitor it ask me for a password

If i open a shell i can ping regularry esp on 192.168.0.211

if i open a telnet client and try to connect to 192.168.0.211 port 8266 it seems to open connection (don't refuse it)

When i try to upload sketch:
python.exe C:\Documents and Settings\Cdj.SERVER\Dati applicazioni\Arduino15\packages\esp8266\hardware\esp8266\1.6.5-1160-gef26c5f/tools/espota.py -i 192.168.0.211 -p 8266 -f c:\temp\build6064416799227852722.tmp/DNS_SD_Arduino_OTA.cpp.bin

16:04:39 [ERROR]: No response from device

Thanks for helping

Well.. this is the mac address :
18:fe:34:a5:db:e5 esp8266
10:bf:48:7e:ea:24 pc with arduino ide

Attached you can find wireshark log

Thanks for helping !

Hi Dario,

I have just tried the same set up like yours except I have Windows 7:

Sketch uses 342,558 bytes (32%) of program storage space. Maximum is 1,044,464 bytes.
Global variables use 43,246 bytes (52%) of dynamic memory, leaving 38,674 bytes for local variables. Maximum is 81,920 bytes.
python.exe C:\Users\Krzysztof\AppData\Roaming\Arduino15\packages\esp8266\hardware\esp8266\1.6.5-1160-gef26c5f/tools/espota.py -i 192.168.1.11 -p 8266 -f C:\Users\KRZYSZ~1\AppData\Local\Temp\build8549792214206597213.tmp/DNS_SD_Arduino_OTA.cpp.bin
Uploading.............................................................................................................................................................................................................................................

Are you able to test it on Windows 7 machine?
At this point I do not have any better ideas.

No way... tried on Win 7 64bit with esp 1.6.5 stable core and esp 1.6.5 staging core but same result :

01:41:21 [ERROR]: No response from device

What version of phyton are you using? I'm using 2.7.10. What kind of esp ? How is it connected ? I don't have any ideas where to bang my head !
Thanks
Dario

Also tried to erase eeprom first....

Hi Dario,

I can’t believe how close you are to get this working and how simple should be the reason so it is not working 😄

Here is my python:

Python 2.7.10 (default, May 23 2015, 09:44:00) [MSC v.1500 64 bit (AMD64)] on win32

I am currently using NodeMCU boards, namely LoLin and Amica as well as ESP8266-EVB by Olimex.

All are working without any issues with DNS_SD_Arduino_OTA.ino and esp8266/Arduino release 1.6.5-1160-gef26c5f (of Sep 30, 2015).

I have been testing OTA back and forth when writing first three chapters of: https://github.com/esp8266/Arduino/blob/master/doc/ota_updates/ota_updates.md and was always getting repeatable results and stable operation of OTA. This is assuming I use compatible s/w on each step.

I am wondering if you see anything on serial monitor when OTA fails. If successful, the output on serial monitor looks like below:

Arduino OTA Test

If there are no clues on serial monitor and you are not moving any way forward I would put it aside for a while and try other way of doing OTA: https://github.com/esp8266/Arduino/blob/master/doc/ota_updates/ota_updates.md#web-browser. If this fails as well maybe the problem is with your Wi-Fi network / router.

Good luck and I am looking forward to seeing how you handle this issue 👍

Thank you for prompt answer, i 've forget something..... Serial monitor prompt me a password !!!

[krzychb]

Yes - you mentioned it in your first post 😄

I assume you selected network port to do OTA.
Then you try to open Serial Monitor in Arduino.
This will not work - Arduino Serial Monitor over network port is not implemented for ESP.

You need an external serial monitor.
If you do not have one I recommend http://www.compuphase.com/software_termite.htm

Krzysztof

P.S. Remember to close external serial monitor if you decide to flash module using Arduino's serial!

[dariocdj]

Ah ok perfect, dunno if I can try this w.e. But I want to find 10min to go in my lab and debug this!!! Thank you for helping

[dariocdj]

Ok Krzysztof, with an external serial monitor this error appear :

Arduino OTA Test
Sketch size: 346664
Free size: 90112
IP address: 192.168.0.211
Update Start: ip:192.168.0.2, port:48266, size:346672
Update Begin Error
....
thanks
Dario

Free size: 90112
That's way too small to fit 346672 bytes.
If you are selecting "Generic ESP8266 module" in Board menu, you need to select larger flash size (i.e. 4M).
Of course, your board must have more than 512k flash in order for this to work...

[dariocdj]

I test it immediately......thanks for prompt answer

[dariocdj]

i can't believe it !!!!!! IT WORKS !!! Thanks a lot to everybody !!!!

[dariocdj]

Ok guys, now esp-12 work fine, but esp-01 no....

flash size is correct... i've a Manufacturer: c8 Device: 4013 ESP-01 so 4mbit....

this is serial response :
