OTA - No Network port is shown ! #5273

Closed HamzaHajeir closed 6 years ago

HamzaHajeir commented 6 years ago

Hi guys. I've worked 2 days ago to flash my esp Over The Air. Uploaded BasicOTA official sketch, All things went fine. Tested file uploading with success.

Today I went to develop the code and merge it in a real project. but after i upload it by serial, Network port won't show anymore (Only Serial) !

So tried back to BasicOTA sketch, with no success.

I've dived into this topic and reached a good point to the final solution.

See @krzychb's response , I tried a similar command below, See results :

OTA uploading is success! but until now there's no Network port is shown at Arduino IDE.

I've restarted Arduino IDE many times with no success.

Platform

Hardware: [ESP8266 NodeMCU 1.0 v3]
Development Env: [Arduino IDE 1.8.7]
Operating System: [Windows 10 x64]

Settings in IDE

My esp8266's core is updated (2.4.2)

Thanks in advance Hamza Hajeir

After serial upload, did you physically reset the ESP (e.g.: press the reset button)?

HamzaHajeir commented 6 years ago

@devyte Yes i did many times.

Also tried to re-power it manually by re-plugging its usb cable.

Oh, it's windows. Did you disable the firewall, or at least set up a firewall rule? OTA works with the ESP's MDNS responder, which is UDP.

devyte commented 6 years ago

Also, closing as this is not an issue with the core.

HamzaHajeir commented 6 years ago

Yes I've fully disabled firewall and created rules that works with active firewall.

If i did not, it wouldn't flash OTA manually.

I'm having the same issue. Where should we report this issue?

devyte commented 5 years ago

It's already fixed post beta1: ArduinoOTA now calls MDNS.update() to maintain it, assuming begin() or begin(true).

peros550 commented 5 years ago

Please forgive my ignorance. I have been working the whole weekend troubleshooting why the OTA mechanism stopped working. It was a long time when I last used OTA and some (esp8266 boards) version updates were made but not tested.

Therefore, I was focusing on what my code did to break the OTA rather than the tools I used.

Finally, I have just found out that all versions (including the latest beta) post 2.3.0 have broken OTA functionality for me.

I am using Wemos D1 mini which has been renamed to Lolin.

Hi @peros550, I've tried to search for a solution. I've opened a thread at esp8266 forums.

But i didn't find the solution yet.

Might one approach mentioned there would work well for you.

Please tell me if you get the solution.

@HamzaHajeir ArduinoOTA relies on MDNS, and MDNS was sort of broken before. Try with beta2. Also, your laptop firewall must allow the traffic, try disabling it for testing.

I've reached a point all firewalls are enabled xD

But for me all firewall settings are ok, Because i can upload binary file OTA but by a command via Command Prompt.
