ESP12 not working with Arduino IDE

frank75 · October 16, 2018, 8:36am

Hi,

I am a beginner in using the ESP12 board with Arduino IDE,

After learning from Installation · ESP8266 Arduino Core

as per their suggestion in Arduino IDE -> File-> Preferences-> Additional Boards manager URL -> added URL :http://arduino.esp8266.com/stable/package_esp8266com_index.json ->pressed ok

After this in

Tools-> Board: "Arduino","Genuino"->Board manager->searching ESP8266

But after searching nothing appears on board manager search, I have attached the snapshot also,

Please suggest avoiding this kind of issue. Looking forward to your advice

After you close Boards Manager, you'll see a bunch of text in the black console window at the bottom of the Arduino IDE window. Please copy all off that text (you may need to scroll the window up to see it all) and then paste it in a reply here using code tags (</> button on the toolbar).

I have installed a fresh copy of the IDE but continue to get this error when ope…ning the Boards Manager. I have followed instructions on the forum to rectify the problem but nothing works. I am running Windows 10. I can access this URL from my browser. I am able to install some of the boards that are listed in the Boards Manager, but most give errors when trying to install. ![image](https://cloud.githubusercontent.com/assets/16300778/17276253/942285a2-5723-11e6-80f3-965c1f42e815.png) ```text Error downloading http://downloads.arduino.cc/packages/package_index.json java.lang.RuntimeException: java.lang.Exception: Error downloading http://downloads.arduino.cc/packages/package_index.json at cc.arduino.contributions.packages.ui.ContributionManagerUI.lambda$onUpdatePressed$0(ContributionManagerUI.java:151) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.Exception: Error downloading http://downloads.arduino.cc/packages/package_index.json at cc.arduino.contributions.DownloadableContributionsDownloader.download(DownloadableContributionsDownloader.java:113) at cc.arduino.contributions.packages.ContributionInstaller.download(ContributionInstaller.java:330) at cc.arduino.contributions.packages.ContributionInstaller.downloadIndexAndSignature(ContributionInstaller.java:305) at cc.arduino.contributions.packages.ContributionInstaller.updateIndex(ContributionInstaller.java:283) at cc.arduino.contributions.packages.ui.ContributionManagerUI.lambda$onUpdatePressed$0(ContributionManagerUI.java:147) ... 1 more Caused by: java.net.SocketException: Address family not supported by protocol family: connect at java.net.DualStackPlainSocketImpl.connect0(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:83) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at sun.net.NetworkClient.doConnect(NetworkClient.java:175) at sun.net.www.http.HttpClient.openServer(HttpClient.java:432) at sun.net.www.http.HttpClient.openServer(HttpClient.java:527) at sun.net.www.http.HttpClient.<init>(HttpClient.java:211) at sun.net.www.http.HttpClient.New(HttpClient.java:308) at sun.net.www.http.HttpClient.New(HttpClient.java:326) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(HttpURLConnection.java:1169) at sun.net.www.protocol.http.HttpURLConnection.plainConnect0(HttpURLConnection.java:1148) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:999) at sun.net.www.protocol.http.HttpURLConnection.connect(HttpURLConnection.java:933) at cc.arduino.utils.network.FileDownloader.downloadFile(FileDownloader.java:170) at cc.arduino.utils.network.FileDownloader.download(FileDownloader.java:128) at cc.arduino.contributions.DownloadableContributionsDownloader.download(DownloadableContributionsDownloader.java:111) ... 5 more ```

It has been reported to be caused by having spyware running on your computer.

@OP

Please, post the pictorial view (or link) of your ESP12 Board. There are many varieties of boards; but, all are generally called ESP8266 Boards. Mine one is NodeMCU1.0-12E Module. It is working fine with Arduino IDE.

pert · October 16, 2018, 10:40am

This issue has absolutely nothing to do with the ESP12 board. It's a problem with downloading the Boards Manager JSON file. The same error would occur even if frank75 hadn't added the ESP8266 Additional Boards Manager URL because it's not even getting past the download of the official Arduino JSON file that is done before downloading the 3rd party JSON files.

frank75 · October 16, 2018, 1:41pm

Hi, Yes by using these different ways I am able to install the ESP8266 board in Arduino code by

-open the preferences menu,

Navigate to the "More preferences can navigate directly" .Arduino15 folder clicking on the preferences path.
open the folder staging/packages and try to delete all the archive you have there.

If Still won't work then

-Open cmd prompt.

type "setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true"
Click enter

If Still Issue occurs then:

search for "Network proxy settings"
turn off the automatic proxy setup

Note: after every step mentioned above do Restart Arduino IDE again.

Thanks a lot for everyone help

I'm glad to hear you got it installed. Enjoy!
