[@peterkent6399]

Great tutorial. One thing to note though is that if you have existing projects created on the Blynk cloud server you will have to modify the sketches to point to the local server. You will also have to clone the projects into the new local server account. At least, I couldn't figure out any other way to move them (other than starting from scratch).

[@SidsEClassroom]

Yes, I agree with you on that.

[@SidsEClassroom]

You can try and create a shared access link for the projects on the Blynk Cloud. May be that will save you the pain of starting again from scratch.

[@peterkent6399]

Hmm, thought about shared access but problem is that I think you can only share existing projects - which in my case were on the cloud server. Cloning is quick and easy but of course costs you "energy". Not a big deal unless you have multiple complex projects (which I did not). Thanks again for the tutorial.

[@macrokefag8406]

correct...... thank you very much

[@amernazirawan3908]

I have setup the local server as described in the video and very happy with the results, one thing i need assistance with that how to access my devices on this local server when I am outside or not on the same network through internet

[@SidsEClassroom]

You need to do something called port forwarding. There are many tutorials on the internet for that.

[@swannschilling474]

Hey Sid, since I found this very useful, you should probably state that the new android app has a different port setting...I know a lot of people will be very confused if their app will not connect to the local server! Or if you are having the time, you could probably do some tutorial on how to install the latest version of the Blynk Server? This video helped me so much on getting started with my local server...thanks a lot for the effort!! :)

[@aniketkapdule]

Swann Schilling i want help on this

[@swannschilling474]

Aniket Kapdule sure, where are you stuck...just check the Blynk Docs first! You just need to put the new port and everything will be working out!

[@aniketkapdule]

I checked it out and everything just work properly except the email services

[@swannschilling474]

Aniket Kapdule you need to create a mail.properties file in the same folder which holds your Blynk Server...there is a version that you can also download here below the clip! :)

[@aniketkapdule]

I've added that file still the auth token is not getting sent through email by the server

[@brice3011]

For openssl.exe to execute, in the command window, with the directory set at where the server executable is, the path to openssl.exe must be declared in the Environment Variables path settings.

I have a problem: the server is on, with the .bat file the server restart automatically and everything is allright (i can access to admin page etc), the sketch is working, but after a certain period of time the blynk app disconnects and says ''user is not registered'', what's the problem? My data are in a folder and i can see the backuo and deleted folder, the admin and the user txt file genereted

Hi Sid, first of all: thank you for your tutorial, it really helps! I am getting some trouble connecting the app to the server ( what you do okay at 18:50 ) , the app in the iPad says " sorry, server can't talk now, try later". The only thing that did not go like in your video before that was that the "server.properties" file did not say the same things as yours. Mine says : #provide either full path to files either use '.' for specifying current directory. For instance "./myfile.crt" server.ssl.cert= server.ssl.key= server.ssl.key.pass= While the one in your video ( 14:38 ) says : #provide either full path to files either use '.' for specifying current directory. For instance "./myfile.crt" server.host= server.ssl.cert=./server_embedded.crt server.ssl.key=./server_embedded.pem server.ssl.key.pass= is it normal ? do you think this is why the iPad cannot access the server ? Thanks a lot again !

[@SidsEClassroom]

I guess, you are trying to login into the local server with public server credentials. For local server, you need to create a new account. In the app, click on create new account, then click on the icon just above signup (3 dots and arrow), toggle the switch to custom and enter the server ip and port details and then click OK. Now enter your email and password details and click on signup. Now you should be able to login into the local server. Regarding the server.properties, i generated my own custom certificates and hence have those extra lines. If you have generated your own certificates as shown in video then you need to add those lines. Hope it helps.

Sid's E Classroom thanks please upload more project videos ...✌

[@dhirajmaan4768]

no, i am not

[@SidsEClassroom]

If you have tried everything what i suggested, post your issue in Blynk community forum.

[@Makarand_Ronghe]

sir will you please make the same video fro Rpi??

[@SidsEClassroom]

Unfortunatley, i don have a pi with me at the moment..

[@Makarand_Ronghe]

okay Sir

[@SidsEClassroom]

local server on rpi coming soon.. stay tuned..

[@Makarand_Ronghe]

Sid's E Classroom desperately waiting!!!

[@ضياء6]

it's so difficult!

[@kartiksingh9382]

please help me

[@SidsEClassroom]

Please visit the blynk website or their forums.. They have plenty of basic information that you are requesting.

[@thechariotvideos5654]

Can you please edit the video as at 7mins 50secs you show "/path" and this is an absolute no, no which will result in users loosing all their projects. Blynk guidance notes have been updated to reflect /path is not literal and for Windows users it means drive letter, folder, sub folder so something like C:/blynk/server/ with Unix (not Windows) forward slashes and certainly not /path. Same applies for Unix users, do not type /path but enter the pathway based on the your filesystem.

[@SidsEClassroom]

Thank you for intimating. An annotation has been added for the same.

[@SaurabhGangamwar]

your are right .if path is like this c:/users/username/Blynk server this will cause errors of adminstration

[@thechariotvideos5654]

It is much worse than that, people are actually typing "/path" which doesn't exist. This creates a tmp folder on the Windows machine and over time the tmp folder is likely to disappear along with all the Blynk projects created by the user.

[@thechariotvideos5654]

The annotation is incorrect, it isn't can it is MUST as there is no place called "/path" in Windows and the syntax of actual dataFolder is Unix style forward slashes not Windows backslashes.

[@SidsEClassroom]

Had overlooked. Changed now.

Hi, really nice video!! But I'm having troubles with openssl see... www.screencast.com/t/XlIllqzuDQ cmd says that don't recognise openssl as a command or instruction, but I've already instaled openssl 64bit (cause my computer is a 64 bits one) I'm pretty sure I'm missing something but dunno what. I'll be really thankful if you could help me. Please C:

[@SidsEClassroom]

+Jessica Piedras Hi, i had a look at the snapshot, unfortunately, i could not understand the language. If you could translate the error it will be helpful. And can you check as to whether the OPENSSL has been added to system variables. Kindly get back to me on teh same.

[@JanneRoe]

+Sid's E Classroom the error says: "openssl" doesn't recognice as a intern or extern command, software or executable file. I have openssl configuration in my system variables www.screencast.com/t/xI66DFP2w

[@SidsEClassroom]

+Jessica Piedras Ok, from the looks of it, i think you are running the command prompt normally, you need to run command prompt as administrator.

[@JanneRoe]

+Sid's E Classroom I've ran the prompt as administrator and is the same error message.

[@SidsEClassroom]

+Jessica Piedras Fine then, in system variables, you will find one parameter called path, edit the path and add the following C:\OpenSSL-Win64\bin now it should work

[@ahmeddesawi8189]

dear Mr. Sid's E Classroom good day to you! thanks for this awesome video but there are another response: --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- c:\Users\Ahmedmaarouf\Blynk Server>java -jar server-0.15.2.jar -datafolder /path Exception in thread "main" org.apache.commons.cli.UnrecognizedOptionException: U nrecognized option: -datafolder at org.apache.commons.cli.Parser.processOption(Parser.java:363) at org.apache.commons.cli.Parser.parse(Parser.java:199) at org.apache.commons.cli.Parser.parse(Parser.java:85) at cc.blynk.server.launcher.ArgumentsParser.parse(ArgumentsParser.java:4 3) at cc.blynk.server.launcher.ServerLauncher.main(ServerLauncher.java:49) c:\Users\Ahmedmaarouf\Blynk Server>openssl genrsa -out server_embedded.key 2048 'openssl' is not recognized as an internal or external command, operable program or batch file. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- waiting your reply for this problem please.

[@SidsEClassroom]

+ahmed desawi the "F" in "dataFolder" should be in capital. And regarding the openSSL, the openssl has not been added to the environmental variables.

[@ahmeddesawi8189]

sir, how are you today? thanks for your help. you are right about "F" and after I write this command in right way this message appears and there is nothing after that as pointer don't write any thing. ------------------------------------------------------------------------------------------------------------ Blynk Server successfully started. All server output is stored in folder 'c:\Users\Ahmedmaarouf\Blynk Server\.\logs ' file. ------------------------------------------------------------------------------------------------------------ openssl was added to environmental variables. so what else sir?

[@SidsEClassroom]

+ahmed desawi next step is to connect the blynk app to the local server.. all the steps are clearly specified in video.

[@ahmeddesawi8189]

s22.postimg.org/46vb0bwlt/Capture.jpg as you see in picture there is no pointer and the next step is paste first ssl cmd commands.

[@SidsEClassroom]

ahmed desawi Stop the server by pressing Ctrl+C and proceed with the SSL cmd commands

[@kakbro2730]

waste of time.
