Hello
I tried to set the mail.properties in my rpi in the web page:
https://192.168.1.245:xxxx/admin#/users/edit/xxxxxxx@xxxxx.fr-Blynk
https://gyazo.com/afebebc4e5aa65a18244a80d917d81de
When I click on save, the page tells me it’s save.
But when I refreshed the page, the configuration was not taken into account, I try by relaunching the rpi and it’s the same
An idea ?
thx
I guess, by design, the V Save Changes confirmation is just in memory, for the current running Blynk Server process. Normally we use that feature to test, before finally implementing, after thorough testing / finding out the modification is OK.
I still think that designing this way is much better and smarter than forcing you to change the real config files, rebooting the Blynk Server, just to test, then finding out not OK, and repeating the process until everything is OK.
Whenever you’re satisfied with the results, you can edit the real config files (in your case mail.properties) to make the change permanent. Certainly you have to reboot the Blynk Server to make the change effective.
Hello
Thx khoih for your answer
Ok, I went to see ssh, but I can not find the file “mail.properties”.
Where is it in the rpi?
@ +
After you use SSH to log into RPi, for example if your Local Server Local IP Address is 192.168.2.112, you use this command from a computer terminal
$ ssh pi@192.168.2.112
pi@192.168.2.112's password:
Linux raspberrypi-02 4.19.75-v7+ #1270 SMP Tue Sep 24 18:45:11 BST 2019 armv7l
....
pi@raspberrypi-02:~ $ find . -name mail.properties -print
./Blynk-Server/mail.properties <======= This is where the file is
# Comment. Use this command to edit file mail.properties
pi@raspberrypi-02:~ $ gedit ./Blynk-Server/mail.properties
Normally, the file is at :
~/Blynk or ~/Blynk-Server, depending on where you installed the Blynk Server.
Thx for the answer.
when I search the file as requested
it does not return anything to me:
pi@ServeurBlynk:~ $ ls
Blynk Desktop Documents Images logs MagPi Modèles Musique Public server-0.41.11-java8.jar static Téléchargements Vidéos
pi@ServeurBlynk:~ $ find . -name mail.properties -print
pi@ServeurBlynk:~ $So you installed Blynk Server jar without several necessary files, such as mail.properties, server.properties, etc.
You have to create / copy / modify and place them in your Blynk subdirectory
mail.properties fromserver.properties fromI notice that you put the jar file server-0.41.11-java8.jar not in Blynk subdirectory. It’s better to move it into Blynk subdir. , together with those properties files, and remember to change the command to start the server correspondingly.
Thx for the answer.
I made the changes as requested
I created the 2 files in the folder. \ Blynk
pi@ServeurBlynk:~ $ ls
Blynk Images Modèles server-0.41.11-java8.jar Vidéos

Is it normal for files to change ssh to not show up with registered items?

I am not the best in terminal unix

I’m sorry I don’t fully understand what you mean here

You can use French with or without English as I can understand.
I still don’t know why you don’t find logs subdirectory. Possibly because of permission. Can you try to use sudo, ls -la and find, such as
pi@ServeurBlynk:~ $ sudo ls -la
pi@ServeurBlynk:~ $ sudo find ~ -name logs -print
/home/pi/ServeurBlynk/logs
pi@ServeurBlynk:~ $ sudo ls -la /home/pi/ServeurBlynk/logs

Bonjour 
Merci, j’ai trouvé les logs grâce à votre réponse.
dans : /home/pi/logs/blynk.log
je vais éditer le server.properties et le mail.properties correctement
Is it normal for files to change ssh to not show up with registered items?
est que c'est normal que les fichiers chnager en ssh ne sont pas rafraîchit/afficher dans la page web de configuration de Blynk.
Du coup ça répond sans doute à la phrase que vous n’aviez pas compris, Blynk ne charge pas ces 2 fichiers car ils sont mal éditer et donc ce sur la page web sont ce de base de Blynk. c’est ça ?

Donc je n’ai pas de log de Blynk.
Par contre je pense qu’il tourne comme un “service” ? non ?

Edited
Just added some notes for other people knowing what’s going on here,
so I edit the files as indicated in the blynk docs but nothing seems to be taken into accountI suggest that you put the Blynk Local Server jar file in the same directory /home/pi/Blynk as all other *.properties files.
Currently, your jar file is at /home/pi, and your *.properties, dataFolder are all in /home/pi/Blynk from your command to start Blynk server:
java -jar /home/pi/server-0.41.11-java8.jar -dataFolder /home/pi/Blynk
It’s better you start over from reading README.md in
For example:
Create file mail.properties within same folder where server.jar is
in
Enabling mail on Local server
To enable mail notifications on Local server you need to provide your own mail credentials. Create file mail.properties within same folder where server.jar is. Mail properties:
mail.smtp.auth=true
mail.smtp.starttls.enable=true
mail.smtp.host=smtp.gmail.com
mail.smtp.port=587
mail.smtp.username=YOUR_EMAIL_HERE
mail.smtp.password=YOUR_EMAIL_PASS_HERE
You can also move all *.properties files out to /home/pi, but this is not a clean solution.
I’m afraid you have some confusion because the mistake in the above-mentioned README.md, such as
java -jar /home/pi/server-0.41.12-java8.jar -dataFolder /home/pi/Blynk &
in this paragraph suggesting you placing the jar file in home/pi, not in home/pi/Blynk
Enabling server auto restart on unix-like systems
To enable server auto restart find /etc/rc.local file and add:
java -jar /home/pi/server-0.41.12-java8.jar -dataFolder /home/pi/Blynk &
If you move the jar file to /home/pi/Blynk, remember to change the command to
java -jar /home/pi/Blynk/server-0.41.11-java8.jar -dataFolder /home/pi/Blynk &

is it normal for files to change using SSH (Secure Shell) are not refreshed / displayed in the Blynk Server configuration web page.
That was answered in 1. because Blynk jar expects the *.properties files are in the same folder. Otherwise, it just uses the default version of *.properties files in memory, and pretending to save (actually saving to its Memory) and displaying V Save Changes. Certainly it’s not saving to not-found physical files.
If use use SSH to log and edit the files located in correct folder, everything will be refreshed / displayed / used after you restart the Blynk Server (kill-restart-jar, or reboot, etc.
archive subfolder, where the file name is something like blynk.log.2019-12-05, and you can specify the level of logging to avoid using too much space by specifying which one you pick#log debug level. trace|debug|info|error. Defines how precise logging will be.
log.level=error
#log.level=info
Bonjour
Merci pour toutes ces informations !
J’ai déplacer le fichier server-0.41.11-java8.jar dans le dossier /home/pi/Blynk
j’ai également édité le crontab -e pour que blynk démarre à chaque reboot
Le fichier mail.properties est bien pris en compte maintenant
mail.smtp.auth=true
mail.smtp.starttls.enable=true
mail.smtp.host=smtp.gmail.com
mail.smtp.port=587
mail.smtp.username=xxxxxxxxxxxxxx@gmail.com
mail.smtp.password=xxxxxxxxxxxxxx
mail.smtp.connectiontimeout=30000
mail.smtp.timeout=120000
Mais Google ne semble pas vouloir utilisé cette appareil, j’ai eu ce mail de la part de google a l’envoi de DATA en csv depuis le téléphone portable ( signe que tout a été pris en compte ):
L'accès à votre compte par une application suspecte a été bloqué

Google a empêché quelqu'un de se connecter à votre compte à l'aide d'une application n'appartenant pas à Google. Si ce n'était pas vous, cela signifie que quelqu'un d'autre connaît votre mot de passe. Nous vous conseillons donc de le modifier immédiatement.

J’ai indiquer que c’était bien moi en cliquant sur oui c'est bien moi mais il ne semble ne pas être d’accord :
Application moins sécurisée bloquée
Google a bloqué l'application que vous essayiez d'utiliser, car cette dernière ne respecte pas nos normes de sécurité.
Certaines applications et certains appareils utilisent une technologie de connexion moins sécurisée, ce qui rend votre compte plus vulnérable. Vous pouvez désactiver l'accès pour ces applications (recommandé) ou l'activer si vous voulez les utiliser malgré les risques encourus. Google désactive automatiquement ce paramètre s'il n'est pas utilisé.
j’ai modifier le port mail.smtp.port=587 en 465 mais idem…
Une idée ?
Re
Je répond a moi même…
Il faut autorisé l’accès aux applications moins sécurisé dans les parametre de sécurité de Google
et zouuu

That’s good you found out and everything is OK now, I think.
The solution is to sign in using an App password
An App Password is a 16-digit passcode that gives a non-Google app or device permission to access your Google Account. App Passwords can only be used with accounts that have 2-Step Verification turned on.
