Announcing IoT push notifications

[kl3m3n]

@sato try with version 1.0.4. Do you still experience problems?

You should also disable all battery and related optimizations for the GUI-O app or the OS will kill the service...

@sato can you please send me the Android version (not GUI-O version)?

[Sato]

@kl3m3n,

Now, with your example code, the Samsung Galaxy A30s works the Push notifications, on that is Android10

On my other Samsung Galaxy M22, the notifications no work more with the same example code "changed obvious the Application UUID", this phone have Android11

@sato Hello, I see the crash reports from the M22... I am making a call on null value (although Android API says the value I am calling cannot be null in this case). I will add a null check and upload the app to beta testers (I believe you are a beta tester? You can check this on Google Play Store, GUI-O listing...).

@kl3m3n

Please explain how can i get the Beta, sorry, it's new for me

Hi @kl3m3n,

The current situation!

I added in your example code the sending of notifications automatically every 60 seconds via the milis function

The cell phone with Android10 gets the notifications with the App closed, but if I try to open GUI-O, it freezes with a black screen

The cell phone with Android11 gets the notifications only if the App is open, i.e. it doesn't need to is connected, it only needs to be with the GUI-O logo Connect . Create . Control, but when it receives the Notification this does not overlap the image that is on the screen, I do not know if it is so and I can not compare with what Androi10 has because it does not open the Gui-O

Hope this helps

Regards

@sato hello, thank you for the update... I am reading that Samsung is killing services like crazy (especially newer devices).
They have very aggressive battery optimization techniques that break the concept of foreground services. Please see:
https://dontkillmyapp.com/samsung
Try following the instructions to (at least) paritially fix this. Please keep me informed.

I have an older Samsung phone (Android 7) and newer Xiaomi phone (Android 11) and I do not experience the issues that you have.

I will also try to find a solution for this.

@kl3m3n,

Ok, Thank You

When you have some global solution, that is, independent of the manufacturer of the cell phone would be ideal.
It is complicated that to use this great GUI-O functionality you have to use some specific equipment.

When have news, please informe us.

Hi @kl3m3n,

Sorry, i again with questions.

I can send message from ESP32 to Whatsapp or Signal trough a Bot, on my both Samsung Mobiles, this Apps works with background service too, or it's diferent?

Another questions is, how can get this Text "OF4321" like the attached Scrennshot, to a String variable

@sato
I have been running the push notification service for approx. 10h (Android 7, Samsung Galaxy S6), without any problems sending the notification every 30 seconds. Everything still works ok. So, I am convinced that the service works ok. I will try it on my Xiaomi device also (Android 11) for prolonged duration, but I also don't see any problems here...

Regarding Whatsapp - OEMs (e.g., Samsung) probably keep some list of whitelisted applications that the OS is not allowed to kill, so there is definitely some difference here.

This is (in my opininon) one of the few drawbacks of Android systems (comapring to Apple devices) - due to open sourceness, the OEMs can do what they want, often breaking some core functionalities.

Regarding your second question - when creating a device, specify the optional user name. This is then sent in the usr: parameter. So:
Quick pair -> IoT devices -> add a new device -> specify device and user name.

Hi @kl3m3n,

I will try to explain
When I supply the pcb with ESP, I create a device on my phone, with for example, New_987 and no username, from there, I have the In and Out topics that i put in the code to compile in the ESP, the client can later change this name New_987 and it continues working.
Now, if I also use the username and the client makes changes, it stops working.
That is why I ask how to read this device name that appears in the sub-menu of Quick connect, to a String variable, as I sent in the post with the screenshot, so I don't need the username. Please test what I am mentioning.

Regards

[kl3m3n]

@sato Why don't you specify the user name also? You will then be able to filter incoming messages based on user name also (not just device name, which can be the same on different Android devices).

Hi Kl3m3n,

Since 10 hours ago I have re-enabled Push Notifications every 5 minutes. I disabled all possible battery management. It now works with my Samsung Android 11. Sometimes after receiving a Push Notification the GUI-O freezes, can't open, shows Gui-o black screen. Then I go to settings - Apps - choose GUI-O and confirm the "Force to close". After that, it works again and I don't need to restart the phone.
Another question, how many notifications can it show. Currently, when you get a new Notification, always delete the last one.

I know I ask a lot of questions, sorry
Best regards

Hi kl3m3n,

My Sansung M22 updated the firmware to Android 12
Gui-O is still working, but Push notifications are not.
All the settings remained the same, that is, Android12 did not
changed anything, all the battery management options and others remain as they were before the update.
There is a warning about Gui-O where it says that the developer of the App should make corrections so that it works with this new version.
Attached I send the alert image.
