The ProCamera not take picture?

[TIMAI2]

What have you debugged ?

Suggest you set a notifier here to check that the message has reached and started the clock timer.

You should also check that that the procam is initialised

You also appear to be setting a procam output to a diferent location for the "second" and subsequent images ?

First, rework your Screen.Initialize blocks, especially the arbitrary (pointless) request for permissions (which, moreover, no longer exists for WRITE since Android 11).

The process of requesting Bluetooth permissions has been explained many times here in the forum, not least by me.

Thanks.
actually, I made it like this, still:

1. camera doesn't come out;
2. not take pictue;
3. i set the camera come out when APP run, failed why?
4. add some noties in Screein1.PermissionGranted, didn't see pop out:

[lladam]

Thanks.
I rewrite the screen,Initialize no much changes.

1. the BLE works well, added notifier in 'TAKE_PICTURE' got pop;
2. seems other permissions did granted?
3. come up allow ... access photos: DENY ALLOW need select, why not just grante the permission?

@lladam

permission?

See here:

StorageAccess Extension: Simplifying Storage Permissions in MIT App Inventor

It is unnecessary to request READ and WRITE permissions together on Android < 11, because WRITE permission always implicitly grants READ permission. Automatically (extension-controlled) requesting storage permissions is generally not a good idea. If only READ permission is required, only that should be requested. On Android >= 11, it should of course also be possible to request READ permission (Android 11-12: READ_EXTERNAL_STORAGE and Android >= 13: READ_MEDIA_IMAGES (_AUDIO, _VIDEO). O…

Do not ask for all permissions at the same time!
See here about how to ask correctly for Bluetooth permissions

Bluetooth liste of devices deosn't work anymore

To check it out, here are two AIAs. BTclient_test1.aia (7.5 KB) BTclient_test2.aia (7.5 KB) BTclient_test1.aia uses your blocks and doesn't work. BTclient_test2.aia uses my blocks as I always posted them. This works. So build the APKs and check it on Android 12+... And this version works with Companion & APK: [grafik] The extension GetASD can be found here

And move the lower part for example into a button click event

For Procam functionality, make a separate, simple as possible example aia project. does that take a picture ?

[lladam]

thanks.
I'll test that.

the global.device is for ESP32 BLE connection, I try to use ESP32 BLE to control the ProCamera to take picture not success.

[lladam]

thanks.
that code was working well to take picture and save it.

1. I made changes try to use only one button and moved ProCamera ini into screen1.ini, it works for the APP first time run, the camera doesn't come up when APP restart.

2. problem here is about try to use ESP32 BLE control the ProCamera to take picture, I added the well run ESP32 BLE blocks onto it, it doesn't take picture now.

If you are getting plain black images taken, you may need to set a timer to give everything time to setup.

I did a small test, using firebaseDataChanged with a node value of true/false - if true take a picture.

I left this value set to true, and refresh the companion, and got a black picture. Adding a clock with a time interval of 3 seconds, on refresh it took a picture

[lladam]

Thanks.
I am trying to test it, where did you get: call.File1.MakeFullPath?

[Taifun]

@lladam

File1.MakeFullPath

Try the file component
Taifun

[lladam]

great.
Thanks.

[lladam]

Sorry.
where can find : firebase db?

[TIMAI2]

Experimental

but why not try a timer with your existing code and the ESP32 ?

[lladam]

Thanks.

I tried to use clock like this, just can't make it work. this one crashed, why?

[TIMAI2]

You need to ask for camera permission before you try to initialise procam.
You should initialise procam before you start the clock, which is to take the picture.

[lladam]

Thanks.
I made the blocks borrow you picture and added 3000, got white screen at first start, and black screen at restart.
how to fix?
any where have a example that MIT APP received ESP32 siginal to take picture?

[TIMAI2]

If this is with a compiled app, then you might need to restart because I was lazy with the permissions request.

Is your firebase setup correctly to return true or false for a tag called take ?

Sorry, can't help with ESP32.

[lladam]

Thanks for all helps.

1. still from the #1 block, I did many test find out a strange phenomenon: the APP works manually by button; the BLE connection is good; just do one thing, let the BLE trig either of ProCamera or ProCamBase64 initialize after connected, can not do it.

I wonder if there is confliction of BLE with them? why the camera can be ini only by button?

2. added ProCamBase64.Initialize after BLE received 'TAKE_PICTURE'; manually button still works ini cam and take picture, click BLE trig nothing up, and crashed.

thanks for more attention.
