Intermitent issue when try to provisioning device about esp-idf-provisioning-android

[KhushbuShah25]

Hi @jlpuma24 , Can you give some more details like which idf version and Android version you are using ?

[jlpuma24]

Thanks for answer @khushbushah2302 i'm using the latest one 2.1.1, and the android version what i'm using are 12 and 13.
Thanks!

Hi @jlpuma24 , can you please install esp-idf v5.0 device firmware and check this ?

Hi @khushbushah2302, i am the firmware engineer on the project with @jlpuma24 that has this issue. I have updated to esp-idf v5.0 and i am running the wifi_prov_mgr example without changes to replicate the issue we are seeing. The issue is still there with the latest esp-idf. i have the example configured to reset provisioning after a esp32 reset (CONFIG_EXAMPLE_RESET_PROVISIONED).

when using the ESP BLE Prov app (App version – v2.1.0 – 7f8108a) i see the issue that we believe to be the same as what happens on our custom app. after a successful bluetooth connection and provision, i click "provision another device". i reset the esp32 and then select it from the device list on the app. it then immediately shows "device disconnected". the message disappears after a few seconds. I can also close the app immediately after a successful bluetooth connection without completing the provisioning, reset esp32, then open app again, and the "device disconnected" message will appear after selecting device.

here is the esp32 device log on a BT failure:

Hi @jlpuma24 ,
We have fixed the issue in app and firmware (esp-idf v5.0). But app is still in beta stage. Can you install ESP BLE Prov beta app (version - v2.1.2 - 661f84d) and check this ?

[jlpuma24]

Hi @khushbushah2302 i didn't see that commit, or branch, or tag in the tree. Can you clarify how can i got the access to this version? Thanks!

[KhushbuShah25]

Hi @jlpuma24 ,
The app side commit is not available on GitHub yet. It will be available soon.
For installing beta version of app, you need to join the beta program from PlayStore as shown in screenshot. You can install beta app by updating current app after sometime of joining beta.

[KhushbuShah25]

Hi @jlpuma24 , app is released now. Please check with new app.

[adamlehotay]

Hi @khushbushah2302, I have tested the new app and it still shows the "device disconnected" message every other provisioning attempt. For the custom android app that @jlpuma24 is developing, which also has this problem, we have found that the issue is only happening on samsung devices.

[cliut]

@adamlehotay I have same issue with samsung devices. did you resolve this issue?
