Hi @intent-kacper-cyranowski !

As you said to me, I have opened a new issue. I am attaching the logs you asked me in #1197 (comment)

EXPECTED BEHAVIOUR: the app connects to the device and ask for his state until the user closes the BLE connection manually

BAD BEHAVIOUR: the app connects to the device and ask for his state but connection drops

Hi @joanmarcs

We have opened a ticket for your issue. I would like to clarify some information.
Did the error occurred on different devices then previously specified? Samsung and Pixel have their own SoC, and if error occurs only there it might be the cause.
You have mentioned that you are working with vehicle chargers, can you specify what is the device, or can you provide any other device on which you were able to reproduce the issue.

Everything that will help in reproducing and solving the issue is welcome.

Hi @intent-kacper-cyranowski

We have only observed this in this brands as far as I know... I have a POCO that works fine, the same in QA team. A Nothing one also works fine. The vehicle chargers are using an ESP32.

Also observed with an ESP32 device.
Version 3.1.2

I get event disconnect after connect around 10-15 seconds, It's crazy,
The app try to connect again and again, it is the same

I can confirm this same issue, using PLX version 3.2.1, Google Pixel 9 connected to an ESP32 device, occurs exactly at 30 seconds.

+1 @nhaduongc same here. Every few seconds, Android drops connection, reconnects, then drops connection again.
