Connect/disconnet issue

[abe]

Hi, I'm developing new project, and during test I see that, if you quicly connect/disconnect/connect.... and so on, the app seems locked...
Tu exclude my HW-FW, I tried same test using PCA10056, Nordic_Blinky sample from nRF5_SDK_16.0.0_98a08e2.
I have same result: if you try to repeat connect/disconnect/connect ... and so on , the module stops and it need to restart to make it working.
To best understand, here attached a video that shows the issue.
What's wrong? Where I mistake?
Best regards

Hello, Abe!

I tried to reproduce the error using the same configuration as you, but did not manage it. Could you please reveal what phone and Android version you are using?
In addition, could you try to induce the error and then see if its possible to connect with another phone (just in case, too see if it could be an error with the application),

Best regards,

Carl Richard

Hi Carl, I tried many times using HUAWEI P20 Pro phone with Android 9, but I tried some times also with other phone such as Motorola, Oppo, Samsung...
Please, take note that you must very quickly connect/disconnect/connect... leave a little pause then quickly connect/disconnect/connect...after few pauses the issue occurs

When error occurs, the device in not discoverable even for other phones

I see. I tried to do it as you described, but the error did not occur. Could you also say which DK version you use, as well as the nRF Connect app version (though I assume you use the most recent one)? This way I can be able to reproduce the configuration as accurately as possible. 

Regards,
Carl Richard

nRF Connect is version 4.22.3

The newest version is of the nRF Connect Android app is 4.24.2. Could you try to update, if possible?

And could you give me the hardware version of your PCA10056 development kit? It is located on a white sticker on the board. (see picture)

This my DK

Thank you. I will try again now. 

In the meantime, do you have the opportunity to provide a log of the operation? Just use a serial terminal like termite or the likes of it.

Best regards,
Carl Richard
