Connect/disconnet issue

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

Carl, I'm sorry, but the file you sent does not have difference on serial output... I see same as previous sample...

Hello, again!

Sorry for the delayed reply. I have not managed to figure out this issue and will require some time to check internally with others. In the meantime you can try to induce the error again with the follwing .hex file. I've enabled more verbose logging on the BLE side.

blinky_with_dbg_v2.hex

Hi,
I sent you the capture log from serial channel.
With this code, when lock occurs, after HW reset of DK board reset the advertising starts but I'm not be able to re-connect the device.

Hi!

Could you do a nRF Sniffer trace of the connection, without resetting the board when it gets stuck? Hopefully we can find some anomalies there.

Installation and usage of the sniffer tool described here.

Kindly,
Carl Richard
