The uuid values of the two nRF52s I used are the same. Could it be related to this? I am not very familiar with the ble protocol.

I still cannot reproduce the issue with my phone and the Heart Rate Application which has LESC pair.

What os is the phone, Android or iOS? Did you try other phones? Could you test with the Heart Rate Application?

actually the problem is independent of nRF52. I did not experiment with sdk samples. However, when I connect to one of 2 different nRF52s with the same software, sometimes it connects to the other at the same time. this has nothing to do with the nRF connect application. The same problem occurs when I pairing via the bluetooth menu of my mobile device. When I pair with one of 2 separate nRF52 devices, it can connect to the other. Although not always, it happens once in an average of 5 attempts.

Hi,

I cannot reproduce the issue with ble_app_template on nRF52832 DK.

What is your application? What SDK are you useing? Do you also see the issue with the SDK examples?

Has anyone ever had the same problem as me?

How are you making that choice?

this situation leads to:
For example, there are two separate devices containing nRF52 in the same environment. One is mine and the other is my friend's. When I connect to my device with the mobile application, I also connect to my friend's device at the same time. my friend's device is stopping advertising. For this reason, my friend cannot see his own device when entering the mobile application.
how can this situation be prevented?
