Hello,

I tested this sample with the nRF52DK, and it is working fine on my end. Before making a connection, it should ask for a passkey. After entering the passkey (which will be visible from the UART terminal), it will establish a connection. I think this security feature has failed on your side. Have you changed anything inside the sample? See my screenshots below:

i trace source-code, then add option CONFIG_BT_KEYS_OVERWRITE_OLDEST=y. 

the PC connect this hids-example OK.

but myself project also error, , in PC, after enter the correct PIN,  the dialog display status switched between <paired> and <connected>

Hello,

Sorry, I didn't quite understand your explanation. Are you saying that including CONFIG_BT_KEYS_OVERWRITE_OLDEST in your application causes it to crash or disconnect? Or are you having trouble running the sample from the SDK? I apologize for the confusion, but I couldn't fully grasp the issue from your description.

Kind Regards,

CONFIG_BT_KEYS_OVERWRITE_OLDEST=y only solved the question PC cannot connect the board.

Hello,

Do you mean that CONFIGS_BT_KEYS_OVERWRITE_OLDEST helped resolve your issue? Sorry, but I am having trouble following what you have written, possibly because of the translator you are using. Never mind if the issue is solved, but if you are still struggling, explaining a bit more will help me look into this.

Kind Regards,
