Advertising Failure After Multiple Pairing Requests and Cancels

[S0UL4]

Hello everyone,

I'm using the Bluetooth Peripheral sample UART and have noticed an issue.

When I perform a lot of sequential pairing requests followed by cancels from my phone quickly ( like DDOSing ) to my device, after around 4 or 5 requests/cancels, it stops advertising.

Is this normal behavior?

How can I handle it?

err = bt_le_adv_start(BT_LE_ADV_CONN, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));

Even with re-calling this function in Disconnected callback, it gives no error :( but the device is not showing in the bluetooth on my phone

I would really appreciate your help in this matter!

Thanks in advance.

Iheb
