Hi
AfterI updated the nrf_Connect v2.02 IOS version. I found that disconnect will happen when key in the bonding code "123456".
And my code never has this issus with previous app version ( I forgot which version number, but the APP interface is totall difference with this v2.02)
I also tried my code with Android nrf_Conect v4.23, it works fine when bonding, no disconnect happend.
I would like to know is't a APP issue or my code's problem. Thanks.
my cellphone is iPhone 6S, ios version is 12.4.1
attaced is my main.c file. it;s modified from ble_uart sample code.
