Long Advertising Interval Causes GATT ERROR (0x85)

[Nguyen Tuan Anh]

Hi, I have trouble when working with my application bases on UART project on nRF51822 board. I use NRF Connect applicaton on my phone to connect with my board. Sometimes i try bonding and deleting serveral times. As soon as I do that, my board starts getting in trouble. I found that advertising interval time is too high (About 1500s) in compared with defined time in my code ( About 190ms). That causes my phone not to be able to reconnect to my board. I have tried to reset my chip but nothing changed until I flash the chip again.

Please help me to find out what causes this problem and how can I fix it. Here is some pics of my problem

.

Many thanks.

Hi,

Which phone and OS are you testing this with? Have you tried with different phones?

Thank you for your help. I have fixed this problem by myself. It is about PM_EVT_PEER_DATA_UPDATE_FAILED event. It only happens in some sort of phone branchs like huawei and xiaomi.
