GATT error problem in nRF51822

[sunil kumar]

Hello iam using softdevice 110 and SDK 10.0.0, I have created project using ble_app_uart example code, i have added device manager APIs to manage bonding. Problem is iam GATT error 0x85 and 0x8 randomly on my android phone(versions:-android 6.0.1, android 4.4.2, android 7.0) which is bonded, GATT error 0x85 is causing loss of bonding in android due to which i have to pair again, is there any way to come out of this. I have attached snipper trace nrf51822 sniffer trace.txt and screen shot Screenshot_2017-06-16-11-18-30.jpg of nRF toolbox app, kindly help me ASAP.

There are many questions regarding 0x85 and 0x8 in here. Have you searched and see if any of those can solve your problem? You have not attached a sniffer trace, you have attached a printf log from the chip. A sniffer trace shows the Bluetooth transactions on air.

It is difficult to say what could be causing this, I don't really know what you have done in your code. Maybe you can upload your complete project so I can test it here.
