BLE_ERROR_GATTS_SYS_ATTR_MISSING

[VadimSavchuk]

Hi. I have a problem with HID keyboard example. Function sd_ble_gatts_hvx returns 0x00003401. I know that it's means BLE_ERROR_GATTS_SYS_ATTR_MISSING. But how and where I must set attributes or enable notification. I know that I must restore attributes from storage. But how? I read many posts about this but I can not to fix this problem. Please help me. Thank you in advance.

BLE_ERROR_GATTS_SYS_ATTR_MISSING does not handle

If you get no service discovery then the BLE_GATTS_EVT_SYS_ATTR_MISSING won't come.

You can try to call sd_ble_gatts_sys_attr_set(NULL) when you receive _CONNECTED event.

If you test with our ble_app_hid_keyboard do you see the same problem ?

SDK 12.2.0 .. If I use peer manager: -peer manager event do not come On Raspberry PI connected is stable, but sd_ble_gatts_hvx returns 0x00003401 Android and WIndows do not connect with pin code error If I use unmodified ble_app_hid_keyboard firstly all works fine and after reconnect I can not connect. If I restart NRF51 I can connect but sd_ble_gatts_hvx returns 0x00003401. If I unbound and bound again all repeats
