iPhone X running Bluetooth 5 cannot pair with my Bluetooth low energy device

[Anonymous]

iPhone X running Bluetooth 5 cannot pair with my Bluetooth low energy device with the chip CYBLE-214009-00 running Bluetooth 4.1. Other iPhone models works fine.  I even upgraded to iOS 12 beta with no luck.

Here is the log:

CYBLE_EVT_GATTS_READ_CHAR_VAL_ACCESS_REQ: handle: 3

CYBLE_EVT_GAP_AUTH_FAILED, reason: AUTHENTICATION_TIMEOUT

CyBle_PulseCtrlSendNotification API Ok: 0

CyBle_PulseCtrlSendNotification API Ok: 0

CYBLE_EVT_GATT_DISCONNECT_IND

CYBLE_EVT_GAP_DEVICE_DISCONNECTED, reason: 13

Any clue will be much appreciated. Thanks in advance!

Hello,

Is it possible to share your design where we can replicate the issue?

Can you please update all components to latest versions in PSoC Creator and test the design at your end.

Thanks,
