Hi,

From what I can see this must be logged in the handling of MTU update when CONFIG_BT_GATT_AUTO_UPDATE_MTU=y. 0xE is BT_HCI_ERR_INSUFFICIENT_SECURITY. I am not sure why you got this, though. Do you see anything from debugging (particularily the handling of MTU in gatt.c)?

Are you able to reproduce it with samples on a DK?
