SEC_GATTC_DEMO: pair status = fail ; SEC_GATTC_DEMO: fail reason = 0x63

Hi i am modifying the [esp-idf/examples/bluetooth/bluedriod/ble/gatt_security_client]
after entered the correct matching password, the connection is failed
below is the log. it is showing the pairing failed.

But once i perform reset to the esp32, the esp32 can pair successfully.

i try to look the error message and also the fail reason from the coding. but i could not locate the what is mean by the reason 0x63.

Code: Select all

[0;32mI (2891833) SEC_GATTC_DEMO: fail reason = 0x63

Is there any description or document about this fail reason mean ? so that i can know what caused this error and can try to fix it.

Hi there, is there any update on BLE pairing fail reason document. It is not clear what these reasons are
thank you

I think I have found some clue here

Sorry for reopening, but, what does fail reason 0x63 means?

Thanks
