Hi Łukasz,
Thanks for looking into this.
However in logs I cannot see SMP Pairing Response, but I should see it if

Hi Amr,
yes this is the Android side issue. Actually when you look at btsnoop you
can see Pairing Request showing OOB flag is 0.
SMP: Pairing Request (0x01) len 6
IO capability: KeyboardDisplay (0x04)
OOB data: Authentication data not present (0x00)
Authentication
After some further research and debugging, I believe I've been chasing a
red herring.
Debugging the mynewt device during the pairing process shows that the
requester (Android phone) does not have its OOB bit set (this can be seen
in ble_sm_lgcy_io_action). This explains why OOB was failing. It
Hi Łukasz,
I've sent you the Android Bluetooth HCI log separately to your email.
The log was saved while the following events took place:
- With my device in idle mode, I used my phone to read the device's NFC
tag. I configured the NFC tag to represent a Bluetooth Carrier
Hi Amr,
I would call it on gap connected event. Then OOB data are stored and SM can
present/use OOB flag during pairing.

Hi Łukasz,
Thanks for your reply. Where and when should the call to ble_sm_inject_io
take place? In my current setup, I had configured my device to use passkey
pairing, but for testing purposes, was hardcoding the passkey. The BLE
stack was requesting the passkey by calling the GAP event
Hi Amr,
Nimble does support OOB for Legacy and Secure Connections Pairing.
In both cases you just need to provide OOB (TK) data exchanged by other
means e.g. NFC to the NimBLE stack using "int ble_sm_inject_io(uint16_t
conn_handle, struct ble_sm_io *pkey)".
For Secure Connection make sure to
Hello all,
I'm interested in using OOB pairing over NFC to connect my peripheral
device to a master (an Android phone in this case). The NFC Forum has a
specification (
https://nfc-forum.org/our-work/specifications-and-application-documents/application-documents/)
which dictates how two
