Connection happens without entering static passkey too

[Newbie]

Hello,

I am using sdk12.2.2 and nrf52 customized board. I want that user should be prompted to enter passkey before bonding. I refereed the code snippet from devzone and was able to implement static passkey but my challenge is that even without entering passkey I am able to access device.

I am attaching my main file for your reference.

Thanks,

main.c

Did you update attr_md for your characteristic to require MITM before allowing a peer to read/write to it. Tutorial here: https://devzone.nordicsemi.com/tutorials/b/bluetooth-low-energy/posts/ble-characteristics-a-beginners-tutorial
