does SDK9.0.0 support BLE_GAP_IO_CAPS_DISPLAY_YESNO mode when bond?

[fuzhongping]

i used SDK9.0.0 to implement the function that bond to cellphone.

case 1:when i set the IO_CAPABILITIES to BLE_GAP_IO_CAPS_DISPLAY_ONLY,the process of bond is ble device show the PIN and need to input PIN in cellphone.

case 2:when i set the IO_CAPABILITIES to BLE_GAP_IO_CAPS_DISPLAY_YESNO, the process i was desired is ble device and cellphone show the same PIN,ble device use botton to confirm the bond.but the actual situation is same as  case 1.

how can i implement case 2?

thanks.

I believe BLE_GAP_IO_CAPS_DISPLAY_YESNO is only used for LE Secure connections:

This is not supported in SDKv9.
