[BLE] pairing random value is incorrect

[mmt-10]

Hi,

I use STM32BW55.

I get trouble for pairing random value.

pairing random value is 0xffffffffffffffffffffffffffffffff.

How do I resolve it?

I set :

• static random address
• IR
• ER
• appearance
• IO capability : No Input/No output
• Bonding Mode : Bonding Mode
• Secure Connection : Not support

I attached WireShark's log.

I'm sorry for delaying update.

I resolved it.

I set wrong setting for RNG on CubeMX.

I fix setting for RNG, then pairing random value is random number.
