STM32WB55 as a central (client)
Sending ACI_GAP_SEND_PAIRING_REQ and getting ACI_GAP_PAIRING_COMPLETE_EVENT with failed. reason: AUTH_REQ_CANNOT_BE_MET.
As I matched all the other settings to the server(peripheral) device settings.
Was curious if the OOB feature might be failing it? How can I disable OOB ?
From your documentation AN5270:
ACI_GAP_SET_AUTHENTICATION_REQUIREMENT Description Set the authentication requirements for the device. If the OOB_Enable is set to 0, the following 16 octets of OOB_Data are ignored on reception. This command has to be given only when the device is not in a connected state.
but the command does not have OOB_Enable parameter.
tBleStatus aci_gap_set_authentication_requirement( uint8_t Bonding_Mode,
uint8_t MITM_Mode,
uint8_t SC_Support,
uint8_t KeyPress_Notification_Support,

uint8_t Max_Encryption_Key_Size,
uint8_t Use_Fixed_Pin,

uint8_t Identity_Address_Type );
The device I am trying to connect:
My server device I am trying to pair is a legacy device.
It has security mode 1
It has security level : Authenticated 4 LE secure connection with encryption
strict pairing : Yes
IO capabilities: Display
Key press notification : No
Bonding requirement : Bonding
Encryption key size:16
