Example: BLEHIDMouse
(https://github.com/ambiot/ambd_arduino/blob/dev/Arduino_package/hardware/libraries/BLE/examples/BLEHIDMouse/BLEHIDMouse.ino)

Notes and Warnings
“BLESecurity.h” must be included to use the class function.

BLESecurity::setIOCapability

Description
Set BLE device input and output capabilities.

Syntax

Syntax
void setSecReqEnable(bool secReq);

Parameters
secReq: TRUE to enable, FALSE to disable.
Default value: FALSE

Returns
NA

Example Code
NA

Notes and Warnings
“BLESecurity.h” must be included to use the class function.

BLESecurity::setSecReqFlags

Description
Set security request requirements.

Syntax
void setSecReqFlags(uint16_t secReqFlags);

Parameters
secReqFlags: desired security requirements.
Valid values:
– GAP_AUTHEN_BIT_NONE
– GAP_AUTHEN_BIT_BONDING_FLAG
– GAP_AUTHEN_BIT_MITM_FLAG
– GAP_AUTHEN_BIT_SC_FLAG
– GAP_AUTHEN_BIT_SC_ONLY_FLAG
– GAP_AUTHEN_BIT_FORCE_BONDING_FLAG
Default value:
– GAP_AUTHEN_BIT_NONE

Returns
NA

Example Code
NA

Notes and Warnings
“BLESecurity.h” must be included to use the class function.

BLESecurity::setStaticPin

Description
Configure device to use static pin input for BLE bonding.

Syntax
void setStaticPin(uint32_t pin);

Parameters
pin: BLE bonding static pin. Valid values are 6-digit integers ranging from 000000 to 999999.

Returns
NA

Example Code
NA

Notes and Warnings
Using a static pin will enable BLE bonding and pairing, set the IO capability to GAP_IO_CAP_DISPLAY_ONLY and set the bonding security requirements flags to (GAP_AUTHEN_BIT_BONDING_FLAG | GAP_AUTHEN_BIT_MITM_FLAG | GAP_AUTHEN_BIT_SC_FLAG). “BLESecurity.h” must be included to use the class function.

BLESecurity::setPasskeyDisplayCallback

Description
Set a user callback function for passkey display during BLE bonding.

Syntax
void setPasskeyDisplayCallback(void (*fCallback) (uint8_t conn_id, uint32_t passkey));

Parameters
fCallback: A user callback function that returns void and takes two arguments
conn_id: connection ID of connecting device
passkey: bonding passkey to display to user to confirm connection

Returns
NA

Example Code
NA

Notes and Warnings
“BLESecurity.h” must be included to use the class function.

BLESecurity::setPasskeyInputCallback

Description
Set a user callback function for passkey input during BLE bonding.

Syntax
