GUI software description

The following pseudo code describes how to initialize a BlueNRG-MS device as a peripheral

using a simple python script:

# Reset BlueNRG-MS

HW_RESET()

# Init GATT

ACI_GATT_INIT()

# Init GAP as central device

ACI_GAP_INIT(Role=CENTRAL)

When a script is calling a command which generates specific events, the script can detect

them by using the WAIT_EVENT (event_code=None, timeout=None,

continueOnEvtMiss=False, **param_checks) command.

GET_LIST

Integer, Number of

bytes

Convert the integer value to an array of Number

of bytes.

Example:

X = 0x2233

GET_LIST(X, 2) = [0x33,0x22]

GET_STACK_VERSION

None

Return the FW stack version as

(major_fw_number,minor_fw_number)

GET_RAND_KEY

None

Returns a random number between 0 and

999999

INSERT_PASS_KEY

None

Allows to enter a pass key value used for the

security pass key method

string

Print utility: it displays information on GUI

Sent/Received Packets

RESET

None

SW reset

SLEEP

time

It sleeps for “time” seconds

SET_MODE

Mode

Set stack mode (1,2,3)

SET_PUBLIC_ADDRESS

Public address

Set public address (optional)

SENSORDEMO_GET_TE

MPERATURE

None

It allows to get the temperature value from the

EVT_BLUE_ATT_READ_RESP event (only for

the SensorDemo_Central script)

SENSORDEMO_GET_AC

CELERATION

None

it allows to get the acceleration values (x,y,z)

from the EVT_BLUE_GATT_NOTIFICATION

event (only for the SensorDemo_Central script)

TIME

None

It returns the time as a floating point number

expressed in seconds since the epoch, in UTC
