Import necessary modules

from pyb import Pin,LED,UART,OLED,delay

Create OLED Object

oled=OLED()

Clear OLED

oled.fill(0) oled.show()

Create BLE Object

ble = UART('BLE')

Initialize BLE

ble.init(57600, bits=8, parity=None, stop=1, timeout=100)

Set to AT Mode

ble.write('+++a') ble.read(10)

Get BLE MAC

ble.write('AT+MAC? ') mac = ble.read(100)[7:19]

Set to Transparent Mode

ble.write('AT+Z ') ble.read(100)

OLED Show MAC

oled.text('MAC:',0,0,1) oled.text(mac,0,12,1) oled.show()

Create LED Object

led1 = LED(1)

Turn on LED1

led1.on()

Loop indefinitely

while True: # Turn off LED1 led1.off() delay(500)

# Turn on LED1
led1.on()
delay(500)

# Send 'Hello World' message through BLE
ble.write('Hello World\n')
delay(500)
