import ubluetooth as bt

from ble_uart import BLEUART

from tools import BLETools

from const import BLEConst

from machine import Pin

def rx_callback(data):

print((data))

if (data) == (b'on'):

Pin(12, Pin.OUT).value(1)

if (data) == (b'off'):

Pin(12, Pin.OUT).value(0)

ble = bt.BLE(); uart = BLEUART(ble, rx_callback,name="esp32_ble")
