def angelbrok_login():
try:
global feed_token, client_code, angel, password, totp

	angel = SmartConnect(api_key="")

	qrOtp = " "
	totp = pyotp.TOTP(qrOtp)
	totp = totp.now()

	data = angel.generateSession(client_code,password,totp)
	refreshToken = data['data']['refreshToken']
	feed_token = angel.getfeedToken()
	print("Login successful")
except Exception as e:
	print("Error in login", e)

Note: once you login successfully, do not try to generate again,
who will resolve my "In on pong function==> b'\x00'" issue ?
