Hi
I want to print yes in gui.py but it does not get printed because of the json.
How do I fix this. Execute embedded.py and then gui.py to test.
def on_message(client, userdata, msg):
print("message recieved= " + msg.payload.decode())
# print("File which you want to import(with .py extension)")
print("message topic=", msg.topic)
print("message qos=", msg.qos)
print("message retain flag=", msg.retain)

What is the value of the variable called 'name'? Or did you intend that
to be a string?
if msg.payload["name"] == "Hello world!":
print("Yes!")
