How to get all sensor data using raspberry pi

I am using Pi 5. Also, I didn't connect the Pi using the socket as described https://docs.petoi.com/apis/raspberry-pi-serial-port-as-an-interface I simply connected the USB adapter to the NyBoard and the Pi. I don't know if that would be an issue.

I downloaded the branch "better-gyro" and set up the serialMaster files. My code to try to print the gyro data is as follows:

I use the example.py as reference line and I start writing this in line 426

port = list(goodPorts.keys())[0]

for task in testSchedule:
	print(printSerialMessage(port, 'gP'))
	send(goodPorts, task) # Send the skill

However, it seems there is no response, because all I get is -1 from printSerialMessage, which is the timeout condition as the response is an empty string. First, is the token "gP" correct?

Moreover, the output from line 183 in Ardserial.py,

response = port.main_engine.readline().decode('ISO-8859-1')

which is within printSerialMessage() is an empty string when the token is "gP" or "gp", but "k" if the token is "K".

Finally, something worth mentioning is that when I connect Bittle via USB to the Raspberry Pi, it throws the message "Port ttyAMA10 is not connected to a Petoi device!", but I've always been able to send skills, which Bittle executes correctly.

I am unsure where the issue is, or how to fix it. I'd appreciate a little more guidance. And thanks for an awesome project!
