How do I change the block size in a GET request?

[kustovnd]

Hi. I'm new to CoAPhton.
There is a simple question: how to change the size of the requested block in a GET request?

I have the following code:

from coapthon.client.helperclient import HelperClient
from coapthon.utils import parse_uri
client = HelperClient(server=("bbbb:8542:bbff:2:fc9e:48d0:a8de:14f5", 5683))
response = client.get
client.stop()

By default, a block of 16 bytes is requested. I need to change this length to 64. How can I do this?
