Library features a Sans-IO core with both asyncio and blocking wrappers:
from pandablocks.blocking import BlockingClient
from pandablocks.commands import Get
with BlockingClient("hostname-or-ip") as client:
# Commands sent to Control port
idn = client.send(Get("*IDN"))
print(f"Hello {idn}")
for data in client.data():
# Data captured from Data port
print(f"I got some PCAP data {data}")See https://pandablocks.github.io/PandABlocks-client for more detailed documentation.
