when i use offical Respond to server RPC call example parameter

[alphijiang]

the official example as below:

from psutil import cpu_percent, virtual_memory
from time import sleep
from tb_device_mqtt import TBDeviceMqttClient


# dependently of request method we send different data back
def on_server_side_rpc_request(client, request_id, request_body):
    print(request_id, request_body)
    if request_body["method"] == "getCPULoad":
        client.send_rpc_reply(request_id, {"CPU percent": cpu_percent()})
    elif request_body["method"] == "getMemoryUsage":
        client.send_rpc_reply(request_id, {"Memory": virtual_memory().percent})

client = TBDeviceMqttClient("127.0.0.1", "A1_TEST_TOKEN")
client.set_server_side_rpc_request_handler(on_server_side_rpc_request)
client.connect()


while True:
    sleep(1)

but the SDK does not include client parameters. so I modified the local SDK to fit your official example and use client seems likes to be better for using global variables.
can you add this parameter back?

I can verify this behavior. self is missing in the tb_device_mqtt.py callback in line 294.

Hi , I am facing same issue, but I cannot find the error, where should be placed the "self" . It looks to me like it is already there. thanks

self.__device_on_server_side_rpc_response(request_id, content)

But I still get the error when receiving RPC from server

File "/home/tatu/.virtualenvs/venv/lib/python3.9/site-packages/tb_device_mqtt.py", line 294, in _on_decoded_message
self.__device_on_server_side_rpc_response(request_id, content)
TypeError: on_server_side_rpc_request() missing 1 required positional argument: 'request_body'

Thanks a lot

def on_server_side_rpc_request(client, request_id, request_body): in current SDK not include client parameter, you can use global client , such as below
def on_server_side_rpc_request(crequest_id, request_body):
global client
...

Thanks a lot. After reading and reading, and testing and testing, and more testing, I finally realized whay you meant. heheheh Great , thanks a lot

def on_server_side_rpc_request(request_id, request_body):
global client
print(request_id, request_body)
if request_body["method"] == "getCPULoad":
client.send_rpc_reply(request_id, {"CPU percent": cpu_percent()})
elif request_body["method"] == "getMemoryUsage":
client.send_rpc_reply(request_id, {"Memory": virtual_memory().percent})
