[python-tulip] help deal with aiomas rpc

[velopokatun]

good afternoon.
I can not understand how to call the rpc method via the pure tcp

This simple server:

import aiomas

class Server:
    router = aiomas.rpc.Service()

    @aiomas.expose
    def ping(self, i):
        print('Ping receive data: {}'.format(i))
        return i


if __name__ == '__main__':
    server = aiomas.run(aiomas.rpc.start_server(
        ('127.0.0.1', 5000),
        Server())
    )
    print('Server run')
    aiomas.run(server.wait_closed())



And this my problem tcp client

import socket
import pickle


MESS = ['ping', [1]]

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 5000))
s.settimeout(1.5)
s.send(pickle.dumps(MESS))
data = s.recv(1024)
s.close()



Tell me please what's wrong. It is necessary to understand in order to 
realize this in other languages.Much grateful for any hint
