Raspberry Paramiko Help!

Good morning, I have an issue. I am developing a degree project with raspberry pi 2 and I have to, continuously, collect data every 1µs from a sensor that uses SPI communication and finally to collect those data from a remot client through the SSH protocol in Python with Paramiko module. The SPI communication is already working, but the Python script, in Pycharm, in spite of it seems that it works, is not showing any data y returns a value of 1 when I stop the program. Here is the script:

import paramiko

ssh_servidor = '192.168.0.11'
ssh_usuario = 'pi'
ssh_clave = 'pi'
ssh_puerto = 22

ssh_cliente = paramiko.SSHClient()

ssh_cliente.set_missing_host_key_policy(paramiko.AutoAddPolicy)
ssh_cliente.connect(hostname=ssh_servidor,port=ssh_puerto,username=ssh_usuario,password=ssh_clave)

comando = 'echo %s | sudo ./prueba250118v2' % ssh_clave
entrada, salida, error = ssh_cliente.exec_command(comando)

print salida.read()
print error.read()
ssh_cliente.close()

Start with the posted Python script, focusing on SSHClient.connect and exec_command, and reproduce it against the Raspberry Pi while checking the captured stdout and stderr. Done means the remote command's sensor output is observable through the script and its termination result is understood.
