Hi Dave,

It's good to be back with everyone.

So far, I have been communicating with my Raspberry pi/s by dropping files on the pi/s and/or PH. This mostly works, but it is quite clumsy and not very reliable.
I am seeking a more reliable communication method. So I thought to try socket comms.

I have tried the following code to test:

Formula:   ph_sendsocketdata('192.168.3.YYY', 8500,"Hello from PH_Server." )

Raspberry Pi :

#!/usr/bin/env python3

import socket

HOST = '192.168.3.XXX' # Address of PH
PORT = 8500   # Port of PH

client   =   socket.socket(soc ket.AF_INET, socket.SOCK_STREAM)

from_server = client.recv(4096)
client.send("I am Pi")
print ("From Server: " + from_server)

What happens with this test setup is that PH times out, and the pi crashes on client.recv(...). I'm guessing that the socket never gets created, thus any attempt to comm will fail.

I'd like to hear your thoughts.

P.S. I think I fixed my private email address.
