FiPy and NB-IoT with new Pycom/Vodafone SIM

[patmolloy]

I have one of the new Sims. I have updated both the main firmware and the sequans firmware to the latest versions (sequans NB-IoT code). I have registered the sim in PyBytes and I think it all looks alive and good. The following code appears to suggest that the basic connectivity is there, but I get the following error .. can anyone help? It does look like that attach and connect are working!

>>> Running selected lines

>>> 
>>> 
Apparently attached
Apparently connected
Traceback (most recent call last):
  File "<stdin>", line 18, in <module>
OSError: [Errno 113] ECONNABORTED
>

The code is ..

import socket
import ssl
import time
from network import LTE

lte = LTE()         # instantiate the LTE object
lte.attach(band=20, apn="pycom.io")        # attach the cellular modem to a base station
while not lte.isattached():
    time.sleep(0.25)
print ("Apparently attached")    
lte.connect()       # start a data session and obtain an IP address
while not lte.isconnected():
    time.sleep(0.25)
print("Apparently connected")
s = socket.socket()
# s = ssl.wrap_socket(s)
s.connect(socket.getaddrinfo('www.observat.io', 80)[0][-1])
s.send(b"GET / HTTP/1.0\r\n\r\n")
print(s.recv(4096))
s.close()

lte.disconnect()
lte.dettach()

The OSError is on line 18 which is the

s.send(b"GET / HTTP/1.0\r\n\r\n")
