@jcaron Okay I've replaced the Amarisoft sim to a Verizon one which uses band 13. I've also adjusted the code but I'm still having issues with attaching. Any ideas?
import socket
import time
from network import LTE
import ssl
import machine
from network import WLAN
wlan = WLAN(mode=WLAN.STA)
lte = LTE()
def connect():
print('lte.attach()', end='')
lte.attach()
while not lte.isattached():
print('.', end='')
time.sleep(0.25)
print('Connecting to LTE network', end='')
lte.connect()
while not lte.isconnected():
print('.', end='')
time.sleep(0.25)
print('LTE is connected')
def disconnect():
lte.disconnect();
lte.dettach();
def at(s):
print(lte.send_at_cmd(s))
def google():
s = socket.socket()
ss = ssl.wrap_socket(s)
i = socket.getaddrinfo('www.google.com', 443)[0][-1]
print('Connecting to socket...')
ss.connect(i)
print('Send...')
ss.send(b"GET / HTTP/1.0\r\n\r\n")
print(ss.recv(4096))
print('Close...')
ss.close()
def wifi():
wlan.init(mode=WLAN.STA, antenna=WLAN.INT_ANT)
nets = wlan.scan()
for net in nets:
if net.ssid == 'Test':
print('Network found!')
wlan.connect(net.ssid, auth=(net.sec, 'Test1234'), timeout=5000)
while not wlan.isconnected():
#machine.idle() # save power while waiting
print('.', end='')
time.sleep(0.5)
print('WLAN connection succeeded!')
break
