to get the CSQ
Could anyone please help me how can I get the CSQ of my network signal and how would I know that my board is connected the network?
How can run the AT commands.
Waiting for your positive reply.
@radheshyam0508 You can always write a python script which contains all the commands you want, and store that on the device.
Hey sorry Robert I am asking you more questions.
Now I want to know that can I send all the AT command using the python code. I don't want to send it manually. Is it possible that i can upload the AT command code with the connection establish code?

@radheshyam0508 It respond to AT commands when NOT in data state.
You could also try to send
and then, after a few seconds
These are the historic commands to terminate a data session.
So when does it reply to AT commands? When it is in DATA state or other state?
@radheshyam0508 Yould you try lte.deinit()?
It is funny that the modem is in the data state, if you did not attach or connect. Typically it is in the data state after connecting.
after giving the AT command I got this error...
"OSError: LTE modem is in data state, cannot send AT commands"
Could you please help me how can I rectify it. I already disconnect and reconnect the module and try to send the AT commands but again I got the same error.
@radheshyam0508 Look at the example in the documentation:
which is similar to my little script I posted before. After connection, I tried a simple connection link to a PC I had set up as the server:
data_client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # ip_address="18.104.22.168" port_number = 4567 data_client.connect((ip_address, port_number)) while True: msg = input("New message") if msg == "q": break data_client.send(msg + "\r\n") data_client.close()
I lost somehow the code of the matching "server", but it was minimal. I may have type that on-the-fly at a Python REPL.
sorry, but How would i know that my device is connected?
@radheshyam0508 Once the device is attached and connected, you can use the usual socket mechanism to communicate.
Thanks a lot Robert,
Could you please send me the code for connecting the fipy NB-IoT module to the network.
Because there is no tutorial or example code for NB-IoT.
Thanks a lot for your help and support
@radheshyam0508 You could try this:
from network import LTE lte=LTE() lte.attach() lte.send_at_cmd("AT+CSQ")
Returns for me:
returns the attach status. A typical small test script would be:
# from network import LTE import time import socket start = time.ticks_ms() lte = LTE() print("\nModem started, time needed (s): ", time.ticks_diff(time.ticks_ms(), start)/1000) start = time.ticks_ms() lte.attach(band=8, apn="iot.1nce.net") while not lte.isattached(): time.sleep(0.5) print(".", end="") print("\nAttached!, time needed (s): ", time.ticks_diff(time.ticks_ms(), start)/1000) start = time.ticks_ms() lte.connect() # start a data session and obtain an IP address while not lte.isconnected(): time.sleep(0.5) print("-", end="") print("Connected!, time needed (s): ", time.ticks_diff(time.ticks_ms(), start)/1000)
