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 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="22.214.171.124" 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)
