Error: could not open port #2

Closed drgagi closed 4 years ago

drgagi commented 4 years ago

$ nbiot --port 14 connect Error: could not open port '14': FileNotFoundError(2, 'The system cannot find the file specified.', None, 2)

My device is using port 14 and can connect with putty serial.

Krolken commented 4 years ago

It might be that your port is named differently on system level.

Are you on Linux/MAc or Windows?

on Linux/mac you run 

ls /dev/tty*

to list your available ports.

drgagi commented 4 years ago

Windows 10, it is COM port 14 listed in device manager.

I tried on Ubuntu, passed connection part but failed on some point with cause "Error on AT Command":

OK. Your device responds with ERROR to the AT+CFUN=1 command. Not really sure why.

On windows don't you have to specify COM14 and not just 14

drgagi commented 4 years ago

SIM contact was not ok so module could not detect sim card and that was the reason why it fails. Maybe you can add one more check for this. Try AT+CIMI which return IMSI number located on SIM card. If this command returns error it means no sim card inserted or connectors are bad so module can not detect sim. You can add this as warning. Anyway I succeed to make connection, I got IP address and everything loos fine but script stooped on "Awaiting Connection". What exactly script is waiting for?

I add --home-network at it works. Thank you.

Krolken commented 4 years ago

Perfect. Yeah home-network vs roaming can be a bit annoying. First I only had foreign SIMs that required roaming and then I had to implement the home-network since I got Swedish SIMs.
