Unable to connect to AT Command ComPort in Windows 10 for FX30

IoT Gateways FX30
1

Hi,

I am new to Sierra Wireless FX30S ( serial port ). I had installed generic windows driver from sierra website into my windows 10 laptop.
I can see Sierra Wireless AT Command port (Com10).
FX30 is powered up with its standard cable and USB B micro is connected to usb port, SIM card is inserted in SIM slot.

I am trying to connect using putty(serial connection) and not able to connect to AT / Sierra Wireless FX30 to access AT Command. I tried using 9600/38400/11500 / 8 N 1 baud rate, party stop bit. None was successful.
Your support in this is very appreciative. Kindly let me know if there is some thing that i am missing here.

Hi @Guruk,

I would advise you to start by having a look to the FX30S User Guide where this topic is addressed:
https://source.sierrawireless.com/resources/airlink/hardware_reference_docs/airlink_fx30s_hw_user_guide/

By default FX30S RS232 interface is not set for AT command. However, it is possible to configure it for this purpose:
On the Sierra Wireless AT command Port:

at!mapuart?

!MAPUART: 17,17

OK

at!mapuart=1,1

OK

at!reset

OK

Wait for the modem to reset.

at!mapuart?

!MAPUART: 1,17

OK

At this stage, you’ll be able to send AT commands on the UART @ 115200 bps

To restore initial config use AT!MAPUART=17,1

Please note that PPP Dial-up is not supported opn this product.

Hope it helps,

@guruk,

If you send at!pcinfo? to the unit it wil tell you why it is in low power mode. You could also try sending at+cfun=1 to force it into full power.

OK

But cm data in SSH is showing no connection.Please refer below,

root@fx30s:~# cm data
Index: 1
APN: airtelgprs.com
PDP Type: IPV4V6
Connected: no

@guruk,

That’s because you need to start the connection with the below command.

cm data connect&

The & is important so that it goes back to the command prompt once the connection is up (or else you have to start another SSH session with the unit.
