FX30S GPRS dial command

Hi guys,

We were supplying Insys GSM Small 2.0 as part of our product, but it is extinct so I’m looking for a replacement. I have a FX30S, but it’s not accepting my ATD command. Here’s my setup and dial attempts:

AT
OK
ATZ
OK
ATH
OK
AT+CSQ
+CSQ: 12,0

OK
AT+CGDCONT=1,“IP”,“myapn.com
OK
ATD991#
ERROR
ATD#GPRS
ERROR
ATD
99

ERROR
ATD99*1
ERROR
ATD

I’ve looked in the manual, but it’s not telling me much, nor are searches on these forums and elsewhere. What am I missing?

Thanks for your help,
Cheers,
ScottCr

How about

atd*99***1#

Also how is at!gstatus?

Hi jyiyji, thanks for the look-in. ATD*99***1# is my default dial string, it also returns error.

at!gstatus?

Interesting that gstatus look all negative. I believe the SIMs are not enabled for 4G yet, but the modem then should drop back to 2G by default (3G is also blocked because the customer was having reliability issues).

Check at!selrat? And see if it is lte only.

at!selrat?
!SELRAT: 12, GSM and LTE Only

So it should do GSM.

Going down the SELRAT rabbit hole, I also checked:
AT+KSRAT?
+KSRAT: 9

I set AT+KSRAT=0, but still get the error on dialling ATD99**1#

Can we set to gsm only in at! selrat

It must be attached before atd99**1#

+KSRAT options:
(RAT index):
• 0—All RATs, automatic
• 1—GSM only
• 2—UMTS only
• 4—UMTS and GSM
• 5—LTE only
• 7—LTE and UMTS
• 9—LTE and GSM

So I tried:
AT+KSRAT=1
OK
ATD*99***1#

AT+KSRAT=2

AT+KSRAT=4

ATD*99***1#

How about using usb AT port to dial up?

i believe you are using fs30s cat m device which is having wp76 module inside, i can make a test on wp76 mangoh board here.

no ERROR is found for usb dial up on WP7608:

USB is not an option. We need this modem to connect to an RTU, which does not have a USB port. I need a drop-in replacement for the Insys GSM Small 2.0. If a £200 modem fails, I need to replace it with another £200 modem, not rebuild the entire £5000 panel to get a modem working.

This is just to see if problem only happened to uart.
I will make a try to wp77 on mangoh board later.

BTW, no ERROR is found for my WP77 to dial up on GSM network:
