FX30 CMS ERROR 350 on SMS read AT+CMGL=4

IoT Gateways FX30
1

I am having a problem with an FX30 throwing error 350 when I read SMS messages using AT+CMGL=4 . The same program is also used to read from an FX30S (serial and usb) and an old Wavecom with out any problem. This software has been used for 15 years and the FX30 is the first one I have had issues with.

Below is the sequence that causes the error on the FX30.

AT+CPMS=? [len=9]
[len=0]
+CPMS: (“ME”,“MT”,“SM”,“SR”),(“ME”,“MT”,“SM”,“SR”),(“ME”,“MT”,“SM”,“SR”) [len=73]
[len=1]
OK [len=3]

AT+CPMS=“SR” [len=12]
[len=0]
+CPMS: 0,30,0,30,0,30 [len=22]
[len=1]
OK [len=3]

AT+CMGL=4 [len=9]
[len=0]
+CMS ERROR: 350 [len=16]

Same sequence from the Wavecom

+CPMS: ((“SM”,“BM”,“SR”),(“SM”)) [len=33]
[len=1]
OK [len=3]

AT+CPMS=“SR” [len=12]
[len=0]
+CPMS: 0,5,0,30 [len=16]
[len=1]
OK [len=3]

AT+CMGL=4 [len=9]
[len=0]
OK [len=3]

does problem happen on “SM”?
at+cpms?
+CPMS: “SM”,9,40,“SM”,9,40,“SM”,9,40

OK

After that i can see the content of AT+CMGL=4

3

Yes I am seeing the actual response when using an “SM” , however I am using some older software that has worked through wavecom/raven/FX100. The software queries for the memory locations and polls them all.
There has never been a problem but now the 350 error is somehow causing the software to not work.

I would like to know sort out why I am getting the 350 before I go to the developers and try to get a fix.

4

Can you use ME or SM

5

Unfortunately the current software is programmed to go through all the available locations. I am trying to get the developers to look at it but they want to get an idea what causes the 350 error before doing anything.

i don’t see such problem on my WP76 module:

at+cpms=“SR”
+CPMS: 0,30,9,40,9,40

OK
at+cmgl=4
OK

The only modem I having trouble with is the FX30. I have a FX30s, FX100 and old wavecom that all work. I can not figure what is the difference.

8

What is the module inside your fx30 and fx30s?

Wp76 or wp77?

9

Is there an easy way to tell without taking it apart?

10

if you use WP76, you can use the same FW version as mine and see if there is problem

11

I am just getting back to trying to figuring out what the difference is between the FX30 and FX30S that is causing the problems. The FX30s works. The FX30 fails with a CMS error 350.

Your fx30 is using wp7702 inside.
You can upgrade the fw and see if there is any improvement.

My modem is generic type. do i use Firmware for Generic GCF or PTCRB?

14

if you don’t care about certification, both are ok

15

Tried the firmware but it still has the same behavior.

Command sequence to make it happen:

AT+CPMS=“SR”

+CPMS: 0,30,1,30,1,30

OK

AT+CMGL=4

+CMS ERROR: 350

Hi, Just got a fx30s, updated it and still having the same error. The problem seems to be following the 7702 module (or what ever is different from the previous FX30s). I am urgently trying to get a customer running on this device and I am unable to resolve this.

Current Configuration:
Manufacturer: Sierra Wireless, Incorporated

The problem (error 350) is still occurring with the SR request.
