Hi,

I recently got a mangoh-red board with wp7603 and a starter Sierra-Wireless 100MB SIM card.

The mangoh/legato firmware / app framework build and installed worked as described in the getting started guide. I registered the mangoh-red system in AirVantage using the IMEI.

I have run into an issue with network connectivity that I hope you can help with.

I am powering on the mangoh-red module in Maryland/USA with the Sierra-Wireless SIM card and the module is connecting to AT&T network . However it is only connecting to UMTS n/w (not LTE) and is failing registration. I am also not seeing any status information for this device on AirVantage

The result of cm radio is  
Power: ON  
Current Network Operator: AT&T  
Current RAT: UMTS network (LE\_MRC\_RAT\_UMTS)  
Status: Registration was denied, usually because of invalid access credentials (LE\_MRC\_REG\_DENIED)  
Signal: Weak signal strength (2)  
PS: Packet Switched Not registered (LE\_MRC\_REG\_NONE)

The results of cm sim info is  
Type: EXTERNAL\_SLOT\_1  
ICCID: 8933240100000630xxxx  
Home Network Operator: Proximus  
EID:  
IMSI: 20601882194xxxx  
Phone Number:

I also tried changing the APN from “[internet.sierrawireless.com](http://internet.sierrawireless.com)” to “NXTGENPHONE” for AT&T and still couldn’t get connected.

result of cm data :  
Index: 1  
APN: NXTGENPHONE  
PDP Type: IPV4  
Connected: no  
here is the CM info results:  
Device: WP7603  
IMEI: 35740908010xxxx  
IMEISV: 4  
FSN: U3746286290610

Bootloader Version: SWI9X07Y\_02.14.04.00 000000 jenkins 2018/02/14 20:19:41  
MCU Version: 002.007  
PRI Part Number (PN): 9906965  
PRI Revision: 002.003  
Carrier PRI Name: GENERIC  
Carrier PRI Revision: 002.025\_000  
SKU: 1103194  
Last Reset Cause: Power Down

Please let me know what I am missing here.  
Thanks.

Hi,

Can you go into the serial port of the unit from your PC/Linux machine and send the following to double check a few things.  
ati  
at!gstatus?  
at+cmee=1  
at+cops?  
at!band?  
at!selrat?  
at+cops=? //This one will take a minute or two to complete and will show if the unit can see the AT&T LTE network  
at+cops=1,2,“xxxxxx”,7 //The xxxxxx is the MCC/MNC for AT&T given in the above result (assuming it can see the network

This should give a better idea about what is going on.

Regards

Matt

Hi,  
Thanks for your note. I tried issuing the AT commands - ati , at!gstatus? etc. However, the serial port (in my case COM6 @ 115200 baud) …response was that command not found.

Here is the console print that I see on COM6 on power up:

Hi,

So you are looking at the physical UART2 here which is outputting the console of the Legato frame work, can send the AT commands from here after the dvice has fully booted up and use microcom (Linux terminal program) to connect to the internal AT channel using the below command  
microcom /dev/ttyAT

After you hit enter nothing will appear to happn but if you send at it will respond with OK, you can then send your AT commands.

Alternatively what I was originally envisaging was you connecting to the AT port on the host system, if the host system is Linux then it will be /dev/ttyUSB2 (assuming there are no other /dev/ttyUSB’s already enumerated). If it is a Windows system it could be anything but you will find it in the control panel device manager either under ‘Port’s’ (probably) or ‘Modems’ (less likely).

Regards

Matt

mlw,

I’m having the same trouble with my mangOH Red WP7603 registering to the AT&T network. I’ve tried two versions of the latest firmware: R9 (Generic - GCF) and R9 (AT&T). Neither seemed to work, though. Here are two of the most common statuses …

and/or

> Not registered and not currently searching for new operator (LE\_MRC\_REG\_NONE)

Here’s the detail on my module as well as the output from your suggested AT commands.

Hi,

Couple of things to try.

Check out the APN’s that you have configured on the unit using the below command  
`at+cgdcont?`

When attaching to LTE it uses both the IMSI and the APN, because you have the AT&T PRI file activated it could well be that you have the AT&T APN setup but because you are using a SWI card it needs a different one (I think it is [internet.sierrawireless.com](http://internet.sierrawireless.com)).

Second thing to try is forcing it to the 3G network and not the LTE one which it will automatically go for because it can see it. When attaching to 3G it does not need an APN, it it does attach it will confirm that the SIM is active and the roaming is working.  
`at+cops=1,2,"410310",2`

After the above make sure to set it back to automatic with at+cops=0 otherwise it will only ever want to go onto AT&T 3G regardless.

Last thing to use would be a PAYG SIM from AT&T as this cuts out all of the roaming issues and then setting the APN manually using the below.  
`at+cgdcont=1,"IP","xxxxxx"`

Regards

Matt

</div>

mlw,

Thanks for all of the suggestions!

I flashed the module with the generic firmware since that’s what the guide suggested. I only went to the AT&T version in hopes that would connect. Plus I’d like to stay as close to the default setup as possible.

So here’s what APNs are in use …

**AT Interface**

```
at+cgdcont?
+CGDCONT: 1,"IPV4V6","internet.sierrawireless.com","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

```

**Linux Interface**

```
root@swi-mdm9x28:~# cm radio
Power: ON
Current Network Operator: AT&T
Current RAT: UMTS network (LE_MRC_RAT_UMTS)
Status: Registration was denied, usually because of invalid access credentials (LE_MRC_REG_DENIED)
Signal: Strong signal strength (4)
PS: Packet Switched Not registered (LE_MRC_REG_NONE)

root@swi-mdm9x28:~# cm data
Index: 1
APN: internet.sierrawireless.com
PDP Type: IPV4V6
Connected: no

```

I tried to force it to use 3G without any luck. You suggested “410310” so I tried that along with what was originally reported “310410.” Neither worked, though.

```
at+cops=1,2,"410310",2
+CME ERROR: SIM failure

at+cops=1,2,"310410",2
+CME ERROR: no network service

```

So here I’m back to where I started.

</div>

Hi,

My mistake on the network number, you did the right thing by trying the one that was actually suggested.

What I would suggest is that the SIM is not activated which is why it is being rejected, not sure if it came with any activation instructions?

Regards

Matt

mlw,

That was it! I didn’t register the SIM because I didn’t know I needed to. I was following the mangOH Red Getting Started Guide (Linux) word for word. It walks you through configuring the hardware, then the dev environment and finally registering it to a network. It mentions different types of SIMs and their respective APNs, but no talk of activating them. Maybe that’s just common sense? I don’t know. Would be nice if the SIM card at least had a label telling the user they need to activate it. Oh well, my bad in the end.

Regardless, thanks for all of the help! Off to programming …

Thanks Again!

Hello guys

What firmware do you use with WP7603 for North America with Sierra sim?

AT&T or generic ?

Thanks

Francis,

If you are using a Sierra SIM go with the generic, the AT&T version is tested/approved with an AT&T SIM but generically it should not make that much of a difference.
