If I set my EM9293 on factory test mode, would I be able to connect to the internet on it?
I want to know because the AT!DARCONFIG command would allow me to set a channel number but only if I’m in factory test mode. My goal is to browse the internet on different channels in LTE bands, as part of my test.
You should configure your CMW500 machine to have internet option
After that module should work in normal mode
Is there any Sierra modem that can set the channel (EARFCN) or PCI on its own without a separate testing device?
you can see here:
BTW, I can also see the MBPL SDK sample application lite-qmi-nas, there is “Get Cell lock Config” and “Set or Clear Cell Config” for locking PCI:
I can’t seem to find “Get Cell lock Config” or “Set or Clear Cell Config” in the lite-qmi-nas README. Do you know where I can find that info? That’d be ideal if I can do that.
you need to see the source code command_set.c:
{
"GetCellLockConfig",
"Get Cell lock Config",
0,
NULL,
eGET_CELL_LOCK_CFG
},
{
"SetCellConfig",
"Set or Clear Cell Config",
sizeof(g_set_cell_cfg) / sizeof(ARGUMENT_SET),
g_set_cell_cfg,
eSET_CELL_CFG
},
I don’t see that in my command_set.c. I even just re-downloaded the SDK from the link above.
Path I checked: MBPL_SDK_R44_ENG5-lite.bin/SampleApps/common/src/command_set.c
then you need to contact distributor to get the full source code of sample application lite-qmi-nas
Or you can directly run the binary of sample application lite-qmi-nas
Tried the binary of lite-qmi-nas. As soon as I executed it, my lte signal freezes and the blue LED on my usb adapter stays on (doesn’t flash like it’s supposed to when connected). So, even though there was an option to “get the cell lock config” and to “set or clear cell config”, it returns an error.
Is there a reason I can’t run lite-qmi-nas while connected to LTE? Also, is there a latest modem that will support the AT!celllock for 3g/4g/5g? The MC7304 from the linked post doesn’t support those.
I don’t see problem to run the application:
owner@ubuntu:~/QMI/MBPL/MBPL_SDK_R44_ENG5-lite.bin/SampleApps/lite-qmi-nas$ sudo ./bin/lite-qmi-nashostx86_64

I get this too. After some time, it says Transport callback is invoked, type:1, value: 11. Also, what does it mean if “0 element(s) are in Cell List”; does it mean I can’t select one then?
did you check AT!GSTATUS?
If it is attached, then that means your observation of LED is not related…
yes it’s attached according to AT!GSTATUS, but can’t browse the internet.
Can you get IP address then?
BTW, below was my testing with EM9191 on this sample application:
1. Connect the EM9191 module which originally attaches to cell ID 328 with EARFCN 1850 and cell ID 326 is a neighbor cell:

8. Now if I enter AT+CFUN=0 and clear the cell locking list by entering <ENTER> key in option "41", after AT+CFUN=1, it will attach to original cell ID 328 as step 1 above.
Thanks! So for my raspberry pi, I had to run the lite-qmi-nasarm binary for it to work (not nasrpi). Also, for it to connect to internet again (and LED to flash properly), I have to re-plug the usb adapter for the modem.
BTW, when I try to clear the cell locking list by pressing enter key in option “41”, It says SetCellConfig errorCode: 1090 - Incompatible State. How can I clear the list?
did you do it after AT+CFUN=0?
Thanks again, that was it
Is there a way I can avoid having to restart my modem to browse the internet after locking to a cell? I have tried AT+CGATT=1 and AT+CGACT=1,1 and AT+CGDCONT but none of them allow me to browse the internet. I checked AT!GSTATUS and everything looks fine (PS state is attached, EMM state is registered)
Only a full restart using AT+CFUN=1,1 or AT!RESET fixes it but I want to avoid that since it takes time.
how about AT+CFUN=0 and AT+CFUN=1
Still no luck, is there any other way of doing a restart without actually doing a restart?
