EM7511 Cannot Connect to the Verizon Network

[kevin.hoover]

I have a Panasonic FZ-55 with an EM7511 wireless card installed. I have updated all the drivers/bios for the Panasonic and the Sierra card and I am still unable to connect to the Verizon Network. I have spoken to Verizon and they told me the SIM card was not seen by the network, so I installed it in my phone and was able to activate it that way. When I open the cellular connections, I am not seeing any APN settings and under Network it just says Verizon Wireless No Service for the card. Don’t know what step I should take next to get this card working.

Here’s the problem I’m having now. I uninstalled and updated the drivers for the device again and now I’m getting this alarm when I’m trying to query the modem.

I went ahead and changed my Putty to COM 9 and this was the response I received back from the device. I don’t know if this was going to the modem or not.

Com9 is nmea, not modem port

[fordsierra1]

is there any windows software with Gui to use these modules and their gps etc?

[jyijyi]

how about this?

Skylight Windows Connection Manager for EM/MC series modules

[fordsierra1]

ok, but what about the Gps apps

[jyijyi]

How about Skylight GPS Monitor?

EM7455 GPS Monitor

Hello forum, I have installed a Sierra Wireless EM7455 module in a Nuvo 5104VTC with Windows 10. LTE and connection to a mobile network works without problems. However, I have a problem with the GPS reception. When I start the Skylight GPS Monitor and click on the “Start Tracking” button, “Session started, acquiring location …” appears. No matter how long I wait, nothing changes. Do I connect with Putty on the NEMA Com Port but I see GPS data. Why does not the GPS monitor show anything? I on…

[fordsierra1]

ok, but apps for windows 7?

[jyijyi]

Can you install skylight in win7?

[fordsierra1]

i managed to unpack the appx file now, but the exe is not even launching at all

[jyijyi]

other users can make it work in win7:

EM7430 + Win7 Disconnects

Hello all, I am having an issue with the EM7430 disconnecting from 4G LTE-A randomly, reconnecting but then windows in unable to communicate to the Internet. Windows indicates that it has a new IP, gateway etc but I am unable to ping beyond the interface (interface IP address responds). Enabling and disabling the network interface fails to fix the issue. Flushing the route cache fails to fix the issue. AT!GSTATUS indicates PS Attached Issuing a AT!RESET fixes the issue. Relevant details: F…

skylight 4166 does not allow gps MS Based setting

Skylight 4130 from the developer zone does the same. Could someone enlighten me as to what condition causes the dropdown in GPS settings to choose between Autonomous/MS Based/MS Assisted to be greyed out? Is it something in the device, registry or a file? Again, Watcher 3974 does not have this greyed out.

[fordsierra1]

ok, that might be airprime, but win10 has the separate skylight app in the app store.
the airprime does not detect any card tho… i checked that the 5087 0005 driver package is already installed…

[jyijyi]

what is the
at!ENTERCND=“A710”
AT!USBCOMP?

Does your module work with WIN10 with skylight?

[fordsierra1]

well, now i managed to reinstall the drivers somehow and now it actually gives me com ports to use, but what should the baud rate be and which port could be which and what rate for each also?

i ony get this with 115,2k and 9,6k:
Invalid or no response from the device. Please check the modem port and the baud rate.Disconnecting port COMx

[fordsierra1]

ok, now i downloaded that special sierra atcommand app for 7 days or smth, but which commands should i run then.
and it also suggested to connect with some flow control somewhere…

[jyijyi]

You can use tera term to open the modem port to type AT command

[fordsierra1]

ok i try that, but the sierra at app also gives this error:
No NMEA data found in COMx. Please check the NMEA port…

what speeds should i use tho and what is the DM port?
