One note on programming the EM7565. The Huawei Terminal seems to have a conflict with issuing some commands to the EM7565. I recommend you use the Huawei Terminal to locate the COM Port number assigned to WWAN Modem , then use PuTTY in Serial mode to program the modem.
I'm running Linux Mint and Huawei Terminal is in Windows. How do I access the Modem in Putty without knowing which COM to enter in the "Serial Line"? :?:

Hello,
I am learning as well. Sorry didn't know that the MC7455 AT commands where different than what you had. Just done that myself and it had worked. Understand being frustrated with this stuff. Always listen to Jim over others when conflicting info. Good Luck

When you use the link I referenced, you are not logging into the modem. You will be using the router's IP address and logging into the router.

Do I connect to the router via ethernet or wireless?

Much like updating the firmware on a router, it should only be done using an Ethernet cable.

There are enough people who make this mistake of using the wrong AT Commands on the EM75XX modems, that I have been wanting to tutorial on the process. In fact, it is on my list which seems to grow by the day.

Okay I think I'm back to stock. Everything gave me an ok in Putty.
I'm ready to try this again.


at!entercnd="A710"
at!usbcomp=1,3,1009
at+cgdcont=1,"IP","VSBLINTERNET"
at+cgdcont=1,"IPV4V6","VSBLINTERNET"
at!reset

Got all the commands completed.
The Internet light is not coming on and I have no internet when I connect to WiFix.
Powered off then back on, still no internet.

Good job. It is not too difficult of a task (in hindsight at least) but can be a little challenging in the beginning.

Lets first examine the AT Commands you used.
at!entercnd="A710"
at!usbcomp=1,3,1009
at+cgdcont=1,"IP","VSBLINTERNET"
at+cgdcont=1,"IPV4V6","VSBLINTERNET"
at!reset
I assume you understand the first two commands, the first used to authorize change, and the second used to place the modem in MBIM mode. This is actually not necessary since the newer GoldenOrb communicates well with the modem in both QMI and MBIM mode.

The at+cgdcont=n defines an APN profile. When you define the first profile slot (i.e., at+cgdcont=1) with one APN and then redefine the same profile slot (i.e., =1) with a different APN, it over writes the previous APN.

To program two APNs and using your examples above, would look like this:

Code: Select all

at+cgdcont=1,"IP","VSBLINTERNET"
at+cgdcont=2,"IPV4V6","VSBLINTERNET"
Why this is important is that GoldenOrb uses only the first APN profile slot where other firmware and/or routers may use a different numbered profile slot. For instance, Cradlepoint routers seem to prefer the third (=3) APN slot.

Manually programming the modem is really not necessary as GoldenOrb does a great job of programming the first slot via the Modem Profile APN settings--which also must be configured, regardless of whether the APN is manually programmed into modem.

That is usually all that is required "unless" your carrier and cellular plan uses an IPv4 ("IP") only APN. Then, since GoldenOrb uses the APN in the Modem Profile slot and sends an IPV4V6 APN to the modem, this can cause issues. We have only seen this a few times and I am not sure if VSBLINTERNET is one of them or not. If so, there is a tutorial on the forum in changing the script necessary to issue an IPV4 APN as opposed to an IPV4V6 address.

You might first look at THIS post.

Next, and to see what is happening, it is always a good idea to look at the output of:

Code: Select all

AT!GSTATUS?
