Re: SG-3100 - which cellular module

The one thing that strikes me about this thread is that I feel this problem is a Sierra u3g one. This started for me back on the MC7700 modem.
I used to be able to use the AT command prompt with CU to see connection status with AT!gstatus=? and other AT! tools. This is while connected.
After O/S version change I lost the AT command console when I connected. It would lock me out of cu..
I have not seen the feature since. I am now using MC7355 on FreeBSD and no AT console while connected on that either.
Wonder if the endpoints in the sierra u3g driver are right. Something tells me they are not.
Can anyone see connection stats with AT command console using cu while connected with Sierra modem?

Maybe this came about because of firmware changes and usbcomps on Sierras end.
I know I used to use cu to monitor my cellular connection. Now I cannot.

I have tested the Sierra EM7355 m.2 module and it works.

Sierra used to provide a modem serial port and a AT port they have since discontinued that approach. So unless you have a MBIM or QMI drivers you can't check the signal/status and be connected with Sierra. I have gotten the Huawei ME909s-120 to work but that is a miniPCIe interface not an M.2 interface. Also the Telit LE910 range supports the CDC driver, have only started to test it but is looking promising (but again miniPCIe). The fact that you have an M.2 slot on the SG-3100 means that you are stuck with the Sierra, I'm not aware of any other M.2 device that has driver support in FreeBSD and not EOL or EOS. Netgate might be working on something interesting to see what they do.

There are some Huawei m.2 cards that I believe work but I have not tested them myself.

It is interesting when you look at the hardware it seems like it could do two AT ports if the firmware exposed them. For whatever reason Sierra seems to have chosen not to. With QMI/MBIM I guess there is no reason to.

The ones that i could find from Huawei that are in "sale" are:
1. Huawei ME906s-158 M.2 EU

2. Huawei ME936 - Global

3. Huawei MU736 - 3G/EDGE only

4. Huawei ME916s-168 - not yet released.

I haven't been able to buy 1 & 2 as the company i buy from are out of stock, so if someone else has tested them i'd be eager to hear.
