QMI about sim7000-lte-shield

[sabareesan007]

Hi all,

@Ben1902 further you can config the band for CAT-M or NB-IOT using "AT+CBANDCFG". In our country we use band 8 for NB-IOT.
@botletics thank you for sharing your valuable work.

Hi there,

First of all, I am not a Linux guy. According to the SIM7000A page the modules does indeed support PPP and according to the AT command manual you can use AT+CGDCONT to achieve that. I personally have not tried it. As for QMI modem interface, I really don't know but I have asked a SIMCom engineer about it and will get back to you if I find an answer.

Best,
Tim

Hello again,

Now I have had some time to test, after my cellular provider finally has fixed CAT-M1 access where I live. Now the QMI interface is working(!), but from what I tried of your AT commands I found elsewhere in an article, it now runs on GPRS. Do you have any idea on how to disable GPRS and force CAT-M1?

Hi there,

Check out the "AT+CNMP" command. You can do "AT+CMNP=38" to use LTE only.

Then, if you further need to force only CAT-M1 and not NB-IoT then you can use "AT+CMNB=1"

Hope that helps!

Seems like this has been resolved.
