I have downloaded drivers and flashed the modem to the latest firmware. I can connect through qcom and have set at+qcfg=“usbnet”,1. Set apn set IMEI and nothing.
At+qeng=“servingcell” shows limserv and my computer doesn’t even recognize it as a modem. I have read and read but it seams I am the only person to have this problem. Did I get a bad module or is there something I am missing?
Dear @Hogtiednaked
Please share a picture of device manager.
Which driver did you install?
For limsrv, did you test with another SIM card?
I keep getting +QLWURC: “bootstrap”,”failed”,100
What does that mean?
Dear @Hogtiednaked
+QLWURC is used for LwM2M.
Do you install the module into PC directly?
Please check the AT command below:
AT+QMBNCFG=“List”
no it is in an m2m ethernet enclosure

Hi. I live in Russia, this module does not work. LIMSRV always writes that it cannot connect to Russian networks. It’s a pity that Quectel did this to people, it’s a pity.

Because it is a Qualcomm modem. It’s the US government ordering their compnies to ban Russia from their products. I hope you can return it and get your money back.

The firmware update log states the reason.
RM551E might be the same.
You may be able to return it for a refund and find a non-Qualcomm platform alternative.

Dear @Hogtiednaked
Could you try to use Row and test again as follow?
AT+QMBNCFG=“Deactivate”
AT+QMBNCFG=“Autosel”,0
AT+QMBNCFG=“Select”,“ROW_Commercial”
AT+CFUN=0
AT+CFUN=1
Now I’m getting +QLWURC:”pdp active”,”failed”,”ims”
Dear @Hogtiednaked
Please confirm if you use LwM2M feature, QLWURC is related with this.
After configur row, did it register?

How do i know if LwM2M is turned on?
Dear @Hogtiednaked
Actually, the device has registered on LTE network.
For LwM2M, please check if youe MCU code had implemented the feature.
For RM551E, it doesn’t support this now.
I don’t know what the mcu code is.
Everything seems to be right. I can query the modem in device manager and get a response but it still does not show up as an internet option. I have uninstalled and reinstalled drivers a dozen times. Have tried different cables even a different enclosure. Still not able to get an internet connection to my computer.

=>From this, you had register on LTE.
Did you have data call?
How can I make a data call?
