Support driver installation for EM7565

Hello! How can I install driver for EM7565 on windows 10. I am having problem by mistake between EM7455 when changing following parameters for EM7565:

I can still flash the firmware on windows 10 but since the driver cannot be installed, I cannot send AT command to the module. I used em7565 with an M.2 card to usb 3.0 . adapter

Can anyone help me to reset default for EM7565. I appreciate your help. Sorry my English is not native English


What is your sku? AT!ENTERCND=“your password” and AT!SKU?

The full process command I set is:
After that, Windows 10 does not recognize the driver anymore. I can’t set the COM port to be able to send AT commands to the module anymore.
I tried again on ubuntu 20.04 also can’t connect to module.
I do not save the SKU code.
But my module can be a sample version.

Now how can I restore from scratch so I can install the driver?

The SKU should be on the modem’s top label/cover. It’ll be a 7 digit number. You can hack the Linux serial driver to support the PIDs that you have set the modem to. The driver should then enumerate the ports for AT access.

I only have information like this photo. Before the crash I saw the SKU in the ATI command line but didn’t save that value. :sob:
Edit: I found the IMEI number in a photo I took while flashing the firmware : 001022009999999

This modem is a very early sample. It will be better to use a production modem for your development. Please reach out to our sales department and you can purchase a modem. Please use this link Contact Sales | Sierra Wireless. Thanks.

Thanks :pray: :sob: I still want to know how can this error be fixed

Since you don’t have AT access, there is not much we can do via the forum. Please reach out to your Sierra Wireless or distributor support/sales channel and we can help you via those channels. Thanks.

Thank so much. I will send it to distributor

modprobe option
echo 1199 0071 >  /sys/bus/usb-serial/drivers/option1/new_id

and you will have AT access again via onne of the /dev/ttyUSBx devices showing up. Use it to fix your typo

Oh thank you. I will try it

Thank you very much. I was able to access my module again. Other problem I’m still having. Currently it is saying no service. Maybe the problem lies in the module itself. I have another EM7455 module using the same M2 converter card, the signal is very good.
