We are observing connection problems with the EC25-EU LTE module and would like to try out the latest firmware.
Our host-processor is a Raspberry Pi CM4 running a custom Linux distribution built using Yocto.
Could someone please:
- Provide the latest firmware for the LTE module.
- Provide tools and/or instructions on how to update the LTE module via USB from an embedded Linux platform.
The LTE module is specifically: EC25EUXGA-128-SGNS.
Please send via private message.
Can I ask what firmware version you are currently using and where you are using the module?
@lyman-Q Can you provide instructions on how to read the firmware version? So far, I am have simply used quectel-cm to set up a data connection.
The LTE modules are used in Denmark.
You need to compile the Linux module driver first, then check whether the USB port is displayed normally, and then enter the AT command interface through the busybox microcom /dev/ttyUSB2 tool. You can check the current firmware version through the AT+QGMR command. By the way, which region are you using the module in?
The response is:
The region that the LTE module is used in is Denmark, Europe.
I have send the latest firmware and flash tool to you by chatbox,pls chk.
