Hello, could you explain the difference between the RM520F-BL, RM520F-EU, RM520F-GL, and RM520N-GL modules? Is there a difference in the firmware of these modules?
Also, I have an RM520F-GL module, and it seems to have what looks like custom firmware installed. Can you send me the latest firmware version for this module? It’s currently acting strange and doesn’t accept all AT commands.
Dear @v6746aap
These modules use different firmware.
For RM520F-GL,it only have firmware, I will sent to your email, please check later.
Can you please send it to me too? Thanks!
I remember that I was on this version before, I had documented it, but I forced it into 9008 mode, and now I have to flash the firmware in order to exit it, so could you please send me the latest version, thank you engineer.

Dear @Semsem
Please share your current firmware.
Dear @Dale
I have sent to your email, please check.
Hello, thank you for your support. I will continue to accompany Yiyuan further. Thank you, after I flashed the firmware, it booted up, but it seems that the baseband is missing. When I queried AT CFUN?, it showed 5. I need to write the QCN baseband file. Could you provide the QCN baseband file? Or could you provide the engineering package firmware? My email is 935341417@qq.com.
Dear @Dale
I have sent QCN to you via Message, please check.
Hello, could you please send me a copy of the latest firmware and QCN file for the RM520F-GL?
I have a question: In China, the RM520F-GL can only support aggregation of different frequency bands such as N41+N79, and cannot support aggregation of two same N41 frequency bands. Is this a hardware limitation or an issue with the baseband file?
Compared with the MT5700M-CN, Quectel has much better signal performance, but its aggregation modes are relatively limited.

Dear @tyllzsg
Why do you want QCN? Is there any issue on your side?
This module doesn’t support n41+n41 due to hardware limitation.
Hello dear @silvia Can you please send me qcn for the rm520f-gl? I made a mistake and erased mine. I appreciate your help. Thanks!
Please confirm your current firmware version. Thx.
