Dear @AGYE
I didn’t see RG520NEUAA, could you help to confirm again?
It is better to provide a picture of your module.

Hi! I’m late. This is a photo of the module, it’s an engineering sample

How about it? Do you have the firmware for this module?

Dear @AGYE
As checked internally, due to some reason, this project is pending, so we didn’t have new firmware for it.
