Seeking Help with RG520F-JO Module in RNDIS Mode – Device Connection Issues

I am currently facing an issue with my RG520F-JO module after switching it to RNDIS mode. Upon connecting the module to my computer, the Device Manager repeatedly adds and removes the “RG520F-JO” device and shows it as an unknown device. Unfortunately, I am unable to connect to the module via TTL to send AT commands.

Could someone provide guidance on how to resolve this issue? Additionally, I am looking for the latest firmware version and instructions on how to flash the module correctly.

Hi,

Could you show current firmware version in your side? Much appreciation

I can’t connect the module via USB or TTL, so I can’t send AT command to it. I think it’s due to the change of network mode to RNDIS. Is it possible to download the firmware to reset it’s under this situation?

The last time I ran ATI command returns with “RG520FJOAAR05A01M4G_OCPU_”
