RG801H-EA FIRMWARE and AT network

can you give me the latest FW of version RG801H.

Can this module use AT with network port?
Can you send me the full details?

My email is development0michael@gmail.com

This modem have been EOL for more than 4 years.
What is the IMEI of it?
Please check the message.

I have an RG801 and I want to add the web interface I wrote by adding ADB but I can’t seem to find the AT port?

Is there an example of RGMII_AT_Client available for RG801?
