RM502Q-AE and at+qeth="eth_at"

Quick update. I manage to compile it by adding this line on the top:
#include <arpa/inet.h>

But now I am unable to connect. I get those errors:

(base) ➜  RGMII_AT_Client ./quectel_client
RGMII-AT Client Up => 192.168.225.1:1555
Can Not Connect To => 192.168.225.1:1555
Can Not Connect To => 192.168.225.1:1555
Can Not Connect To => 192.168.225.1:155

I can connect with telnet, but I get no response from at commands.

Can you please send me the details?
Thank you,
