Hello, we are using a RG500Q-EA module on a network in which we have two applications. In the first one we use modemmanager to manage the connection and the module is working correctly. On the second application we need to use AT commands to open a TCP socket and it is failing to open. Additionally, pinging the server is not successful. From the modem working with modemmanager both operations are completing. These are the AT commands we are using:
AT+C5GREG?
+C5GREG: 2,1,"1FA5","B3B101",11,0,""
AT+QENG="servingcell"
+QENG: "servingcell","NOCONN","NR5G-SA","TDD",999,40,B3B101,29,1FA5,475970,40,3,-74,-11,22,1,-
AT+QIACT=1
OK
AT+QIACT?
+QIACT: 1,1,1,"172.26.1.241"
AT+QIOPEN=1,2,"TCP","88.30.42.137",1887,0,1
OK
+QIOPEN: 2,566
AT+QPING=1,"88.30.42.137",10,10
OK
+QPING: 558
How could we troubleshoot the connection in the modem that is not working? Thank you in advance.
