I am using EC200S module and working on linux version 5.2
The problem is the module can not make the connection up .
I tried to make it using AT commands via /dev/ttyUSB1 as well then it behave like this:
+QNWINFO: “FDD LTE”,“46011”,“LTE BAND 3”,1850
It seems the module is not able to register to the network,the sim card has been checked
According to the manual,creg stat should be 1 to do the further operations?
Can you help me with this?
Do i need to update the firmware and Where can i get the latest firmware for this module?
Hello microxp, thanks for your question
Please make sure your antenna is connected well, then reboot your module and query the network registration status via AT+QENG=“SERVINGCELL” conmand. You can also execute AT+CGATT? to query whether the module attach PS domain.
Your module FW is the latest version, so you do not need update your FW, thank you.
After reboot my module
+CME ERROR: 100
Still can not attach to the network
“LIMSRV” means module do not attach to network, please query your SIM card status. You can insert your SIM card into the phone to see if it can be registered.If the problem persists, please grab the exception log email and send it to firstname.lastname@example.org, thank you.
