Hello,
I am using Quectel M66 module. My goal is to establish an http connection. It’s even better for me to install the https protocol, but I get an error on the http connection. I can see the signal strength service provider names. As a result of the CGREG command, I get a response of 0.1. But I couldn’t find where I went wrong. Can you share the http initalize and connection commands?
Hi
Refer to the document I sent you privately, which details the http flow. cgreg: 0,1 indicates that it has been registered to the core network
Hi,
I reviewed the documents you sent, but I couldn’t solve my problem. AT+QIACT command always returns error. What could be the reason for this? I tried different TCP connection. The first response of the QIOPEN command returns as OK, but I get a connection fail right after. Am I missing the configuration tweaks or is there some other command I need to use? Can you help me ?
Hello,
I still can’t establish TCP and HTTP connection. I always get the response of the AT+QIACT command as ERROR. Can you help with this ?
Hello,
I am working with Quectel M66 module. I am trying to establish a TCP or Http connection with the module within the scope of the project. But I am getting error on connection. I am attaching a log file. Can you help me?

Hello,
My problem is solved. When I type internet instead of CMNET in the AT+QICSGP=1,“internet” command, I get the response of the QIACT command as OK. The APN name needs to be informed by the internet or sim card provider.
