LE910C1 HTTP Connection Issue

  1. I have to be missing something simple in my connection. Ultimately I want to connect to a mqtt broker but I figure I would take baby steps and just try to connect to a http connection first. Here is my command sequence and response:

    AT#HTTPRCV=0

    ERROR

    I dont get the ring response for some time which tells me its timming out. As well as there is no data along with the response. The html page I’m contacting is just a simple hello world page to verify connection.

    I know the LE910 works and I have internet connectivity. I connect to a UDP port on my test server and dump data all day long with at#sd. Do I need to establish a SD connection to the server as well for TCP?

    1. It works well with my LE910-EU-V2, see the log below.

      Set AT+CMEE=2; check AT+CEER and ATCEERNET.

      1. Still no joy on my end. My module is the Sprint version of the LE910.

        Looks like ling times out as well:
