SIMcom7070G PING working code



  • Hi,

    A few days ago, I purchased two development boards. One of them is featuring the SIMcom7070G.

    My location is Germany, I am using a SIM from the Netherlands with Roaming enabled.

    I have not yet managed to send a message through but I can PING 172.27.131.100 - I hope that this module is compatible as it is not one of the recommended or approved one’s.

    Here are the commands for a successful PING: (Some are probably redundant)
