I have been trying the past 2 weeks to get to the bottom of this, but my SIM808, after upgrading my firmware to the latest, B05, I can finally have SSL encryption.
However, my TCP/IP doesn’t seem to be working and I dont’t understand why because all my initialization steps are as suggested by the majority in the web.
I have T-Mobile as my carrier, and I am using their public APN.
Sequence is as follows:
And after I do this, I get OK, and then the module stucks in the STATE: TCP CONNECTING until it doesn’t reach the server.
For the server side I am using Packet Sender, which I tested with the Socket Server that @Ravi suggested and they both work.
I am in a dead end. Reaching out for help to the engineers out there.
Thank you !
