I am struggling for the past few days to send an e-mail with the SIM5300 3G module, but in vain. I had no success so far and I really cannot understand what I am doing wrong.
The SIM5300E 3G module has different AT commands from SIM900 or SIM5320 modules.
I am using an Arduino Mega 2560 with a trivial sketch to send AT commands to the 3G module.
Please find attached the Arduino code and the communication with the 3G module.
Has anyone of you had any experience with SIM5300E?
Thank you in advance.
