I am using Sim800 GPRS to send data to MySQL server online. I use Arduino mega 2560
for one update in MySQL, it takes 1-2 seconds to run required AT commands
If I use a 4G module like SIM7000E will this be faster ? will update time reduce?
if I use eps32 wifi will this be faster?
in other words which module will give me fast execution and come back to the main loop? sim800 or sim7000e or esp32
