First use of GSM with SIM800L

Using Arduino Project Guidance
1

Hello,

I want to switch a running project that communicates via BTooth to air communication, to centralize device performance and accept setup parameters on the air instead of proximity setup.

We are aware of 2G limitations of 800L, but in the short term it will be available in South America.

Our devices target Arduino Uno for small models, and ESP32 for bigger ones.

The first question is to select if going via AT commands, there are many running examples, or if use a library (TinyGSM) or the like.

Our info exchange is very little volume

Writing 6 times a day a char stream to activate a php script that inserts a record in a mySql,
Reading once a day a setup configuration char stream of 80 bytes.

Writing, in case of going via TinyGsm, can be represented as:

Thanks for your guidance !
Kind regards,

Usually Your complete current code would be needed before posting suggestions.
A short description of what You have (working) and what You aim for is helpful.

Thanks for your answer,
But I do not have GSM "current code" yet.

The code I have running is calculations codes + Bluetooth comms that will be removed.

It is like beginning a brand new GSM communications code, and then use the famous “glue technology” to add the MATH functionality I do have up and running.

Best regards,
Horacio
