Hello everyone,
I have a general query about any embedded system. Whenever we use any communication device(maybe Bluetooth or WiFi or GSM), is it advised to use AT commands to control the device?
Thank you in advance.
Regards
Sarthak

AT command provide a familiar method to configure/control modem type devices, you can do things differently, but then you have to sell/support that idea in your product.
Modems are typically configured using AT commands and then switch to a data mode as is more efficient.
If you are building a self-contained device, say LoRa or sub-ghz radio, where all the software lives on the same micro-controller, you can dispense with the AT commands and program directly with the radio/comms stack or API.

You have to use whatever interface the device provides!
- If that is only AT Commands, then you have to use AT Commands.
- If the device does not support AT Commands, then you cannot
use AT Commands.
If the devices supports both AT Commands and some other thing, then you would have to evaluate the pros & cons of each.
A complex system designed from scratch never works and cannot be patched up to make it work.
