I'm new to the whole networking part of microcontrollers and I have a question.
For a project, we have to design devices that communicate with each other.
There will be one master that sends signals and one device that receives them (for now).
We are looking into using the ESP-01 modules. If I'm correct, they can be programmed with the Arduino IDE but can function without an Arduino.
Now my question is whether I can get them to connect to each other directly, without the need of ANY other devices, like a separate network set up by a router.
Just to give you a practical example: stand outside in a field in the middle of nowhere with just two ESP modules.
If this isn't possible, could you give me any advice on how to work this out differently? The devices are on-player sports aids, so the smallest solution would be the nicest.
Anyways, thanks in advance and cheers!

Yes, just set one device into AP (access point) mode and the other into client mode.

That wouldn't work as you need at least a power source for the modules ;-).

In this case I guess your bigger problem is the power source. WiFi needs more power than Bluetooth so the later may be preferred for your project. The programming will be more difficult and you'll find much less documentation/tutorials though.
