#86770 Hi,
I'm new in the world of ESP8266 and Arduino. For my project, I want to configure the ESP8266 so that it can transmit data without connecting with any existing wifi network. I wanna use one or two ESPs. For my project, I don't have any worry of receiving data, just want to generate traffic from one ESP8266.
I am trying this project with ESP8266 NodeMCU ESP-12E and Arduino Uno.
So, my goal is:
1. Generating wifi traffic (not any sensor readings).
2. Controlling transmission rate
3. Changing wifi channel as we can change in router
Is these possible with ESP8266 NodeMCU and Arduino? Can you provide me any guidelines and or coding?

#86823 The ESP has libraries for doing ESP to ESP comms that without you having to write anything - have a look at ESPNow. This is something that's available in the NonOS SDK but looks like they've made a library for it for Arduino too.
