Topic: WiFi communication between two ESP8266 and phone using RemoteXY

Is there a way to implement such a project?
I've tried ESP-NOW between modules, following the wifi library examples and all sorts of other things.
Every time there's some kind of conflict between the libraries. Either RemoteXY crashes or the communication between the two ESP8266s gets stuck.

Re: WiFi communication between two ESP8266 and phone using RemoteXY

From OpenAI:
ESP8266 can use ESP-NOW together with Wi-Fi, but with limitations

  • STA (Wi-Fi client) + ESP-NOW — possible, but:
    The ESP8266 must be connected to a Wi-Fi network on the same channel as ESP-NOW.
    If the router changes its channel, ESP-NOW will stop working.

  • AP (access point) + ESP-NOW — possible, but:
    Devices communicating via ESP-NOW must use the AP’s channel.
    Broadcast transmission may be unstable.

  • AP+STA (dual mode) + ESP-NOW — not recommended:
    ESP8266 has limited memory.
    Often leads to unstable operation.

Main differences from ESP32

  • ESP8266 has a single RF module, so ESP-NOW and Wi-Fi must be on the same channel.

  • ESP32 has two Wi-Fi interfaces (STA/AP) and can switch dynamically, so ESP-NOW + Wi-Fi is more stable there.
