ROBOTDYN card. Mega + WiFi R3 ATmega2560 + ESP8266 (8 Mb mémoire)

bonjour,

je viens d'acquérir une carte de ce type, achetée sur internet " https://fr.aliexpress.com/item/Mega-WiFi-R3-ATmega2560-ESP8266-8Mb-memory-USB-TTL-CH340G-Compatible-for-Arduino-Mega-Nod… , " malheureusement c'est nouveau et il est impossible de trouver des exemples ou plus d'information concernant des exemples de sketch.

J'ai pu constater en faisant des test, que la partie ESP8266 fonctionne, de même que la carte Mega.

Mais je suis incapable de faire communiquer les deux ensembles, comme il semble que c'est prévu par le "Serial 3"

Pourriez vous m'aider ?

Merci par avance
Serge

Yes I will try, when i back home cus now I am outside. I want to ask you
one more question, In case we choose Generic Esp8266 Molule board, can we
still communicate and use Mega2560 pins? I need mega because my project is
need to control more than 10relays. I want send data from sensors and
storing in Firebase via Esp8266. I try many days ago to find the way to
communicate between Esp8266 and mega2560 but I still fail. Anyways thank
you again for ur helping, I will try when I back home.
