I’m struggling with connecting my ESP-12S & Arduino Mega to Cayenne. Being complete beginner in Arduino I made a progress with many youtube movies and spending days on forums. It brought me to the point where ESP can connect to my WiFi and I’m able to connect Arduino via USB connection to Cayenne. What I cannot do is to connect Arduino to Cayenne via ESP.
I’m using this wiring: https://cdn.instructables.com/F3W/ON46/IYKG2WG9/F3WON46IYKG2WG9.MEDIUM.jpg?width=614
When I have connection between RST and GROUND on Arduino (green wire on diagram) I’m able to connect to WiFi with ESP but not being able to upload Cayenne code for Arduino Mega with WiFi Shield. ArduinoIDE is showing:
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
An error occurred while uploading the sketch
When I take out this connection, I’m able to upload the code but in Serial Monitor see info that “ WiFi shield not present”. Managed with success to connect Arduino via USB to Cayenne but this WiFi connection irritates me.
Is someone seeing where I’m making mistakes?
