Hi Community, You have a idea for this conection with Cayenne, Arduino Mega2560 like Host and ESP8266-01 like Shield (The Conection is Port Serial tx/rx), The Module is controlled for comand AT. Thank a lot!!
@pool_september welcome to cayenne community. have a look at it and follow this steps.
If you are using the ESP8266 as a Wifi shield with the AT command set installed on the ESP, and the Uno as the host, then this will not work.
@adam is talking about overwriting the flash in the ESP module itself so you don’t even need an Uno.
Connect your Uno serial port RX to TX and TX to RX on the ESP. Note that the ESP pins are 5V tolerant, but if you want to be nice, put a 1K resistor inline between the Uno TX and the ESP RX. Also note that the ESP supply must be 3.3V. If you put 5V there,…
