All communications are done via UART. In each example, you must specify the UART used by mainboard to communicate with ESP8266/ESP32-AT firmware. #### MEGA, SAM DUE For MEGA and SAM DUE, `Serial1` or `Serial3` will be used if you create an object (named wifi) of class ESP8266 in your code like this: ```cpp #include "ESP_AT_Lib.h" ESP8266 wifi(&Serial1); ``` The connection should be like these: |ESP8266|<--->|MEGA, SAM DUE| |:-:|:-:|:-:| |TX|<--->|RX1(D19)| |RX|<--->|TX1(D18)| |CH_PD|<--->|3.3V| |VCC|<--->|3.3V| |GND|<--->|GND| --- ### Attention The size of data from ESP8266/ESP32-AT is sometimes too big for Arduino boards, so the library can't receive the whole buffer because the size of the hardware serial buffer, defined in HardwareSerial.h, is too small. The `SERIAL_TX_BUFFER_SIZE` and `SERIAL_RX_BUFFER_SIZE` are already redefined to 256 for Mega, and 2048 for other boards ```cpp #if ( defined(ARDUINO_AVR_ADK) || defined(ARDUINO_AVR_MEGA) || defined(ARDUINO_AVR_MEGA2560) ) #if defined(SERIAL_TX_BUFFER_SIZE) #undef SERIAL_TX_BUFFER_SIZE #define SERIAL_TX_BUFFER_SIZE 256 #endif #if defined(SERIAL_RX_BUFFER_SIZE) #undef SERIAL_RX_BUFFER_SIZE #define SERIAL_RX_BUFFER_SIZE 256 #endif #else #if defined(SERIAL_TX_BUFFER_SIZE) #undef SERIAL_TX_BUFFER_SIZE #define SERIAL_TX_BUFFER_SIZE 2048 #endif #if defined(SERIAL_RX_BUFFER_SIZE) #undef SERIAL_RX_BUFFER_SIZE #define SERIAL_RX_BUFFER_SIZE 2048 #endif #endif ``` --- --- ### Examples 1.

To enable, add at the beginning of sketch ```cpp #define ESP_AT_LIB_DEBUG_OUTPUT Serial /* Comment this out to disable prints and save space */ #define _ESP_AT_LIB_LOGLEVEL_ 4 ``` --- ### Troubleshooting If you get compilation errors, more often than not, you may need to install a newer version of the board's core, `WizFi360/ESP8266/ESP32-AT shield` AT-command or this library version. Sometimes, the library will only work if you update the `WizFi360/ESP8266/ESP32-AT shield` core to the newer or older version because some function compatibility. --- --- ### Issues Submit issues to: [ESP_AT_Lib issues](https://github.com/khoih-prog/ESP_AT_Lib/issues) --- --- ### TO DO 1.
