Wio-Terminal/ESP8622/ESP32ボードを共通のスケッチで動かす(REST-API編)」で、Wio-Terminalのスケッチが動作しなかったので、その代わりのスケッチを提供する。 (ホストPCとしてはubuntuを想定している)

以下の#defineでボードを切り換えているがボードの種類を設定すると、 システムで設定されている定義が有効になるので特にソースを変更する必要はない。

#define WIO_TERMINAL #define ESP8266 #define ESP32


const char ssid[] = "yours_ssid"; const char pass[] = "yours_passwd";

書き込み後に「picocom /dev/ttyACM0 -b115200」または「picocom /dev/ttyUSB0 -b115200」で通信ソフトを起動すると以下のような出力が表示される:
