현재 인증이나 기타 문제로 인해 Android 보드에 WIZFI250을 사용 예정에 있습니다.
H/W는 이미 설계를 끝냈고 S/W 적인 요청 사항이 있어 문의 드립니다.
Android 에 AT command script 를 포팅 할 수 있는 가이드 문서가 별도로 있는지요.
확인 부탁 드립니다.
감사합니다.
별도의 안드로이드용 소스는 없습니다만, 범용적으로 참고할만한 Host Demo 소스는 있습니다.
아래는 WizFi250를 제어하는 (Dos용) 예제 소스입니다.
몇몇 부분을 수정하시면 안드로이드 및 다른 플랫폼에서도 사용하실 수 있을 것으로 생각됩니다.
참고하시기 바랍니다.
