GM862 Evaluation Board
Модуль Bluetooth для Arduino
Модуль Bluetooth производства Libelium даёт возможность взаимодействовать с другими устройствами по протоколу bluetooth 2.0. Плата выполнена в том же форм-факторе, что и модуль XBee, что даёт возможность устанавливать её точно так же, в гнездо на IO Shield или Mega IO Shield.
Мощности передатчика хватает для работы на расстоянии до 40 метров в помещении и до 60 метров при прямой видимости.
Общение с bluetooth-модулем ведётся по serial-соединению, через набор AT команд.
Подробнее об использовании и программировании модуля можно прочитать на сайте производителя.
