Mikroswitch Sw1 służy do przełączania trybu pracy modułu, w tym wprowadzania w tryb AT. Zalecanym sposobem
Micro switch Sw1 is used for module work mode switching, including entering in AT mode. Recommended method of switching module in AT mode is to push and hold Sw1 before power supply enabled (interface UART works therefore with speed 38400 b/s). Module signalizes entering in this mode by LED D1 blinking with frequency 1 Hz. High state on KEY output of module can be forced from microcontroller program (PA0/A0). If LED D1 is blinking with frequency 2 Hz, that means waiting for pairing or completing of pairing process. Ending of pairing process is additional signalized by enabled LED D2.
przełączenia modułu w tryb AT jest wciśnięcie i przytrzymanie Sw1 przed włączeniem zasilania (interfejs UART pracuje
wtedy z prędkością 38400 b/s). Moduł sygnalizuje wejście w ten tryb pracy miganiem LED D1 z częstotliwością
1 Hz. Wysoki stan na wejściu KEY modułu można wymusić także z poziomu mikrokontrolera (PA0/A0).
Jeżeli LED D1 miga z częstotliwością 2 Hz oznacza to oczekiwanie na sparowanie lub poprawne sparowanie, które
dodatkowo jest sygnalizowane za pomocą świecenia LED D2.
