Witam grupowiczów
Na wstępie musze powiedzieć, że zaczynam swoją przygodę z androidem więc proszę o wyrozumiałość
otóż mam problem z połączeniem Androida z modułem Bluetooth HC-05
chcę zrobić sterowanie oświetleniem na modułach BT
a więc do rzeczy....
chodzi i o to aby moja aplikacja podczas włączania włączyła sama moduł BlueTooth i połączyła się z jednym ze sparowanych urządzeń (któryś z modułów HC-05 lub HC-06)
część już mam
posklejane z progamów w sieci
później cały projekt bym umieścił dla potomnych
myślę, że będzie zainteresowanie.... :)
ale bez waszej pomocy niewiele zrobię ...
a oto kod
