Helloo, So my project similiar with anti lost alarm.
I want to build an alarm and connected to bluetooth (hc 05) and my smartphone (android).
So HC 05 will connected to bluetooth in smartphone, and the alarm will active when the connection lost. But i wish i could make the connection Auto connect when they are in ranges again.
((I just want my microcontroller knew when the connection got disconnect & the bluetooth will Autoconnect again.))
[u]//you know just like wifi, they will auto connect when the device in wifi area/range. #i cant use wifi since i need they disconnected in short range (5-11m) & other reasons.[/u]
