<p style="margin:0in;margin-bottom:.0001pt">Taketo riesenie sme pred par rokmi navrhli<br>
avsak realne do praxe nikdy nenasadili.<br>
Bolo to v zlozeni:<br>
BT modul + ATMEL, HUB Pro od Olympa a obsluzny sw.<br>
Problemom bolo ako obmedzit komunikaciu BT modulu<br>
len na urcity fyzicky priestor. Pretoze sa stavalo, ze system<br>
zareagoval a otvoril dvere, hoci bol uzivatel o poschodie vyssie.<br>
Inak to funguje dodnes ako demo prezentacia.<br>
Takze urcite by to slo aj s BT + PIC + rele.<br>

Zdravim,<br>
nema nekdo zkusenost at uz s hotovym resenim nebo nejakym projektem (nejlepe pro PIC) na pristupvy system (tj. jen sepnuti rele pro zamek) reagujicim na pouhe priblizeni mobilu se zapnutym BT (bez nutnosti zadavat PIN) ?<br>
Nasel jsem jen dve ceske firmy ktere toto nabizi,ale zadna nepise cenu a na maily bud nereaguji nebo vyzaduji registraci<br>
a ICO a pak se pry uvidi, jestli uzna jejich obchodnik za vhodne se vubec bavit...<br>
