<p class="MsoNormal" style="margin-bottom:12.0pt">Hledam MCU s integrovamou BT RF, ucelem je bateriove bezdratove cidlo s minimalni spotrebou, ktere pujde vycist treba telefonem . Narazil jsem na
<a href="http://www.ti.com/product/cc2541">http://www.ti.com/product/cc2541</a>, prvotni nadseni z x52 jadra vystridala realita. TI k tomu sice dodava nejaky BT stack, ale ten je kompatibilni pouze s IAR 8051, prictu-li k tomu nulove zkusensoti s BT jsme trochu
bezradny.<o:p></o:p></p>

data odvysilat Pricemz kvuli vode v betonu bude prvni komunikace po cca 3 tydnech a celkove by to melo vydrzet alespon 1 rok.<o:p></o:p></p>
