<p>Zdravim, asi obejiti by bylo zakazat prepnuti do druheho vlakna
nebo preruseni vubec. Ono to nejspis spadne jinde ne ve Vasem
kodu, kde se pouziva cache. To je dobry tak pro zapis jednorazove
konfigurace. Jinak zakazani preruseni, dalsich vlaken znamena, ze
Wifi, stack TCP nebude vedet co se deje a pozada o opakovani
packetu,... , zvladne to, ale ... . To bych radeji zapisoval do
FLASH vedle, ktera je na modulu pres SPI.<br>
