<div>vcera jsem prohlizel dokumentaci knihovny Wifi pro ESP a
nejak v ni nevidim jak nejak jednoduse zjistit na jakych IP
sedi klienti do AP prihlaseni.</div>
<div><br>
</div>
<div>Je tam metoda jak zjistit jejich pocet, ale ne kde
jsou...aspon to nevidim. A take jsem zatim nenasel jakym
zpusobem AP v ESP prideluje IP adresy klientum.</div>
<div><br>
</div>
<div>Libilo by se mi, kdybych cas od casu mohl vylistovat seznam
klientu, abych jej mohl porovnat s aktualnim stavem a ty co
pribyly mohl zacit vycitat.</div>
<div><br>
</div>
<div>Takhle by mi nezbylo nez projizdet celej subnet a zkouset
zda se neco ozve</div>

<p>A v čem to programujete? Jedná se o ESP8266 nebo 32? U 8266 nevím
jestli používá LWIP, pokud ano, mělo by to jít zjistit přes
rozhraní této knihovny.<br>
