uz dlhsie sa trapim s komunikaciou medzi ESP8266 v AP mode. Konkretne pouzivam modul ESP01s a navrhol som si kod, kde je 1 receiver a 3 transmittery. V tejto konfiguracii (1+3) vsetko funguje. pustil som sa do upgradu a nijako sa mi nedari napisat kody pre 2 receivery (chcel by som dosiahnut 2 receivery + 1 transmitter). Vacsinou som mal problem, ze ked boli oba receivery online, tak reagoval iba jeden, no ked boli online separatne (jeden za druhym) tak reagoval kazdy z nich. Skusal som kazdemu zariadeniu nastavovat fixnu IP, davat kazde zariadenie na iny port ale bez uspechu. Naozaj som sa zasekol na jednom mieste a neviem sa pohnut. Preto by som vas poprosil, ci by ste mi s tym pomohli. Vopred dakujem
Transmitter:

}snazil som sa komentovat najviac kodu, ako to len slo, tak snad je to zrozumitelne. Mojim zamerom je, aby ked transmitter je triggernuty, tak odosle spravu do oboch receiverov a tie potom rozsvietia ledku. Kazde zariadenie ma svoju esp01s dosku a vyuzivaju svoju vlastnu wifi siet. nie je k dospozicii externa wifi.
Naozaj vopred dakujem za pomoc.
