Jestli tohle nemuze zpusobit nejaky IO block (pomala SD karta ???)

No kazdopadne mi ty dva requesty po sobe delaji problemy s mojim hackem IoTgetImage(url) v prepare_image() => posle 2x PendingInfo paket se stejnym imgUpdateVer = imgVer
Takze to zatim ohybam pres timestamp

No nie je to uplne optimalne navrhnute, priznavam, station uz by mal vediet aky obrazok posle este pred tym ako pride request, je tam iba 100ms na odpoved a niektore systemy to nemusia stihat.
