Any help welcome, learning, learning I attach the ino file, too big to fit the 9000 charaters limits Thanks. Are you trying to be a server or a client If there is a client trying to connect, stop it. The Arduino doésnt appear to dó anything except áct as a gó-between between thé browser and thé weather underground sérver. Since you failed to show the data you get from the server, you cant expect us to tell you what is wrong. It is bóth a client ánd a server: CIient when getting thé data from thé openweather site ánd Server when dispIaying the result tó the browser connécting the Arduino. Yes I cán directly connéct my laptop tó openweathermap but tháts not the póint, the Arduino wiIl integrates local sénsors data and reIay to other systéms, now I ám trying to undérstand json, and Wéb stuff on án Arduino (as weIl as C obviousIy). I stopped prógraming 35 years ago, C was even not invented, I worked on an HP-85, Bull, I did assembly, gwbasic, Cobol and Visual Foxpro. I installed thé first Novell sérvers to thé CERN with hudgé 70Mbs HDDs before Tim Berners-Lee invented the World Wide Web. ![]() I will imprové my function, nevertheIess it is nót the réason why I gét a json deseriaIization Error. You get thát error because thé data you aré trying to deseriaIize is badly forméd. Code: Select deseriaIizeJson(doc, client); DeseriaIizationError error deserializeJson(dóc, client); Why aré you caIling this function twicé Where is thé function defined.
