Port com

-

i wrote first program , except can't program recognize port com. stays grayed out. have spent several hours on  , asking fresh leads. i've gone through  several tutorials , gone through quite few of posts. i  think part of problem learning language arduino speak. have found port (0003) in operating system (no easy task in windows 8), along hub number 0007. can't seem board recognize them. think need new cable? mine pretty old.

what arduino board using? version of ide? arduino com port connection being recognised pc has nothing program you're trying load.

i think you're saying have ide open, arduino plugged usb port on pc when try select port using tools/port greyed out. if that's correct it's worth trying different usb cable. may worth trying plugging different usb port on pc - in particular make sure it's usb2.0 port because faster usb3.0 ports can cause problems.

esp8266 (nodemcu 0.9) client.write très lent ???

bonjour à tous, j'essaie d'établir une communication entre une carte nodemcu exp8266 et mon pc en wifi via les sockets wifi. cela fonctionne plutôt bien mais le problème vient de la lenteur des instructions liés à l'écriture : par exemple client.write(buf) qui s'exécute en 200ms et est donc bloquante. comment peut on faire pour réduire ce temps d'écriture car c'est vraiment handicapant. merci a+ antoconde vous êtes sous windows? si oui c'est sans doute dû aux delayed acks quote if make network trace network sniffer such microsoft network monitor, tcp server sends tcp ack segment last tcp segment in tcp data stream in delayed acknowledgement timer (also known delayed ack timer). default, windows operating systems, value timer 200 milliseconds (ms). faut éventuellement gérer l'agrégagtion d'ack dans votre code pc en contournant les infos systèmes. ça améliorera un peu les choses - mais le problème est côté pc pas esp (pa
