I got some issues when I try to upload pictures by serial to the sd-card of the Nextion device using the “twfile” command.
If I run the program, there is a new file on the card created, but the type of this file is not a .jpg I want… the file is called “01.jpg.tm” which is not compatible to the ExPicture object where I want to show the picture.
Now I’m a bit confused because in the Nextion Instruction Set the “twfile” example shows excactly this usage.
twfile “sd0/0.jpg”,1120// transfer jpg over serial to sd0/0.jpg size 1120 bytes
Did I missunderstood the usage of this command or why does it not work properly?
Thanks for every reply!
