During the upload to the Nextion device I cancelled the upload because it took about 70000 seconds and normally it takes around 150 seconds (For my program). So the setup all did work but because I cancelled the upload the Nextion isn't responding anymore.
When I power the Nextion device now, the screen stays black and the upload will not work (Connection fail). Is there a solution for this problem? Programming with SD card? Or firmware for MCU?
Try upload by SD card?
Ok, I hadn't had one in spare so I ordered a new one. Hope it will arive today. Then I'll get back to this topic.
Received the SD card and the problem is fixed!
