The driver didn't come with any sort of testing program, so I installed USB Blaster.

Shelved it and was working on testing a repaired usb joystick. Install CP2102 driver from Silicon Laboratories. Looked at the amazon page, and realized i don't have the ch340 UART. Tried resetting while holding the flash button. 'New version' according to Amazon) I struggled with this for a couple of days trying to get my macbook (Mojave 10.14.3) to just see the thing. Take a closer look at your nodemcu board and make sure which one it is, if it says SILABS CP2102 (very small on top of one of the chips) then follow these instructions from knohbodyįinally got my ESP8266 (Nodemcu. Thank you knohbody for sharing your solution, this was what worked for me.

I think the problem for some of us is the Arduino IDE. Is there anybody else who has experienced this strange behaviour using the CH34 package and the arduino nano? this was really frustrating because I don’t have any idea why it started to work again/ stopt working.

I can vaguely remember having the same issue on an older os that also out of nowhere just seemed to work again a few hours later. just a few hours later it disappeared again without doing anything strange with my macbook… Soo my arduino was running fine again without any problem. Now the strange thing is that after giving up after numerous attempts to get this thing to work an hour later when i turned my macbook back on the right port “magically” appeared again… So I tried to do the logical thing, reinstalling & deleting the old drivers etc. I also updated to mojave but at first my arduino nano had no problem finding the right port to upload to, but today all of the sudden the port disappeared from my options menu. Hey everybody, I have been having the exact same issues as the rest of you.īut I did notice some strange behaviour with my arduino serial port that I didn’t see anybody commenting on yet.
