Hello:
In the past 3 months, we have purchased 20 Aduino Uno R3 units from RobotShop. When trying to upload Arduino Sketches to these boards, the upload fails. The error message is: “Problem uploading to board”. All of the Arduino Uno R3 units are authentic Arduino products (no clones or knock-offs). Here is a listing of what I’ve already performed prior to this email to you:
-
I have used other Arduion Uno R3 boards (purchased last year) and there are no problems uploading sketches.
-
The latest Arduino IDE (Ver 1.8.5) was downloaded and used to ensure compatability. The older Arduino Uno boards have no problems uploading sketches with the 1.8.5 IDE.
-
When testing the uploading of software, I tried it on numerous Arduino Uno boards that have been purchased within the last 90 days to ensure that the problem was not localized to only one board. All of the Arduino Uno’s in the latest purchases have problems uploading to the board.
-
All of the Arduino Uno with uploading issues have had no problem with the computer assigning USB COM Port numbers. So, the computer “sees” the Arduino Uno’s.
Within the next week, I have an Arduino class that I’ll be teaching and need these units to be operational ASAP.
Thank you!
