Can't upload Arduino code on RAK11300


If I try to upload any code from Arduino to RAK1300, I get this :


Do I miss something ?

there’s more to the error than you have shown … any chance of showing the whole output?

Could be related to a problem that we still couldn’t fix.
The RP2040 BSP calls a batch file at the end of the installation to get some drivers installed. This requires admin rights on a Windows PC and it fails.

You can fix it by going into the installation directory of the BSP. On my computer the path is


Inside that folder is a file called post_install.bat. Open a command prompt or the power shell in this folder and run post_install.bat manually. It will ask you for permission to install some drivers, once you gave the permission and the drivers are installed, the upload should work.
