nRF52 Serial Drivers
Install nRF52 USB to Serial Drivers
With the latest versions of MacOS, the USB Serial driver is built-in. Do NOT download the USB device drivers unless required. If you downloaded/installed any already, please remove them.
Remove the CH34x USB Driver (macOS)
If you have already downloaded/installed the macOS WCH-IC CH340/CH341 ("CH341SER_MAC") drivers via the CH34x_Install_V1.5.pkg, you will have to Uninstall the kernel extension:
- Unplug your device
- Open the Terminal and run:
sudo rm -rf /Library/Extensions/usbserial.kext
After installing the driver, make sure to reboot your computer to finish the installation process.
You can also test your serial driver installation at this step if required.
After installing the serial drivers, you can now flash the Meshtastic firmware onto your device. To proceed, select the appropriate device type for your device.
