Install nRF52 USB to Serial Drivers
nRF52 devices typically do not require serial drivers. They use the UF2 bootloader which makes the devices appear as flash drives. Do NOT download the USB device drivers unless required to install UF2 support.
With the latest versions of MacOS, the USB Serial driver is built-in. 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
Install the CH34x Driver
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.
