Dear all,
I have a problem. Used Third party sim card. when I run “particle flash --serial firmware.bin”
That can’t connect with my computer. Could you please help me to solve this problem. please.
I assume your device is connected to your computer, is in listening mode and had the serial drivers installed?
I’d rather go with DFU mode and
particle flash --usb firmware.bin
For that you might need to install dfu-util, if you haven’t got it already (e.g. by using the CLI installer for Windows).
I install " dfu-util 0.8 " already
and try install “usb firmware” this image, I’m not sure flash success.right? Could you suggest me please.
That final
Flash success!
Does suggest … well … success
