Unable to upgrade firmware to 0.3.1 on Red Bear Duo board


I am trying to upgrade the firmware from 0.3.0 to 0.3.1 on red Bear Duo board using the dfu-util the commands correctly executed but the firmware didn’t get updated as seen in the following image.particle-cli2

Can any body help that how to sort it ?




Hi Naveed,

Please first make the Duo enter listening mode and check the system firmware version using serial terminal: https://github.com/redbear/Duo/blob/master/docs/out_of_box_experience.md#using-serial-terminal.
