The console has received a new feature today. The erase all checks if a module is loaded with DUELink or MicroBlocks firmware and then allows the user to completely wipe it out and reset it into DFU (Device Firmware Update).
The is a useful feature when doing a firmware update as it gives the user the option to enter DFU mode without the need for pushing any buttons. Even more useful on modules that do not have LDR button. This is what device manger will see after erase all is done.
Once erased and in DFU mode, simply go to Firmware menu option and select the desired option, nothing to physically do on the device.
