Seems to enter green flashing light via double clicking back button, does no show on Windows pc, tried two different cables, different usb ports. Nothing will get it into dfu mode or to be recognized on the pc???
might a factory reset via Meshcore software help??
have a second Wismesh flashed to Meshtastic and it goes into dfu mode no problem on same pc…
Based on your description, the issue is isolated to one specific WisMesh Tag unit. Since your other WisMesh device enters DFU mode correctly on the same PC, the problem is likely with that particular unit’s hardware or its bootloader.
A factory reset via the Meshtastic/Meshcore software will not help if the device’s USB bootloader is corrupted or if there is a physical USB connection fault.
