I have a brand new Wio 2G tracker. I tried to flash a sketch on it but had the wrong board type selected by accident.
Now it just has the orange “rx” led flashing repeatedly, and I can’t upload anything to it.
Even when I press reset twice it goes back to the rx LED flashing…
How can I restore this unit?
By the way, this is the output when I try to flash a sketch.
This same environment works fine with another Wio Tracker I have

Please try to press the reset button quickly and you will see RX led(near MCU) blinking quickly. it will enter into download mode. Then check the device manager. If you see the COM port, it shall work for the programming.
Please do make sure follow
