Wio LTE Cat.NB-IoT(SARA-N410) v1.0 Bricked?

I attempted to copy some of the example code to my device and now I don't get any response from it when it is plugged in. Prior to sending it code, from the Arduino IDE, the STA light came on blue. Now that light does not come on at all. It also no longer shows up as a USB device on my Mac.

With the USB and battery connected I only get the CHG light on. Double pressing the RST button doesn't produce any different results. Not sure if there is a timing issue around double pressing that though.

Open to any suggestions/tips/tricks on how to get this board back among the living.

Thanks,
Ken

Hi Ken

1. the STA is orange led and NET is blue led.

2. please follow below instruction to burn the code to control onboard rgb led. you have to press the boot button on the back side of board and then plug the usb cable. there will be no COM port on arduino ide. but you can download the code. After that, you have to press the reset button one time. then you can see the serial com port. thanks.
