I have uploaded a few programs to my ble nano v2 and each time I upload a program the on-board led flashes constantly and it wont stop. From the moment I apply power the led keeps flashing. Also, when the led does stop flashing the code runs just fine, but I can’t seem to figure out what makes it stop. Side note it shows up as DfuTarg on my devices. Also, I am very new to these boards and BLE.
What is your Arduino IDE version?
Also, please provide the compilation and uploading log for evaluation.
