I am using Arduino IDE and BLE Nano to write a fairly simple beacon program for the BLE Nano. I am running a Linux computer to receive the beacon info from the Nano. My problem is that when I power up the Nano while the computer is on the LED on the Nano flashed fast for 5 seconds and goes into DFU mode. This messes up the Linux code and the computer has to be restarted to start working again.
Is there any way to make the Nano not go into the DFU mode for 5 seconds on startup?
Your assistance is much appreciated!
