Force upload program

Hi

How do I force upload a new program - if serial port has been disabled or application crashed? - when running the GPStracker I have 30 sec. to upload a new program, and is not too handy

Thanks
Felix

Dear Felix,

Connect the reset pin 2x fast to ground and it will go into bootloader mode. You will see another com port at your pc.
