Bolt worked for some days but now it just does a flash when connected to power supply and nothing else. Does my Bolt died ? Is there anyone else with the same problem ?
It may caused due to loose connection, try switching on it by providing power supply externally using arduino uno or any another source,
arduino 5v pin - bolt unit 5v pin
arduino GND pin - bolt unit GND pin
Thanks for your quick response
Indeed i’ve tried to power the bolt using the 3.3v and GND pins using an external power supply and it worked !
So it means that the USB power supply of the Bolt unfortunately died
Have to experiment with an Arduino/STM32 attached to it now
Thanks again for your response, it solved my problem
