A few weeks before when I was using bolt hardware module the blue led was blinking after getting connected to the power supply. But now after some days suddenly it has stopped blinking the blue led and it has turned off so what should I do about it?
As in the starting when you have started with Bolt iot module it was showing blue light means “There is no fault on Bolt iot module”.And after some days blue led blinking off then it means that “Power supply has not given properly or your USB connector is not working properly while you have connected to Bolt iot module”.
I hope so you have understand very well.
Connect the Bolt Iot Module to the USB of the Power Bank or to the Laptop properly.Check if the blue light blinks slowly or otherwise try connecting to the other kind of USB Power Supply.
