I recently faced an issue with my bolt module. Neither the green light nor the blue light is working, there is a sudden blink of the blue light. Please look forward to this issue.Thank you
Make sure your connection cable(micro USB cable) is not faulty. Check that you are providing a proper current supply to the module. Use a 5v adaptor for the better results.
I hope this will help to solve your problem.
Try connecting your Bolt module to the laptop or PC you are using, so that there is no direct supply of AC and using indirect power is safer for your module.
I have tried all methods I still cant find the solution. I guess something is wrong with the module itself.
I used my 5v adapter and still its not working.
