Sorry for the noob question.

I have my sketch all running fine when bluno is plugged into my mac USB. However when I unplug and plug the USB into a USB charger my sketch does not work anymore. The green ON light is still on, even the TX and LINK line is on showing incoming data but my sketch does not seems to run.

Anyone can shed some idea? How do I run my sketch without being plugged into a computer?

Thanks

How is going?

It should be ok with external power supply( Voltage 5-12V). what is your charger like?
