Hi,
I'm using the NIRSCAN Nano EVM module for a while right now.
Since a few days I'm having issues with powering the device.
I have a single cell 3.7V lithium ion battery connected. I have no thermistor connected since this battery is monitored with another safety device which also charges the battery.
Sometimes I can not power the module anymore until I've plugged in the USB power supply. Until now I have no clue when this happens and what might cause this.
After powering the module with the USB cable, the battery powering works fine again.
It seems like there is some safety thing blocking the battery? Maybe because there is no thermistor connected?
Regards,
Nick
