Debug

To enable SWD debug and get debug message through USB Virtual serial, please install the driver. To use Keil or IAR, just export your program from online IDE

Energy Monitoring

Changing the baud rate of the USB virtual serial port to 4000000+ will trigger current measurement. We designed a tool - Tiny BLE MONITOR for you to get the power consumption information easily.
