I designed a mainboard for bcm20732s module which provide VCC and GND for 20732s.
I could download application, like hello_sensor, into 20732s, but after running, trace info like this, why battery level is critical? If battery is low, why download process is ok? SMART SDK is 1.1.0.
GPIO_WP:OFF=0

In your database_init function, your program probably calls blebat_init(). This function actually comprises of four functions (dbinit, config, startmonitoring, pollmonitor), all which are loaded in ROM.
If you want just the message to go away, you can just comment out startmonitoring and pollmonitor.

furthermore, if I use SMART SDK V1.0.1, hello_sensor can run and hello_sensor_timeout occur every one sec even if "Battery level is critical, Shutting down" appear.
Why this phenomenon?

mochi,
I have commented out startmonitoring and pollmonitor in v1.1.0, but hello_sensor is still shut down. callback hello_sensor_timeout() isn't invoked periodically which mean that MCU is power off, so startmonitoring and pollmonitor is not key point, I don't care whether the message is disappeared, I want the application running actually.
In v1.0.1, I don't comment out startmonitoring and pollmonitor, hello_sensor application is still running even if the message appear.

Not sure this is the issue, but worth checking of course.
Note that the battery critical message will come up when the GPIO configured for Vbat measurement is not connected to Vbat.
All sample apps use P15 for this function (and the tag board has it this way as well).
