Low power with SMS Event to it wake up

Is there any sample code for sms event wake up and sample code for using UART1_R1??

here is how to use command to control RI pin:

Here is the sample code for adding callback function by le_sms_AddRxMessageHandler() to monitor SMS:

You can double check whether it will wake up to call the callback function during sleep mode.

how to check the wakeup that call the callback function during sleeping mode??

I got this error , how to fixed??

have you tried to print some logread message?
After that you can check the timestamp

see this:

root@swi-mdm9x28-wp:~# microcom /dev/ttyAT


root@swi-mdm9x28-wp:~# echo RI > /sys/class/gpio/export
root@swi-mdm9x28-wp:~# ls /sys/class/gpio/
export        gpiochip0     gpiochip1018  gpiochip884   gpiochip980
gpio2         gpiochip1     gpiochip820   gpiochip916   unexport
gpioRI        gpiochip1012  gpiochip852   gpiochip948   v2

where can i get the document about gpio from??

Which gpio are you talking about?

There shoule be a new gpioRI to control RI pin

I want to know how to setting the value?
