deep sleep wake up cause is not tue
Posted: Tue Apr 24, 2018 7:15 pm
The code at the end of this post working perfect. It gives the exact wake up reason when it wakes up from deep sleep. For power consumption efficiency I want to close the peripherals with a GPIO pin ( pin 4) connected to a MOSFET circuit . So I decided to add a
statement before going to sleep . After wake up I add the following statements to the starting off the program.
after adding these statements the wake up reason becomes undefined. What will be the possible cause of this behavior?
Code: Select all
mgos_gpio_write(4,0); Code: Select all
mgos_gpio_set_mode(4, MGOS_GPIO_MODE_OUTPUT);
mgos_gpio_write(4,1);Code: Select all
