I am trying to get it to wake up when the CTS line is enabled to prevent this. Currently I have done the following: defined CFG_EXTERNAL_WAKEUP in da1458x_config_advanced.h so EXT_WAKEUP is defined as 1
defined EXTERNAL_WAKEUP_GPIO_PORT as the UART1 CTS port, EXTERNAL_WAKEUP_GPIO_PIN as the UART1 CTS pin, and EXTERNAL_WAKEUP_GPIO_POLARITY as 0 in user_periph_setup.h
configured the wakeup pins in set_pad_functions() in user_periph_setup.c with: GPIO_ConfigurePin(EXTERNAL_WAKEUP_GPIO_PORT, EXTERNAL_WAKEUP_GPIO_PIN, INPUT_PULLUP, PID_GPIO, false);
Is there anything I am missing? Is there a different way to solve this issue?
