Howdy,
To achieve the lowest possible power consumption on the nrf9160, it is noted that it is necessary to disable the UARTs that are not used, when in sleep mode.
However, when the UART is in this disable mode, is it possible to configure the UART so that the reception of a character on the UART's RX line would "wakeup" the nrf9160 from it's low power sleep? If that is not possible, what is the recommendation? Configuring the pin as a GPIO to detect a transition on RX, waking up, and then re-configuring the pin as a UART?
Using Zephyr OS, is there a software hook that needs to be hooked so that custom low power actions needed to achieve the low power state are executed on the way into and out of low power?
V/R,
