RTOS/CC1310: RTOS/CC1310: Wake up from STANDBY via UART issue

Part Number: CC1310
Other Parts Discussed in Thread: SIMPLICITI

Tool/software: TI-RTOS

I have a question about the cc1310.

I saw the thread below.

In my project, a particular mcu will send data to the cc1310 via uart.  (The examples used in the project as base are rfWsnNode / rfWsnConcentrator.)

I know that the default power policy of the cc1310 is in standby mode.

That's why I think the cc1310 will enter standby mode during the time that data is not passed to the uart.

However, I know that in standby mode it does not wake up when it receives data through uart. (I referenced the thread above.)

How do I set the cc1310 to wake up with a uart interrupt?  (ex ) power mode setting or uart driver setting)

Thank you.

    Hi Kim,

    There is no way to configure the device to wake up from standby on UART interrupt.

    What you can do is to implement your own "Wake on UART" functionality by configuring the RX pin as normal GPIO with interrupt enabled. Then when you get the PIN interrupt, release the pin from the PIN driver, open up the UART and perform a read.

    You could use the SPI example for this as an example for how this can be done, look at the "Wake Up on Chip Select ..." section:
