CC2340R5: Time to first message

Part Number: CC2340R5

Hello,

We want to use the CC2340 in a simple IoT application.

Do you have measurements on how long it takes from powering on the CC2340 until a simple message to a previously paired device is sent?

Thank you and best regards,

Ambroise

    Hi Ambroise,

    This will greatly depend on the custom application that the user has implemented as well as any setup/initialization that the user may want to do (SPI, I2C, UART, etc). This will also depend on how the device is connection to the peer as well as the advertising/scanning parameters used. A value for this can be found experimentally by using a logic analyzer and toggling a GPIO when the connection establishment event is posted to the program.

    Best Regards,
