MSP430 + boosterpack sigfox, Send to sleep cc1120

Other Parts Discussed in Thread: MSP430F5529, CC1120

Hello,

I'm using the demo project that provided me sigfox, and I am developing an application using the network of sigfox by the MSP430F5529 + boosterpack. So far I have set the MSP430 in low power consumption (LMP3), now I want to send to sleep the CC1120 module of the boosterpack by SPI.

How can I do this?

In what part of the code (TI_SIGFOX_FCC_ccs_project) I can set the SPI?

Do you have an example code where you do this?

Hello user4069902,

Please refer to the section "3.2.2 Command Strobes" of CC1120 users guide www.ti.com.cn/.../swru295e.pdf for information on how you can achieve this. You can use trxSpiCmdStrobe(CC112X_SPWD) in your code to enter power down mode.

You can download - CC112x Software Examples (Rev. E) from www.ti.com/.../toolssoftware to see how this can be used.

You can consider putting CC1120 to sleep after a Tx is done if you do not wish to receive any down-link messages. This will be in host_cmd.c

Regards,
Prashanth

There is no use of trxSpiCmdStrobe(CC112X_SPWD) or a file named host_cmd.c in the Software examples Rev E.
