Hi Team,

Based on the example rfPacketTRx in CCS, how can we change it to start receiving once every 15 seconds while idle time is in power-saving mode?

Hi Reed,

The example shown on that thread will leave the RX command running for 1 second, and then timeout.

Arthur

Hi Arthur,

Thank you for your feedback.

The code makes rx timeout after 10 seconds. How to re-trigger rx function after 15 seconds?

After above timeout, the current still very large (EnergyTrace shows about 7mA).

How to make it go to sleep?

Hi Reed,

You can do it in several ways:

The rfcore automatically can re-trigger the command 15 seconds after the previous one using the TRIG_REL_PREVEND start trigger type:

I do not recommend that way because the rfcore will not sleep, and then probably use around 1-2mA of current in the process.
Use the application processor. After RF_runCmd(RF_post) is done with the RX command, you can call RF_close, and then call the sleep/Task_sleep functions, which will let the Power driver now that you want to go into standby mode.
Beware that the device cannot go into standby if a debug session is running.

Regards,

Arthur
