CCS/LAUNCHXL-CC1350: DYNAMIC SMART RF SETTING

Some details are missing in your post. I'll make an assumption that you use "rfEasyLinkNp AT Network Processor Example" and the API commands described here here: processors.wiki.ti.com/.../SimpleLink-EasyLink

If you are in TX the frequency will not change if you just send a new ATPFR with a new frequency. If you look at the easylink examples in the SDK you will see which order the commands has to be done in.

Hi, a secure way of implenting frequency change is to do a RF_close / RF_open with the new parameters .

For changing phy's, overrides, centerfreq. etc.. it is sufficiant to use RF_control (xx,RF_CTRL_UPDATE_SETUP_CMD,xx) without RF_close, RF_open. The new setup will take effect in the immediate next power cycle of the radio core.

i am using rfpackettx_433. i am sending a data from uart(docklight) that conatains frequency change flag and new frequency where i have to change. i read it from uart and assigned to concerned bit field. its bitfield got modified but its still transmitting at older frequency.

Hi FredG, I am very new to code composer studio. Can u please elaborate your second paragraph. I am not getting how to use RF_control API. Thankuuu

I would recommend you to look through the SDK documnetation: dev.ti.com/.../index.html

This also contain information about the RF commands and how to use them. Also see the examples in the SDK.

Hiii, in the RF_control 3RD parameter is void *args. How will i write if i want to update RF_cmdFs.frequency to new value which is stored in newfrequency variable. thankuuu

Hi, since your experience with the driver is limited, I would go for the RF_close, update RF Parameters, RF_open solution.
You can find the correct settings in SmartRF Studio, and check out this training which shows how to import and use settings from SmartRF Studio to CCS:

Hi FredG, thanks for acknowledging. i have to change smart rf settings via code. my updated settings is not being updated. i followed the way what u told.if possible please help me regarding RF_control API that u mentioned in previous post.

Hmm, if RF_open / close dont work Control wont work either. What is the original freq and what is the new freq?

By the way, check the PER example as it changes phy's and frequencies on the fly based on uart communication. I cannot show you any links as i am accessing this site from my mobile right now.

sir, thanks for acknowledging again again. Currently i fixed 433.9200 MHz in smart rf setting. Now i want to go 436.1200 MHz. i have given frequency change command and frequency value from docklight . I read the value of frequency in my code and store it in variable termed newfrequency . Now in the RF_control API 3RD parameter is void *args. How will i write if i want to update RF_cmdFs.frequency to new value which is stored in newfrequency variable. Please tell me what should i write as 3Rd parameter. i m very very thankful to u.

Hii, i checked via breakpoints . i am stucking at RF_close. this is not being executed. first i am doing rf close then reading data from uart and RF_open.
