CC2530: power control

Make sure that you have the correct HAL_PA_LNA_CC259x macro defined so that proper power tables are used accordingly.

Thank you sir...

I also want to know how can I figure out the default value that is defined for tx power and where can I find it???

And is it possible to set tx power to any arbitrary value or it is based on some specific standards???

Thank you so much 

Tnx sir,

Which of the macRadioDefsTxPwrTables is for CC2530PA1?

I became confused after reading these links.

Can you summarize what steps should I take to change the power in this module?

thankful

Can you post schematic of your module?

RL-CC2530-PA1 English V1.1.pdf

thank you :)

excuse me sir
Why can not the maximum output power be 23 dbm? It is written in datasheet 23 dbm

According to my experiences, it will be over saturated and you might not pass any RF regulation with such large TX power.

thank you

I've made the changes you mentioned above, but the transmit distance of this module is 2 meters :( please help me

What  TX power do you set?

 i set it to 20 dBm...

Try to set it to 16dbm to test again.

i did the test as you said but the result was the same and the maximum distance was about 2 meter. any idea???

I would suggest you to use SmartRF Studio to do PER test first.

What is this test? can you explain more?

hello

I heard about some kind of PA circuit in CC2530 module which should be enabled by setting a pins value, and did some search on it and found this peace of code in mac_radio_defs file:

/* P1_1 -> PAEN */
RFC_OBS_CTRL0 = RFC_OBS_CTRL_PA_PD_INV;
OBSSEL1 = OBSSEL_OBS_CTRL0;

how should I adjust the PA to maximize the transmit power? is this effective?

I have told you to use “macRadioSetTxPower(16dbm) ;” in your application init function to set TX power to 16 dbm. You can change it up to 20 dbm.

We've already discussed how you have to change the Z-Stack P1.1/P1.4 settings for the SkyWorks RFX2401C PA.  https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/158/p/812151/3009091#3009091

The CC2530-PA1 datasheet provided already recommends the mac_radio_defs.c pin settings you've described.

yeah and as you said I did that and put the power equal to 20dbm and also I defined the HAL_PA_LNA in project options and changed the mac_radio_defs.c as above, but the range is too short about 20 meter...

This appears to be a hardware issue, you should contact the board manufacturer or use a TI EVM.

thanks Ryan for your help,

I saw the previous links you had sent to me and in one of them it mentioned that I should check the pins to make sure whether they toggle or not. so besides  the above things I have done, I called these functions in my application event loop to set my transmit power and put break points before them:

macRadioTurnOnPower()

macRadioSetTxPower(20)

by testing, I saw that it toggles on macRadioTurnOnPower() but it doesn't enter the function to see the pins state.

I don't have scope to check by. is there any solution to check the pins state on any transmission?

I suggest you to use scope check if your PA and LNA pins work when device does TX and RX.

excuse me sir
  Which one of these two is my module's power amplifier?(CC2591 or CC2592)

When doing TX, you should see TXEN goes high. When doing RX, you should see EXEN goes high.

But my question was this:

 Regarding the above image Which one of these(CC2591 or CC2592) is my module's power amplifier?

I remember you mentioned you use rfx2401c, don’t you? Why do you ask CC2591/CC2592?

I didn't mentioned that,  but actually it is true and my cc2530pa1 includes an rfx2401c range extender, but according to your previous suggestions "which was about defining HAL_PA_LNA_CC2591 in project options" , I guessed that I should define HAL_PA_LNA_CC2591 in my project options. But now I doubted between cc2591 and cc2592 because of the following part of datasheet.

I remember I give you suggestion according to your schematic.
