CC1125: The issue of transmission power debugging for the CC1125 chip

Part Number: CC1125


Good afternoon, everyone!

During the power and frequency debugging of CC1125, I encountered the following problems:
Problem 1: When I use the TI tool to configure the power and select the OOK modulation mode, if I change the power at this time, it will show a parameter error. I want to know if the power configuration is related to the modulation mode, as follows:

Question 2: When I was initializing the CC1125, I found that even though my power was set to 0db by default, the actual test on the spectrum analyzer still seemed to be around 15db. The register configuration and configuration method are as follows:

Question 3: When I was making modifications to the power and frequency, the frequency modification worked properly, but the power modification did not take effect. The method for modifying the power is as follows:

Note: The working logic of the equipment is as follows:

The above is the information and questions I can currently provide. If you have any further inquiries, please feel free to contact me. I would be glad to assist you in resolving the current issues. Thank you very much.
  • Hello!

    We have received your case and will take some time. Thank you for your patience.

  • I don't we have characterized OOK settings for CC112x. Can you check whether you're getting packets in the correct format, both for Studio and for your embedded code?

  • The tools I'm using should also be visible to you. You can open the tools yourself and test them. Additionally, under the frequency instrument, it seems that OOK is functioning. Finally, there are three issues. The most important one is the change in power. No matter how I change it, the power shown on the instrument remains the same. Please help me solve this problem. This is very important to me.
