Hello,

I am trying to communicate with CC2510 using proprietary RF mode. I was successful in doing this using CC2650-LAUNCHPAD with the following settings in the smartrf_settings.c. So, I tried the same on our custom board which is based on CC2650EM-5XD-RD MCU but was unable to transfer any data.

// TI-RTOS RF Mode Object
RF_Mode RF_prop =

.rfMode = RF_MODE_PROPRIETARY_2_4,
.cpePatchFxn = &rf_patch_cpe_genfsk,
.mcePatchFxn = &rf_patch_mce_genfsk,
.rfePatchFxn = &rf_patch_rfe_genfsk,
};

I am not able to figure out the issue. Can anyone please help?

What have you done to verify that your custom board work as wanted?

Follow as a guide to what you should check.

I didn't get your point exactly, We have taken care of the things which are mentioned in the attached document by you. I have managed to communicate with CC2510 using a launchpad but Launchpad has a different variant of CC2650 as compared to our MCU. So I guess, we need to change some hardware-specific values?

But I have no idea how to that.

Have you done some tests using SmartRF Studio?

0 Rahul Gusai over 4 years ago in reply to TER

I replaced the overrides array in my smartrf_settings.c with the ones exported by the smartRF studio but had no luck. Are there any other tests that I should be doing?
I would like to add one more thing that the custom board is able to communicate any other CC2650 radio. So, the problem is only there in case of communication with CC2510.

Have you done some tests using SmartRF Studio? (Use Studio to control your board)

0 Rahul Gusai over 4 years ago in reply to TER

Intellectual 260 points

Yes, I have controlled my board using a smart RF studio, it works. Also, I am able to communicate with a CC2531 sniffer using the custom board. The only difference between the RF designs is that in Launchpad, it is externally biased whereas, in the custom board, it is internally biased and differentiated mode.

We want to communicate with the CC2510 radio in proprietary mode RF as our receiver is also configured for the same.

TI__Guru**** 317180 points

Meaning that the settings you use in the code is the same settings you use in SmartRF Studio when you control your board with SmartRF Studio?

0 Rahul Gusai over 4 years ago in reply to TER

Yes, I just replace the overrides registers so that the settings are compatible with the CC2510. This setup works well while communicating using CC2650 Launchpad. I am trying to run the same rf settings for the CC2650 custom board to communicate with CC2510.

0 Rahul Gusai over 4 years ago in reply to TER

This is the exact RF design used in our custom board. The only difference between this design and that of CC2650 Launchpad is that this one is externally biased. But only Launchpad is able to communicate with CC2510. I am using the same RF settings while running on each of the boards.
