Hello,

Thank you for your answer.

I am using: Simplelink_cc26x2_sdk_2_30_00_34.

Hello Sidi,

Based on the SDK you are using I suspect that you use HW Rev C of the CC2652R Launchpad?

This was a pre-released CC2652R Launchpad that are not supported anymore. You need to get a hold of the new Rev E Launchpad.

Hello R.M,

I use HW Rev B of the CC2652R Launchpad.

 
Do I have to change the CC2652R Launchpad?

Best Regards,

Sidi

Hello Sidi,

If you are using HW Rev B of the CC2652R Launchpad you should not use SDK 2.30.00.34. The 2.30.00.34 SDK are for a pre-released Launchpad (Chip revision C) and will not work on the new Launchpad (Chip revision E). Please upgrade to a newer SDK release and try again.

I change the SDK and i use use now  cc13x2_26x2_sdk_3_30_00_03 .

Now , the buffer is not = 15 (SSI_STATUS_MASK)  but the data receive pointer value  is always = 0;

This is how i get my data : SSIDataGet(SSI0_BASE, &uRcvData) ;

Hi Sidi,

Do you know if you actually have received any data? Do SSIStatus() function return with status 4 or 8? 

If not, can you probe the SSI lines and see what that is transmitted and received?

Hello R.M,

I probe the SSI lines and i see that my Master ( CC2652R Launchpad) sends a data (MOSI RUN  but My MISO doesn't change).

I think that the slave doesn't receive a data.

Hi Sidi,

So if you do see data being send from the CC2652R and no response from TRF7970a the problem is most likely not the CC2652R.

What commands do you send to TRF7970a?
