nRF52833 to nRF52811

[Siddharth Venkatesh]

Hi 

I currently have a nRF52833 DK which I am using as a transmitter. I also have a custom board with a nRF52811 SoC with an antenna array to act as the receiver for AoA. 

I previously had an antenna array attached to a nRF52833 DK which acted as the receiver and it worked really well. Now when I try to upload the same code onto the custom board with the nRF52811 SoC its not reading any values. By values I mean I am not getting any I/Q samples. 

1. My main question is do I need to change anything in the "radio_config.c" file for changing between nRF52833 and nRF52811. I think I have successfully changed the project configurations because everything compiles and downloads well. I can also control the UART and the LEDS on my custom board with nRF52811 SoC. So I think the problem should be with how I have configured the radio. 

If you think I should change the radio_config.c file I can upload it after I see what you guys think. 

Cheers

Sid

Hi Sid,

Can you check that you are using the right start-up files for the nRF52811?

You can also check that the preprocessor flag NRF52811_XXAA i set in the Preprocessor definitions:

You could also send your HW files to us so we can review your custom board. You could for instance check you are using the right values for the crystal capacitors based on the load capacitance given by the datasheet of the crystal. The formula for calculating the crystal capacitor values is:

C= 2 * CL - 4pF

Best regards,
