Throughput test coded PHY

[mercimek]

Hi pals! 

I'm trying to establish throughput test with two nRF52840 DK and it works perfectly well except the coded PHY option. When I configure the phy option to coded, it gives this error I attached. 

 

How should I change the thruoghput example code? PS: I'm using SDK 15.3.0

Hi,

I didn't manage to reproduce it here. I used the sample from SDK 15.3.0 and two nRF52840 dev kits. Could you try to build the project with 'DEBUG' in the list of preprocessor symbols(or select Debug target if you use SES)? It will give a more detailed crash log, not just "Fatal error".

Here is another project that should let you measure throughput with coded PHY as well: https://devzone.nordicsemi.com/f/nordic-q-a/47073/general-questions-about-notifications-low-level-ble-packets-and-softdevice-phy-connection-interval-connection-event-length-att-mtu-and-dle/186303#186303  

Best regards,

Hello, I'm setting Coded phy from putty so I didn't figure out how to debug the system from SES. Can you please explain it a little bit more?

[mercimek]

I think it was already defined. Am I right?

And this is one time I got no error but test didn't established

Your screenshot shows the available build configurations, but it does not show what build flags each of them has. Did you find the list of Preprocessor Definitions as shown in my previous reply?

Thank you for your answer, I think I set it as you told and now I have a more specific problem. What do you think about it?

Yes, this looks correct. However, it was not the error I expected to see. Softdevice asserts are quite rare and are usually caused by erroneous code in the app. Please try with the pre-compiled hex attached below and see if you get the same result. I have not been able to replicate this assert here.
