Experimental: ATT_MTU Throughput Example results in fatal errors?

[ryerye120]

Hi,

I'm using two nrf52840 Dev Kits and am trying to test out the ATT_MTU throughput example with SDKv16. Whenever I program one of my boards I get repeated fatal error 7 (invalid param). I've used these for multiple other BLE programs so they certainly have soft devices installed...

Is there something simple I'm missing?

Thank you!

Hi, 

Did you modify the example code? If so, what did you modify?

Try to Erasing the kit before programming the image.

Hi Amanda!

I have not modified the code (yet)! Does SES not erase the memory before uploading a new build?

Thanks,

Ryan

Hi, 

I don't think all the contents of the flash gets erased when Segger load a new build image. Before you program an example to the development kit, you should erase the contents of the kit.

Worked like a charm, thank you!
