Help running BLE APP ATT MTU THROUGHPUT example

Hi,

I am trying to replicate the "Throughput and long range demo" from devzone.nordicsemi.com/.../

I have two nRF52840 boards. I am using IAR studio. I can compile, build and run the blinky demo without any problems. However whenever I try to do anything with Bluetooth I am running into a brick wall.

First question. How do the Softdevices work. Are they something that is flashed onto the device or is it a library that is linked against during build. I have SDK 13 and I also have downloaded s140 5.0.0.3-alpha.

If I have the blinky program running and then download and run a build of a Bluetooth program then the LEDs keeping running, almost as if the board didn't get reprogrammed, but IAR says there is a debug sessions running.

Is that normal? Any clues about what I could be doing wrong?

Also, is there a way to get logging information from NRF_LOG_INFO without wiring up a serial cable? Over USB? Is that what the nRF USB port is for?

Thanks. Gary.

  • Update (3) So I can now get the ble_app_hrs demo to work when building from source using S140 v5.0.0.2.alpha. However it won't build with .3.alpha, there are compile errors.

    As for the throughput tests, I still can't get those to work with .2.alpha or .3.alpha. I can get it to build under both (there are two versions of the source code, one for each version of S140) but it doesn't do anything once flash over to the board.
