Hi
I'm trying to program a nRF51 DK (pca10028) with the heart rate demo "ble_app_hrs_s110_pca10028", but for some reason it doesn't respond... at all.
I started off by copying the "ble_app_hrs_s110_pca10028" example code from the pack installer in Keil and proceeded to build and download the solution apparently without errors or warnings (see result below).
Yet still nothing happens. The BSP_INDICATE_ADVERTISING state is not indicated, the device doesn't show up in the master control panel and nothing happens when i press any of the buttons.
What's even more confusing is that the old code present in the flash sometimes continue running even after the hrs app supposedly downloaded successfully. Case in point; I tried the blinky_led example code first and got it working right away. I then tried the hrs app as explained above, but the leds were still blinking along merrily despite Keil claiming to have erased, programmed and verified the the new code.
Does anyone know what's going on here?
Thanks in advance!
