nRF51 dongle programmation

[Inia]

Hello, I have bought an nRF51 dongle with a SEGGER J-Link. I have downloaded all the SDK and everything from nordic website. If i open an ble peripheral example in uvision5, compile it and download it to the nRF51 dongle, it says it was a success to download it but it looks like the software is not working (not advertising led). I have tried to download the nrf51422_xxac_s130 and the flash_s130_nrf51_2.0.0-7.alpha_softdevice. Same results. I have tried with other ble peripheral example but not more success. What does i forget ? What am i doing wrong ? Is there a tutorial on howto programm an nrf51 dongle ? Best regards. Julien

Are you using right HW reference (header file) for your board? In nRF5 SDK examples it's typically sneaked as global define through Makefile (e.g. -DBOARD_PCA10031) or Keil project setting. Which exact SDK version and project you opened and compiled? Also note that for all BLE projects you must download proper stack aka Soft Device binary first (typically just once unless you change the version because Keil as well as other flashing tools can use just block erase for application memory area and don't need to erase whole chip - in that case you would need to flash SD again or use merged SD + APP binaries).

Thanks endnode. I don't know why my sdk version is so old, i had just downloaded it a few days ago. I am downloading the last version and wil try again your three steps and get back to you. Thanks
