There is flash algorithm/target in Keil for flashing softdevice in later SDK versions, but not in SDK v7.1.0. I do not know if there are any tools that can be used to flash hex-files using ST-Link devices, maybe OpenOCD?

nRF5x devices only supprt SWD interface, no JTAG.

I would recommend getting one of our developement kits. The kits have on-board J-Link debugger that can be used for flashing external devices. You should also be able to use any J-Link debugger.

flash_s132_nrf52_2.0.0_softdevice, is a Programming Algorithms found in KEIL?

I'm using device ST-Link/V2 in SWD mode.

Is my mode wrong? Do need JTAG mode?

Can the use the ST-Link/V2 Programmer solve problem?

Or do I have to buy a Segger Programmer?

If I have to buy a Segger Programmer, will EDU version solve the situation?

Or do I need to get a Segger Programmer PRO version?

BLE firmware requires Softdevice to function. It is the BLE stack. Without it, you cannot do BLE firmware.

I just want to program full empty chip on pca20006.

I using ST-Link/V2 tool, program and debug is success.

Demostration card on led blink not problem.

I using flash algorithm for external connection.
->C:\Keil\ARM\PACK\NordicSemiconductor\nRF_DeviceFamilyPack\8.16.0\Flash\nrf51xxx_ecb.flm

Available 31.768khz crystal on pca20006 board.

I try external and internal clock source but not changed.

Problem only Bt Adversing nrf51822 chip. ble_stack_init method inside sd_softdevice_enable

Can I do without using sd_softdevice_enable function?

I only need to one way broadcast a 30 byte beacon data in 1 second.

UUID and MAJOR and MINOR definations on hard code will be.

Hi,

Did you flash the softdevice? There is no target in the Keil beacon project to flash the softdevice. You need to flash it using external tool.

Best regards,
