nRFgo Studio just started working all the sudden. there may be a glitch/bug so if it doesnt work for you just keep trying, close studio open retry, unplug device replug in, reset device, etc.

Plug in development board, double click on Segger 683928426. Press Erase all and wait for it to complete. In the program soft device tab, load the softdevice hex and press program and once complete, verify.

Repeat the process on the program application tab with the client hex file

With the battery in the sensor, Do the same for the sensor via the J-link ultra+ cable, programming the softdevice and server hex files (you will need to double click on the nRF5x Programming

(note that I got an error when programming the server hex but repeated the programming server hex step a couple times and although the error persisted, it was programmed successfully)

Unplug the jlink but keep the battery in.

2 for 2 of answering my own questions, not sure if this "tech support" is the greatest as it is almost a week later and a basic question could not be answered. hopefully my 3rd question will get an answer.

sounds good...

I downloaded the install file, executed it, restarted my computer and went to

C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin\nrfjprog

i open nrfjprog and a black box opens, some text quickly scrolls, and it closes. I dont know how to open the command line to enter the text above. also dont i have to put the hex files into a specific folder for the command line to be able to access them

Hi,

Replace the "nrfjprog" with "nrfjporg.exe".

If you install the nrjporg correctly, you should be able to execute the following command:

nrfjprog.exe --family NRF52 --program s140_nrf52_6.1.1_softdevice.hex --chiperase --verify

nrfjprog.exe --family NRF52 --program ble_app_blinky_pca10056_s140.hex --sectorerase --verify

nrfjprog.exe --family NRF52 --reset

Hi,

I suggest using nrfjprog tool to program and verify. Please refer to the Installing the nRF5x Command Line Tools page.

You can use the following commands to program the image into nRF52840 DK first, then your custom board.

nrfjprog --family NRF52 --program s140_nrf52_6.1.1_softdevice.hex --chiperase --verify

nrfjprog --family NRF52 --program ble_app_blinky_pca10056_s140.hex --sectorerase --verify

nrfjprog --family NRF52 --reset

Do the test with nRF Connect as described in BLE Blinky Application.

In your case, the (client) DK board 1 does not connect to the custom board. At first, you should check the behavior of the BLE Blinky Application on the custom board is correct or not. If the custom board cannot work as expected, I suggest raising a new case for that situation.

nope, can not program softdevice, dont know how, my attempt with j-flash is just a guess

Hi,

It seems you can program the SoftDevice successfully now. The latest question runs away the subject, and you have already raised new case for that. Therefore, I would like to close this one.

I even tried to open the softdevice hex and merge blinky hex with it but no luck.

Using J-Flash, Project settings, In the General tab I selected USB Device 0, Target Interface SWD and 4000kHz, MCU Device: nRF52840,

Then I did File Open Data File, opened the hex file, then target connect, target manual programming erase, target production programming, it was programmed and verified successful. So I downloaded blinky to it again but same problem where LED 2 on the central never turns on.

any ideas, i have been searching the web with no luck. I have 2 development boards and load the client central BLE blinky to 1, then the peripheral BLE blinky to 2. when they power up the LED 1 on board 1 switches off and LED 2 switches on. This happens with no button pushes, only powering up. I remove development board 2 and replace it with my custom board and program my custom board with the exact same peripheral BLE blinky and power up and the central development board stays LED 1 on and never switches to LED 2. This is why I am thinking I need the softdevice loaded on my custom board. there is only 1 blue tooth antenna.

I am not. I have a nrf52840 development board which i have been programming with a USB cable and a custom board which has an nrf52840 which I have been programming with a J-Link

Hi,

It seems you are trying to program softdevice on nRF52840 Dongle. If so, you could follow the nRF52840 Dongle Programming Tutorial to program with nRF Connect for Desktop. It will be easier.

Best regards,

Amanda
