Example code "Template Application" doesn't work.

[Snakehater]

Hi all!

I flashed and got both SoftDevice s130 and the example code onto my nRF51802 without prior modifications.

I flashed softdevice according to: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_gsg_keil%2FUG%2Fgsg%2Fprogram_sd.html with the command 

nrfjprog --family nRF51 --program _build\xxx.hex

after erasing the board with "nrfjprog --eraseall"

And then I flashed the example code with 

nrfjprog --program _build\xxx.hex
nrfjprog --reset

after running make script.

I've read somewhere to use nRFgo studio to flash my softdevice and all but that application is just crashing all the time so I used above solution. The problem is that I can't get it to advertise, cause when I open nrf connect on my android phone, I see no device with name "Nordic_Template". 

I use windows 10, flashing a nRF51802 chip on a custom board, ie no dk.

Hi, 

Are you using a development kit for the nrf51 or is it a custom board? I see that you are using a custom board, have you followed the reference design and the design guidelines when design ? Could you share schematic and layout(GERBER) maybe?

Using nrfjprog is ok. 

have you tested any other application?

What SKD are you using ?

I have tested blinky but changed the board configuration and got the LED blinking. So it works. The custom board is not mine, it is salvaged from an old display controller, so therefore, I have no schematic. Here you have pic of the board, maybe not the best one but it's something: https://easyupload.io/vq7anl

You can add pictures or upload files here in Devzone:


It is preferable to do it this way as it will keep all the information here in the same thread on Devzone making it easier to follow in anyone else comes across a similar problem.

Great thanks!

The module seems ok, so the radio looks like it should work. 

nrf51802, here is a link to the SDKs and SoftDevices that are supported. 

SD 130 and SDK 12.3 is recommended. 

Is this what you are using ?

One thing I cant see in the picture is if there is a LF clock, looks like there is not one, so a typical issue is often that the clock source is not correct. 

You should also be able to use nrf connect for desktop  and the programmer app to program the device
