Yes. The different softdevices use a different amount of memory. Is it possible for you to download Keil? Then you can use more of out support material like guides and tutorials.

Anders, I am using SDK 11 to flash the hex file provided by the SDK. When I tried flashing the image of SDK 11 on the nrf52 dk after flashing the S132 using nrfgo it prompted me an error that I am writing into the soft device region. Then I erased it and programmed again it worked. But when I tried the same thing for my custom device, it didn't work. Do I need to change something in the script to flash the firmware ?

I use the following script to flash the image onto the device usin jlink,

device nrf51
speed 1000
w4 4001e504 2
w4 4001e50c 1
sleep 100
r
loadfile s130_nrf51_1.0.0_softdevice.hex 0x00
loadfile app.hex
r
g
exit

I was using MCP for Android. Ok I will try with the nRF Sniffer and update you. I checked for the device using raspberry pi but I could not detect anything, Yes I using the project ble_app_hrs_rscs_relay.

Are you using MCP for windows or Android? You can also try to set up a DK or Dongle as a nRF Sniffer, to ensure that you are advertising. It seems strange that other example projects work on the custom device, but not this one. Just to be sure, you are using the project called ble_app_hrs_rscs_relay? You did not state this explicitly in your post.

Anders, yes it does have an external oscillator of 32.768 K and the IC revision is 3 (QFAAH0). I do not have a debugger program. Maybe I will check it out. The problem is the LED indicates that it is advertising but it is not. I will update the question and add the schematic of the chip .

Tell me about the custom device. Does it have an external oscillator? Which revision of the nrf51822 does it have? You can use the jlink to debug the program, if you have a debugger program. Keil is a popular program for programming and debugging the nRF51. See the getting started section on infocenter.

I have tried the example on the development kit and it works fine, but when I flash the same code on a custom device it does not advertise anything. But all the other applications work just fine. I flash the code using Jlink terminal (by connecting SWDIO and SWCLK. So I don't know how to provide any extra information. Does it have something to do with the pin configuration?

Can you run the central/peripheral with a debugger? Or print some info to a terminal about what is happening? You must provide something for us to work from :)
