Got it, i was making mistake. i am using the accelerometer in the code and that was disconnected thats the reason it was calling main function again and again. Issue resolved. Thanks for Support Jorgen.

Yes examples are working with vs_uuid_count = 1 but main app still stuck its main function is getting called again and again and its not able to advertise in ble mode.

Have you tried with vs_uuid_count = 1? If you increase this parameter, you will also have to increase the RAM size for the softdevice. You can edit the RAM start and size in the linker script, found in the armgcc directory where the Makefile is located. For the proximity example with vs_uuid_count = 2, the settings should be:

MEMORY
{
  FLASH (rx) : ORIGIN = 0x1f000, LENGTH = 0x61000
  RAM (rwx) :  ORIGIN = 0x20002138, LENGTH = 0xdec8 
}

Hi Jorgen I simply compiled the proximity example and tried flashing hex file from _build folder without any changes in the code. it seems there is issue while generating hex file. initially I made two changes in the p_ble_enable_params->common_enable_params.vs_uuid_count = 2; // original 1 in the soft device_handler.c. this is our requirement for adding more services. and in makefile CFLAGS += -Wall -Werror -O0 -g3 made 0 instead of 3 to reduce compiler optimisation.

other than that no changes made anywhere apart from path and version names in gcc.

Which example? Have you made any changes to the code in the example? Have you tried debugging the application as described in the Eclipse tutorial? This post describe how to check error codes etc.

first erase all using nrfgo on program soft device tab program with components/softdevice/s132/hex/s132_nrf52_3.0.0_softdevice.hex tried flashing newly built hex file from "_build" folder which nrfgo reported done successfully but its not working as no led blinking and no ble device in the nrf connect app but if I am using existing hex files from example from hex folder then its working fine.

Could you provide some more details on what is not working? Which example are you building and flashing? If this is a BLE example, did you flash the correct softdevice first? How are you flashing the hex file?
