PCA10028 not discover in mobile

[hiren]

Hii, i use nordic PCA10028 dev kit, to test the bluetooth of kit i simply load the ble_app_hrs example which is given in SDK, because of i don't know how softdevice 110 is use i change the RAM and ROM address to iROM1 0x0 0x39000, iRAM1 0x20000000 0x8000 and generate hex file and load it using nrfgo studio, and than i search bluetooth in my android phone which has "jelly bean" OS but i can't find the bluetooth of kit. and than to check tha RAM and ROM address are right or wrong i change the RAM and ROM address of LED blink example of S110 which is also given in SDK and it's work fine. Anybody can tell what mistack i have done ? and if you have the example of that than please give.

Hi, the linker settings are wrong for the s110 softdevice. The correct settings are set by default when you open a new SDK project. S110 softdevice specification chapter 10 provides an overview of the memory allocation when using S110 stack.

Also, to run the s110 examples in the SDK, you need to pre-program the softdevice binary. You can use nRFgo studio for this (win32 win64). The s110 softdevice binary is available here
