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.
