This is about sdk

[mahone]

Recently I open the sdk of the nrf51422,there are some functions that indicate that they are come from the document call 'ant_interface.h'.But when I try to go to the definition of it,I find there are not such a '.c' document.That bothers me.Can anybody tell me where is it? Thx.

Mahone,

Have you make sure you have the S120 softdevice programmed ? If you add a break point after the call, which err_code you receive or it just can't never go through the line ? Also please check your target option to make sure IROM1 starts at 0xC000

Which hardware are you testing ? Is it our dev/ev kit or your custom board ? Please verify that you have the 32kHz crystal connected.

Hung Bui,

I use the nrf51422 device just for 1 month,so I don't really know how to have S120 softdevice programmed.Can you tell me what is it?Maybe I happened to do so. In the nRF51422_DK_UG_v2.0,it said I should change IROM1 starts at 0x20000,and the Size is 0x20000.IRAM10x20002000 the Size is 0x2000.Or can I say that the picture just set a example and it should starts at what you said? I test a custom board,the chip shows it's NRF51422QFAA.I check the introduction of the custom board,there are seems to have a 16kHz crystal .
