Where to get the matching configuration and how to measure the current on every status?

Question

Hi, 
 
 I use the nrf51422 chip.I want to know if the ANT establish link between chips,where can I get the matching configuration (like device type、channel ID).I mean is there a register or a function that can get those things. 
 I use the example ant_broadcast to measure the current on ON MODE、LOWER POWER MODE etc.And I use :
while(1)
{
err_code = sd_app_event_wait();
}
to measure the lower power mode and I get 0.1mA.
I delete the sentence err_code = sd_app_event_wait(); to measure the current when the chip is sending the dates and I get 4.8mA.I think the current is too big and there must be some mistakes but I don't know how.Can anybody tell me what's wrong or is there other way to measure the current.Oh,by the way ,I shut down the Led ,and remove the Jlink when I measure the date.
