sample BLE beacon app for measuring energy consumption

[bios-bob]

i'm looking for an extremely simple BLE beacon app, which advertises (say) at 1HZ and then enters a "low-power" sleep mode....

there are numerous samples included in the SDK -- where should i start????

i've tried the (eddystone) beacon sample....  works fine -- though it's not obvious how to change the advertising interval....

more important, however, the target is consuming ~300 uA between advertising events....

is there a sample app that enters some ON_IDLE state with current consumption in the 1-2 uA range???

It was set to 5 dBm by this line in the proj.conf file: CONFIG_BT_CTLR_TX_PWR_PLUS_5=y.

I had also configured VDD to 3.3 volts  on the DK via the board configurator:

The other switches can also be switched off to reduce current leakage in sleep.
