Thank you very much Stian! I wound up using cell phone with the nRF Connect app and running CTS.

You can start and stop advertising using the SD API documented here: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v6.0.0/group___b_l_e___g_a_p___f_u_n_c_t_i_o_n_s.html?cp=2_3_1_1_0_2_1_2_3#ga74c21287bd6cbcd5822bc73792f678d8

For connection you need a central to initiate the connection, so you can't just connect using some code in the timer callback. You need a central device as well. You can use the pc-ble-driver along with an nRF5 DK as a central on your computer. The pc-ble-driver comes with a python wrapper, so you can easily script something that will connect to the peripheral device at specific intervals.

Hi Stian. By "mode of the BLE service" I mean whether it's in advertising mode or connected to a device. I hope to run a sustained test for two weeks and cycle between these modes for portions of the test. I have been able to generate state changes based on a timer created from the timer library. Is there sample code for entering the advertising and connected modes using the program?

Hi, not sure what you mean with "mode of the BLE service" and "control the Bluetooth state". What kind of states/modes are you talking about?

In general, you can use the RTC to give you interrupts in specific time intervals. The easiest way to implement this is probably through the timer library in the SDK. Then you can change the mode/state in the callback function for the RTC timer.
