How to use the ST-LINK V2 for debugging using 'printf' ?

Hello,I have a ST -LINK V2 programmer. I use it with Nordic nRF51822 to program the nRF via SWD.I want to debug my code by using 'printf' commands using the same ST-LINK V2; is it possible?If yes, how ?What is the SWIM pin for ?Thanks.

Why does BlueNRG-MS, v7.2c, fail on this simple call: aci_gap_start_general_conn_establish_proc_IDB05A1(ACTIVE_SCAN, 192, 96, PUBLIC_ADDR, false); with error code 0x42 #define BLE_STATUS_INVALID_PARAMS (0x42)

BlueNRG-MS is initialized with CONFIG_DATA_MODE_OFFSET as Mode3 or Mode4, still fails.BlueNRG-MS is initialized as GAP_CENTRAL_ROLE_IDB05A1.BlueNRG-MS is not otherwise scanning or advertising or in a connection as a master or a slave.Note that genera...

Please advise me on a basic strategy for adding BlueNRG2 STEVAL-IDB008V2 button press (PUSH1 or PUSH2) recognition to the Android ST BlueMS application.

My application is to have an Android app that detects a single GPIO input (a button press) from the BlueNRG2 module. Is there a more simple starting point than the BlueMS application and it's companion firmware project? I am using Atollic (thank you ...
