Current measurement

To monitor the power consumption of the BlueNRG-MS X-NUCLEO-IDB05A1 board, insert
an ammeter probe between pins 1 and 2 of the jumper on the J1 connector. Since the
power consumption of BlueNRG-MS is very low during most of its operating time, an
accurate instrument in the range of a few µA may be required.
