5.3 Power Consumption

The current drain from the Vcc power input line is dependent on various factors. The three most significant factors are the voltage level at Vcc, UART baud rate and the operating mode.

The hardware specification for the blu2i module allows for a voltage range of 3.6 to 6.0v at Vcc. Tests have shown that there is no significant difference in current draw when Vcc is 5 or 6V. Therefore the data presented below, pertains to Vcc levels of 3.6 and 5v only. Tests have shown that where power drain is an issue, it is best to keep Vcc at the lower end of the range.

The UART baud rate has a bearing on power drain because as is normal for digital electronics, the power requirements increase linearly with increasing clocking frequencies. Hence higher baud rates result in a higher current drain.

Finally with regards to operating mode the significant modes are; idle, waiting for a connection, inquiring, initiating a connection and connected. With connected mode, it is also relevant to differentiate between no data
