5.1 How to Use

The power measurement application enables to switch between the various use cases and to configure the device settings through several global variables declared at the top of the main file. The table below describes how to use them. For your convenience, some defines were already created for all possible values. Note that if the user works in interactive mode the use case and socket type are set interactively, while the other (advanced setting) still needs to be defined in source code.

Table 5. Power Management Configurations

Variable Name Value Remarks
g_ActiveUseCase HIBERNATE_MEASURE Hibernate Current measurement mode
SLEEP_MEASURE Sleep current measurement mode
TRANSCEIVER MODE
ALWAYS CONNECTED USE CASE
INTERMEDIATELY CONNECTED
g_SocketType UDP SOCKET
TCP SOCKET
SEC_TCP_SOCKET Note: For secure socket there are default values for cipher & method variables.
g_IpV4Option STATIC_IP The Address value is defined in the "MY_IP_ADDRESS" define statement.
DHCP Obtain IP address through DHCP process.
g_CcaBypass 0 This variable is relevant only on Transceiver mode, the default value is 1, aka bypass the CCA
