6 Dust Networks ETERNA1 Regulatory User Guide
2.2 API UART
ETERNA1 offers a comprehensive Application Programming Interface, API, that provides full programmatic access to
control the device, monitor its status (such as battery charge and network status), and provide access to the wireless mesh
network. Messages over the API UART are HDLC encoded and require specific software to support command and response
communication required for regulatory testing. Refer to the SmartMesh API Guide for details.
3 Test Configurations
Test configurations can be divided into two distinct configurations, one for Radiated immunity and a second for Emissions
and Conducted Measurements.
3.1 Radiated Immunity
Operation of the network in the presence of an interferer can most easily be monitored by operating ETERNA1 as a mote
participating in a network. In this configuration, the RF link between the ETERNA1 and a network manager can be
exercised and simultaneously monitored via the network managers UART CLI port. Communication and monitoring to the
UART CLI port can be done via generally available terminal emulation software, such as TeraTerm, HyperTerminal, or
iTerm2.
3.2 Emissions and Conducted Measurements
Emissions and Conducted measurements can be made with ETERNA1 integrated into a product or stand alone. When
integrated into a product a convenient method to invoke commands over ETERNA1’s CLI or API UART should be
considered as part of the product design. To access the CLI port and power on ETERNA1 in a stand alone configuration, a 2
mm header should be installed on J4, as shown below,
J1 and J4 per the pinout shown below, provides both power and connection to ETERNA1’s CLI port. Connection to pins
J1’s pins 3 through 11 are optional for CLI access.
