ConnectCore® 6UL Hardware Reference Manual
118
n One Ethernet interface up and linked. The other one disabled.
n USB connected to the system.
n Hanoi application running. (The Hanoi application stresses the CPU and put it at 100% work
load.)
Wireless
In all other use cases, wireless was disabled in order to ease the power consumption calculation. This
dedicated section describes the power consumption of the ConnectCore 6UL modulewhen
transmitting (in test mode) in different wireless modes on both 2.4 GHz and 5 GHz channels (see
Power consumption: Real wireless transmission):
2.4 GHz:
n 99% time transmitting.
n Channel 6 (2437 MHz).
5 GHz:
n 99% time transmitting.
n Channel 120 (5600 MHz).
In the real wireless transmission scenario, the ConnectCore 6UL module is connected to an AP
(transmitting and receiving):
n Ethernet disabled.
n 50MB file transmitted and received between the DUT and the AP.
n Connection in the 802.11g/n mode at 2.4 GHz (2437 MHz channel).
n In a real wireless transmission, modulation and bandwidth are configured automatically.
Wireless UART Bridge
Hardware setup
n ConnectCore 6UL module mounted on a SBCExpress.
n UART4 connected to a host PC serial port (through a TTL-to-RS232 adapter).
n Console connected to the host PC.
Test case configuration
n Continuous traffic through the UART4, commanded through the Console port (stressing both
UARTs):
l Checks all bit rates below 115200.
l Checks different parities and packet sizes.
n Wireless up and running:
l 100 K file transmitted and received between the DUT and the AP, so there will be also
reception through the wireless interface. The test is continuously sending the packages, so
more than one transmission is executed every five seconds.
l Connection in the 802.11g/n mode at 2.4 GHz (2437 MHz channel).
n I2C1 bus up and running (no specific actions taken on this interface).
