Connecting EVK-ODIN-W2 for wireless communication
When connecting an EVK-ODIN-W2 evaluation kit for wireless communication, you need to redirect
the TX channel from the C211 anchor to EKV-ODIN-W2 by modifying the jumpers on the J5 connector,
as shown in
. This connects the UART TX pin on the C211 to UART1 RX on the
EVK-ODIN-W2. See also the EVK-ODIN-W2 user guide

Power supply
When mounting an ODIN-W2 EVK, the application board is powered through the ODIN-W2 EVK USB
contact. No other power supply to the C211 board is needed.
4.3.2.4
EVK-ODIN-W2 wireless gateway configuration
For C211 wireless communication though an EVK-ODIN-W2, the EVK must first be configured as a
wireless UDP gateway. In this configuration the EVK can:
•
Connect to a Wi-Fi network
•
Automatically connect
to the UDP server at “
server_ip
” and “
udp_port
”
•
Startup in data mode
•
Set the UART to 1 Mbps with no flow control
