5.2 TCP/IP Sample Programs
We have provided a number of sample programs demonstrating various uses of TCP/IP for
networking embedded systems. These programs require that you connect your PC and the
BL2100 together on the same network. This network can be a local private network (pre-
ferred for initial experimentation and debugging), or a connection via the Internet.
5.2.1 How to Set IP Addresses in the Sample Programs
With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run
many of our sample programs. You will see a

There are some other “standard” configurations for
ent features such as DHCP. Their values are documented at the top of the

IP Addresses Before Dynamic C 7.30
Most of the sample programs use macros to define the IP address assigned to the board and
the IP address of the gateway, if there is a gateway. Instead of the

In order to do a direct connection, the following IP addresses can be used for the BL2100:
