ROHM-Open-Developers / Mbed 2 deprecated GR-PEACH_WlanBP3595AP_sample

This is a sample application program for GR-PEACH_WlanBP3595AP library. GR-PEACH_WlanBP3595AP library only works with GR-PEACH. This sample works as TCP socket sever, and this program sends a message when a connection is accepted.
