<p><a class="user-mention" data-hovercard-type="user" data-hovercard-url="/hovercards?user_id=2041729" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/maribu">@maribu</a> Many thanks for your reply. With the help of your other previous replies, I tried gnrc_netowrking example(BOARD=nucleo-f103rb, actually stm32f103rct6 discovery ) successful by using cc110x (433MHz).<br>
By reference to <a href="http://onewrt.com/cc1101-6lowpan-in-riot-os/" rel="nofollow"></a>)<br>
Then, I found configure another address is very important.<br>
<code>ifconfig 7 add fe80::ff:dc</code><br>
After that, <em>ping6</em> and <em>udp send</em> can be used. And the signal is unstable, most likely because of the antenna.</p>
