Thakn you for your answer.
I added the suggested modul, but it din’t help.
My makefile includes now the following modules:
USEMODULE += xtimer USEMODULE += cc110x
Include packages that pull up and auto-init the link layer.
NOTE: 6LoWPAN will be included if IEEE802.15.4 devices are present
USEMODULE += gnrc_netif_default USEMODULE += auto_init USEMODULE += auto_init_gnrc_netif USEMODULE += gnrc_cc110x
Specify the mandatory networking modules for IPv6 and UDP
USEMODULE += gnrc_ipv6_router_default USEMODULE += gnrc_sixlowpan_default USEMODULE += gnrc_udp
Add a routing protocol
USEMODULE += gnrc_rpl
This application dumps received packets to STDIO using the pktdump module
USEMODULE += gnrc_pktdump
Additional networking modules that can be dropped if not needed
USEMODULE += gnrc_icmpv6_echo
Add also the shell, some shell commands
USEMODULE += shell USEMODULE += shell_commands USEMODULE += ps USEMODULE += gnrc_netdev2
How the development procedure looks like? What should i initialize my self and what is initialized automaticly? When I try to send a packege through UDP the data is not reaching the low level drivers of CC110x.
