# dtls_echo
|
|
|
|
This example shows you how to use TinyDTLS with the non-socket approach.
|
|
|
|
This code is based on ../gnrc_networking and ../gnrc_tftp.
|
|
Is a good idea to read their README.md's for any doubt of how making the
|
|
testings.
|
|
|
|
## SOCKET vs. Non-socket (GNRC)
|
|
|
|
This example is configured to use the GNRC instead of sockets (over GNRC).
|
|
At the moment, the configuration must be done manually in the Makefile of
|
|
this project.
|
|
|
|
## Fast configuration (Between RIOT instances):
|
|
|
|
Preparing the logical interfaces:
|
|
|
|
./../../dist/tools/tapsetup/tapsetup --create 2
|
|
|
|
For the server instance:
|
|
|
|
make all; PORT=tap1 make term
|
|
dtlss start
|
|
ifconfig
|
|
|
|
Do not forget to copy the IPv6 addresses!
|
|
|
|
For the client:
|
|
|
|
PORT=tap0 make term
|
|
dtlsc <IPv6's server address> "DATA TO DATA TO DATA!"
|
|
|
|
# Testings
|
|
## Boards
|
|
|
|
Those boards that do not support the `../gnrc_networking` example are included
|
|
in the `BOARD_INSUFFICIENT_MEMORY`, plus the board `cc2650stk`.
|
|
|
|
There are certain boards that are having issues with `crypto.c` and
|
|
`dtls_time.h` Which for now are in the the `BOARD_BLACKLIST`.
|
|
|
|
The boards that requires `periph_conf.h` are not tested.
|
|
|
|
Boards with problem type 1 (`crypto.c`):
|
|
z1
|
|
wsn430-v1_4
|
|
wsn430-v1_3b
|
|
waspmote-pro
|
|
msb-430h
|
|
msb-430
|
|
chronos
|
|
arduino-mega2560
|
|
|
|
Boards with problem type 2 (`dtls_time.h`):
|
|
cc2538dk
|
|
msbiot
|
|
telosb
|
|
|
|
Boards with problem type 3 (Redifinition):
|
|
saml21-xpro
|
|
samr21-xpro
|
|
arduino-uno
|
|
arduino-duemilanove
|
|
|
|
NOTE: Those on type 1 can be benefit of the following PR:
|
|
https://github.com/RIOT-OS/RIOT/issues/2360
|
|
However, there are still issues to fix.
|
|
|
|
NOTE: Those on type 2 can be fixed with the patch at
|
|
https://github.com/RIOT-OS/RIOT/pull/5974
|
|
|
|
## FIT-LAB
|
|
|
|
The code has been tested in the FIT-LAB with M3 motes.
|
|
However, erros can occurrs. Enabling the line `CFLAGS += -DNDEBUG` in
|
|
the `Makefile` reduces the risk.
