I was able to reach the shell using the radio, but I have some questions.
I have a CC1101, it seems to me that CC1100 is different, both are usable with the driver right?
I’ve tried to make gnrc_networking example to work, using the instructions of Kapsar which I’ve found on this mail list:
1. create a file "cc110x_params.h" and put it in your board's include/
directory. See "boards/msba2/include/cc110x_params.h" as example. You
have to put the right parameters for your board.
2. Add these lines to your board's Makefile.include:
ifneq (,$(filter gnrc_netif_default,$(USEMODULE)))
USEMODULE += cc110x gnrc_netdev2 gnrc_cc110x
3. Append these lines to Makefile.dep:
ifneq (,$(filter cc110x,$(USEMODULE)))
DISABLE_MODULE += gnrc_sixlowpan_iphc
4. make clean all flash term ...
The next steps depend on whether your board has an implementation of
cpuid. Check that by typing "ifconfig" and see whether
"fe80::201:203:405:607/64" is every node's link-local address.
If they're different and unique, continue at step 6. Otherwise, manually
set new addresses:
5. on each node, enter these lines:
ifconfig 7 del fe80::201:203:405:607
ifconfig 7 set addr <n>
ifconfig 7 add fe80::<n>
(replace <n> with any hex number from 1 to fe)
After the nodes should be able to ping each other at fe80::<n>.
6. on one node, type:
udp server start 12345
7. on another node, type:
udp send <other-node-ip> 12345 TEST
(replace <other-node-ip> ...)
By the way I’m using this module using a simple 164 mm antenna made from an UTP cable wire in a breadboard, the module is also in the breadboard with ~10 cm wires.
The modified Makefile.dep is the one in the root folder.
I’ve also enabled debugging in the CC1101 driver files and added a small segment to the setup, which prints out the configuration/status registers, so I can see that the connection between the board and the radio works properly, and it does indeed.
ifconfig tells me this:
-Iface 7 HWaddr: 20 Channel: 0
-MTU:1280 HL:64 6LO RTR IPHC
-Link type: wireless
-inet6 addr: ff02::1/128 scope: local [multicast]
-inet6 addr: fe80::3600:3400:757:3156/64 scope: local
-inet6 addr: ff02::1:ff57:3156/128 scope: local [multicast]
If I set the channel it says:
-ifconfig 7 set chan 8
-success: set channel on interface 7 to 8
But if I write in ifconfig again the “Channel” parameter stays on 0.
So I’ve continued with point number 5 with:
-ifconfig 7 del fe80::3600:3400:757:3156
-ifconfig 7 set addr 1
-ifconfig 7 add fe80::1
even though our adresses were different. I’ve tried this on different channels.
After this I’ve started the udp server with:
-udp server start 12345
After that I set up the other node similarly and write:
-udp server start fe80::1 12345 TEST
And every type I try that then this appears on the first nodes terminal:
This line also appears randomly sometimes.
I’ve also tried txtsnd 7 20 HELLO and txtsnd 7 fe80::2 HELLO with no success
This also appears in the console:
-cc110x: snd pkt to 0 payload_length=28
-cc110x_isr_handler() RADIO_TX_BUSY + GDO2
I’ve ran a debugger and it really sends something, but not a text apparently.
What am I missing?
