Re: About the transceiver and sending packets to / from a hardware

[Bastian Bloessl]

Hi,

you're right, the RIME stack is a network stack. But it is completely
optional. You can just disable the block if you don't need it. It was
just convenient to setup connections with Contiki running on a TelosB node.

If you use something different than Contiki (i.e., a node w/o RIME)
frames will not pop out of the RIME ports. But you will see all frames
that are received by the SDR in the Wireshark trace. It logs everything
that is received, independent from PAN ID, etc.

If you use other nodes, as Marcus said:
- check that they use the same PHY (O-QPSK in 2.4GHz)
- check that they use the same channel
- To RX with a custom node: implement a firmware that shows all frames
(independent from MAC, PAN ID, etc.)
- To RX frames w/ GNU Radio, you don't have to do anything special as
every received frame will show up in GR.

Some nodes with PCB antennas are not that great. If you have problems
receiving them with GR, try to (1) increase TX gain, (2) get it closer
to the SDR, (3) increase RX gain of the SDR.

Hope it helps,
Basti

Hello ,

   Regarding the wireshark packet flow stop i think Dr Basti gave a
solution on his website . I think i got it Mr.Marcus Muller , the solution
for the last question but still working on its implementation verification

Thanks and regards ,

Hello Marcus Muller ,

   Thank you so much for the reply . The thing about Rime Stack is rime
stack is a network level stack . So my question is if its network level
stack is that the block thats restricting me from getting other hardware
signals on the Wireshark ?? and I want to let you know that i am trying
different type of flow graph changes to make it work and i am posting this
after playing with MAC and Rime . I even tried to seperate the tx and rx
section to see if it is working but still it is not .


Thanks and regards ,

This is wireless communications. Not only do you have to configure all
devices in a compatible manner, channel and receiver conditions can make
interoperation problematic.

You will have to apply your own signal processing / wireless education
to debug this.

Same answer as to 1. You're not doing any signal-level debugging on
this, so we can't help you.

Re: About the transceiver and sending packets to / from a hardware

[sampath ranga]

Hello Everyone,

1. I was trying for the past few weeks to make the Zigbee Trx
communicate with the other Zigbee hardware for implementation verification
. I am not using TelOS b mote with COntiki Firmware instead i am using a
Zigbee dongle as a hardware to make the communication work . My question is
why is the flowgraph restricting only to hear the "hello world" message but
not the message from other hardware? If my SDR could operate at 2.4GHz in
air , the transceiver block should not only hear the "GNU Radio Transmitted
message but also from the other hardware isnt it? The other hardware is
also not receiving the GNU Radio's message.
  2. Is the Rime stack / MAC layer that fixes frames stopping the other
hardware to send or receive?
  3. I am also trying the same Zigbee Trx in 2 laptops, the message that i
set in laptop 1 at GNU Radio Zigbee TRX has been received in wireshark at
laptop 1 and laptop 2 message at laptop 2 , Why are not they syncing with
each other if i give same destination or pan id with channel number?

Technically i am trying to do 2 work , Either have two laptop that has each
flowgraph with 2 different message and wanna see if they both are
transferring their message at wireshark, which is right now not happening
secondly , trying to transmit Zigbee Trx basti's message to a seperate
zigbee hardware (Xbee or any zigbee sniffer) or send message from Xbee and
trying to receiving in on Wireshark at the GNU Radio end

I also face the issue of when i transceive the message its showing "Bad
FCS"  and also the packet flow is getting stopped when i open the wireshark
. Please throw some ideas on this .

Thanks and regards,
Ranganathan Sampathkumar

Hello Mr.Marcus Muller ,

   I totally understand and i apologize for not asking my question in

I'd respectfully like to point out that as an author and maintainer of
open source software, it's often a very time-consuming task to read the
private messages asking for advice about one's projects. Knowing the
less-than-amusing messages that show up on the issues on Basti's
software projects, I think it what reaches him in private actually be a
really bad burden for him.

It's really much better that you wrote here to the mailing list; in
general, unless it's really something that *must* be done in privacy,
it's polite to use the public platforms of open source projects and
communities. Thanks for reaching out in this public way!

Haven't played with in a while, but gr-ieee802-15-4 is at least as far
as I know a standards-compliant implementation: If you configure it in
a standards-compliant way, it simply "speaks" zigbee. 

> Can we use other Zigbee hardware to sniff the message?

Yes?

with what did you try? Notice that the Wireshark dissector might not
like the packet format of all capture devices.

There's different 802.15.4 PHYs, make sure you're using the same, and
appropriately configured, for your other device. There's more that can
go wrong here than can go right – employ your signal processing
knowledge and the Qt GUI sinks to inspect what you're receiving while
you are receiving it.

Best regards,
Marcus
