Hi,
I think our only m0+/802.15.4 board is the samr21-xpro and there are problems
with the current/old network stack because of its memory demands.
That said: which protocol on top of IP are you interested in?
I assume you want to ignore RPL and any other side-tasks for this evaluation?
Cheers,
hi ,
this is the diagram used for BLE software architecture
what is host and controller in this figure ?
Is this the correct way to approach the Project N2 - BLE stack?
thank you

Hi,
I am a Computer Science Engineering undergraduate from University of
Moratuwa. I am very interested in IoT related projects and writing low
level high performance code with C/C++.
Most interesting idea I found was 'Support for Bluetooth Low Energy aka
Bluetooth Smart'. I think when it comes t
Hi Craig,
We have a 802.15.4 transceiver that is capable of 250kbps. We are
thinking of using this with a Cortex M0+ but wanted to make sure that
the M0+ would have the processing power to handle the
802.15.4/6lowpan/ipv6 stack at a datarate of 250kbps.
I just wondered if anyone had done any
Hi Simon,
Throughput will be highly dependent upon the RF environment and what
transceiver you are using. The M0+ most likely has enough power to do it
under ideal conditions, but retransmissions due to collisions will limit
the effective bandwidth.
You can use 900 mhz and 2.4 ghz transceivers wi
Has anyone done any performance tests to see what throughput can be
achieved using RIOT?
I would be interested to know if the Cortex M0+ is powerful enough to
sustain 250Kb/s TCP over 6lowpan/802.15.4.
Does RIOT have any mechanism to measure CPU usage?

That's fine :-)
Great! I'm looking forward to seeing it.

I would agree with Mart
Hi Baptiste,
I was/am extremely busy with non-RIOT work, so please bear with me ;)
An update will follow soonish.
If you're on a deadline say so and I can look if I can squeeze it in somehow.

Ludwig

Hi Joakim,
sorry for the silence on this. The driver is almost ready I’ll open a
PR for it by Thursday at latest. I was discussing with Hauke the initialisation
process for the network stack and also initialisation in general.
I saw these memory corruptions too, but didn’t manage to identify the

I can remember having the same problem with the telosb. I traced it down
to the fact, that there are no interrupts triggered. Which is strange
as the same code is working on an other msp430/cc2420 platform (Zolertia Z1).
Maybe a misconfiguration somehow sneaked into the radio driver setu

Hello Joakim,
currently there are no specific plans to utilize the power modes of the
radios to my knowledge, except that mostly MAC/link layers will implement
it. So if you have any idea: feel free to speak about it.

Hello RIOTers,
What is the current state of radio duty cycling in RIOT?
I know that radio drivers implement on and off functions for the chip, but
how do we make the best use of them?
In order to reduce power consumption it will be necessary to duty cycle
