[riot-devel] Help with SODAQ SARA SFF needed

[Oleg Hahm]

Hey folks,

I'm currently trying to get RIOT to fly on the SODAQ SARA SFF board.
Unfortunately I'm struggling a little bit with the startup sequence of the
U-Blox module. According to the documentation here:
http://doc.riot-os.org/sodaq-sara-sff_2include_2board_8h.html and the Arduino
samples provided by SODAQ I assumed that I would need to call SARA_ENABLE_ON
and SARA_TX_ENABLE_ON, followed by toggling SARA_R4XX_PWR_ON_PIN, but I still
fail to read the firmware via an AT command. Anyone with experience with the
SODAQ boards and the SARA U-Blox module?

Cheers
Oleg

Hi Oleg,

I started a driver for the Ublox device on this branch [1]. It is
limited but it is working on the SODAQ SARA AFF board. I don't know if
the pins change on the SFF version of the board, but you can give it a
try. Hope that helps.

Cheers,
Leandro.

[Emmanuel Baccelli]

Dear RIOTers,

The fifth RIOT Summit  will take place on
September 14-15, 2020.

The event is online. Two days feature single-track presentations,
breakout sessions, and a hands-on coding tutorial. If you
want to attend, please register as soon as possible via
https://riot-summit2020.eventbrite.com/ .

**Talks**

Keynote : "Smaller is Safer" by Andrew S. Tanenbaum.

Further talks will cover IoT Security, IoT Networking,
Energy Management, and IoT Use Cases & Applications.

More speakers: https://summit.riot-os.org/2020/#speakers

**Tutorial**

A half-day webinar will guide newcomers on Day 1
including a series of hands-on activities with RIOT.
No specific hardware necessary, attendees will
be given access to the necessary online tools,
and instructions on required preliminary setup.

**Agenda**

Full program at a glance:
https://summit.riot-os.org/2020/#program

[riot-devel] Help with Modular Network Stack

[nagrawal]

Hello everyone,

We at IBR, TU Braunschweig are trying to implement a truly modular 
network stack where different components of the network stack like 
Network layer, transport layer, framer, duty cycling can be interchanged 
with different implementations without touching the code of other 
layers.


The current GNRC implementation is mostly designed around the 
traditional TCP(/UDP)/IPv6 network stack since the neighbor information 
base stores ipv6 addresses, implements NDP and RPL (both designed for 
ipv6).


The goal is to bring the modularity of Contiki-NG's network stack to 
RIOT. The motivation behind this is that we would be able to have many 
more different implementations like Rime and switch between these 
different implementations easily (just a small change in the Makefile). 
Also, from a developer's perspective it would be really easy to 
understand and implement new things in the network stack since he/she 
wouldn't have to understand the implementation details of the other 
components of the network stack.


This logically is supposed to be attained by implementing structs 
representing each part of the network stack (Eg: A common struct for 
routing protocols which has function pointers each routing algorithm 
will have to implement like in [1]).


Could you guys therefore guide towards implementing such a modular 
network stack ?



Regards,
Nishchay Agrawal

[Oleg]

Hey Leandro,

that looks very helpful indeed - thanks a lot!

Unfortunately, I still get no response from the modem - but the Arduino 
example isn't working either, so maybe it's a problem with the hardware.


Cheers
Oleg
