Hello all,
I am working on some LoRaWan projects and I would like to know if someone
already started to port the Sam R34 xplained board to work with riot and the
lorawan aplpication example.
Previously I sucessfully built and run the lorawan application using STM32
B-L072Z-LRWAN1 board on both TTN and SPOT lorawan networks.
I also managed to get it working on my custom design board using the murata
CMWX1ZZABZ-091 and it works like a charm. my only real difficulty is the power
consumption as I did not manage to get the power management library working
like it should, but I will open a specific thread about this topic ;)
As microchip launched a new chip I'm interrested to evaluate this new lorawan
solution to get some serious alternative to the murata/stm32 one.
Until here, I defined a new samr34 cpu and sucessfully run some basic
application using riot os on the Sam R34 xplained board. Shell application,
push button and leds are working like expected.
I defined the internal SX1276 conenction (spi bus and internal IOs) and I get
some results :

Unfortunately I'm stuck here and I would need some help to get it working :)
I'm new to RIOT my code as not yet been checked with RIOTs coding convention
but I would be pleased to share my RIOT fork if some guys are interrested to
use the Sam R34 xplained board as a LoRaWan alternative.
Regards,
Noel
