Hi.
oki, in case i'll add some explanation.. I'll be busy for this week but you can simply use the serial gw example from MySensors for getting started, this should work. I didn't need to create a special board in arduino for this board, so if you're using it, you'll need to install&use the mattairtech SAMD21 board definition for the pin mapping.

Hi,
Can You share sketch example for SAMD21E and RFM69 node?
MiKa

I have just assembled another one for a friend. Works very well with mysensors 2

Same pcb for the two's of course, I like the rgb led with the indication led api ;):

• on left, long range RFM95 GW usb dongle.
• on right, RFM69 High power GW usb dongle.
• bottom, a multisensors I have just assembled.

As I see the development based on SAMD21 enfold, the behaviour brain I'm building for my mobile robot would be better based on that processor instead of the atmega1284p I'm using now.

ok. I saw this before, but didn't know where it was located. great, thx
so I will install a doxygen plugin I will try to add the docs. In code it's always useful, but like doxygen does is the next step I was searching for. I was pretty sure there was something like this: doxygen lol! I will sleep less dumb tonight

Yes we have, but it relies on contributors using doxygen (and only parts of the current code is documented properly).

I have looked at Tekka lib, thx
For convenience, for the moment ;), I have almost repackaged radiohead and rfm95 parts into something "standalone" (like lowpowerlab certainly did for rfm69). I keep from radiohead a few more getter/setters because I like it lol.

Basic things compiling&working, argh not in mysensors yet, as I'm still on the driver part. I'm trying to follow a bit the lowpowerlab flow, so it will be easier then for a rfm95transport. Still lot of things to check, wip..but for the moment, for a simple raw reliable (sendWithretry) sketch, I get something 17% flash, 25% ram for a 328p...compared to 49%/80% using radiohead lib. I hope things won't grow too much, I will try to get things compact as I can

Though, there were interesting things in radiohead lib:

• the way it's structured (a bit like mysensors, with a radio driver, spi and more general/generic layer).
• I have not tested it but you can handle multiple int and radio for instance.

It was a bit of work to navigate in, to be sure to not forgive something, not a nightmare lol hopefully radiohead has a great and well done documentation.
Talking about this..do you have a doc like this for mysensors, for the description and class hierarchy? just curious

See you soon

@scalz
You could look have a look at the new minimal rf24-driver made by @tekka. It contains the bare minimal needed for communicating.

If the radiohead/rfm95 driver can be transformed into something similar, then go ahead.

I'm playing with radiohead lib now. nothing special but that works well too

I have looked a bit at LMIC (radio management+protocol), for curiosity. I like the the "rtos" style, it's well done, sure, but it's mostly another protocol... there are nice things though.

I think, the best, imho, would be to extract radiohead rfm95 driver and make something like rfm69 lowpowerlab lib. Or trying to add radiohead to mysensors..In each case, that is some stuff&debug.

Now, I would like to have my lora nodes in mysensors...so what's next?...no, no, don't say what i haven't said ...

few other pics, a bit better quality

I've not used oven this time. just handsoldered. 0603. I've not tried yet, to use pcb only for plugging (without connector), I will do (it could be smaller) but I prefer/more confident with a connector.

funny and tiny, not so much feature, there are other boards with more pins but I wanted this one simple, with minimal mysensors things, when I will receive my jst, I will have more pins like i2c. but for the moment, I like it connected directly in usb without wire, playing with arduino, neopixel, serial and radio etc..like a child
