@ .Peter. - Oh, so I could call on the c++ project where the mDot lib is.
I just talked with Mike over at MultiTech and he thought that I might loose the LoRa certification if I used mDot with another language other than what it was certified in.
I am in Austin, TX, USA
@ terrence - Texas, USA … I’m in Europe and you know what the LoRa mDot modules are very hard to get in Europe even with the 868 MHz frequencies after all these frequencies are for the EMEA area, strange that one can get the Dev board without the module but not the module ?
… must be a reason that I seem not to catch … well, whatever …
For certification etc., maybe the Multitech guys can team up with the llilum team from MS and work out a plan to have llilum implement the LoRa C++ stuff without loosing the certification … could end up with a nice POC project for llilum.
@ .Peter. - Here are two of my sales contacts. They are great guys and might be able to help you out on your supply problem.
Brandon Dalida <BDalida@ multitech.com>
Mike Kydd <mkydd@ multitech.com>
That would be great if we could get the llilum/mDot project going. I will ping someone over there on the tech side and suggest it.
I have already ported a couple of MultiTech Dragonfly boards to NETMF - one with a 405 and the other with a 411.
Both have 4mb onboard Flash so have IFU over Cell…
Quickly looking at the mDot specs they are similar to the DragonFly so probably you could have a NETMF port with IFU.
Gotcha’s…

You will need to use a ST Link to flash TinyBooter then USB as per normal on Pins 8 & 9 for TinyClr and debug.
Not sure what pins are used for the LoRa side of things…[/ul]
Now if only there was another way… :whistle:
@ terrence - I’ve gotten to a bit more (and stand corrected) detail on the pins to use for the USB DM/DP pins used for a possible Tinybooter/netmf burn/debug.
As usual pins PA11/PA12 are used for this, since I couldn’t find pin PA12 on the mDot pin outs as displayed in f.e. mDot dev guide on page 10 I assumed it was not avail, BUT I need to correct that, PA12 is on pin 8 whereas PA11 is on pin 9, so nothing should be keeping us from burning the tiny booter to it. It is of course after that to figure out the pin connection from 411 to LoRa and further details to adjust in the porting.
Since I’ve got only a 8 MHz or 12 MHz based tinybooter I guess it is not going to work plus there is this little fact I can’t get my hand on the mDot
… yet …
@ Justin - >>Now if only there was another way
Yes if only… :whistle:
Looking forward to a solution ;D
It would be awesome to have LLILUM working on the LoRa. Since it is a F411, it should be relatively easy. If anybody wants to give it a try, I would be happy to provide support. ;D
@ lt72 - Lorenzo, that is great news.
For everyone else, I sent an email to Lorenzo (the man behind Llilum) and said this:
[quote]Lorenzo, I wonder if you would mind reading the last page on this thread on the GHI message board.
We are talking about how cool it would be if we could get llilum running on an mDot LoRaWAN module.

You see his reply above. @ .Peter. did the French get you an mDot?
I will see if I can get anyone over at MultiTech interested.
@ terrence - read you email …
@ french is OotO :’(
