1. Let me first explain how it works in our case. All code written for mysensors.org should be GPL v2 or higher. If you contribute code to mysensors.org you have to agree on our CLA. If you don't agree with the CLA you should not create a pull request. According to our CLA you still own the copyright to all code you submit (you may for example submit your code to another site under whatever license you like) but you also give mysensors.org the right to release the code under any other license.

It is not uncommon that organisations impose you to sign CLA:s. Even if you contribute code to FSF (Free Software foundation) you need to sign a CLA. One of the reasons is that the organisation in the future more easily can adapt to changes. Another example is the Linux Kernal that is released under GNU GPL v2, in order to change to GNU GPL v3 they whould need a written statement for all contibuting developers, since they didn't sign any CLA:s.

1. We will use GNU GPL v2 or higher as license for all code written for mysensors.org in the repos.

@Bmlsx Thanks! I will try it out

@kellyjelly It's no problem having more than one sensor per radio unit. Each sensor must have a unique childId per radio unit.

Each node holds a table with possible routing candidates, It will try all candidates in the same order each time (if the first one is down the next one is tried and so on...). The message is ack:ed so that the sender knows that the gateway received the value.

(Henrik, correct me if I'm wrong)

OK, there where a few glitches in the Makefile, you can update it now.

Could this we worth looking at?

Is it possible to split the encoded messages in many parts and send them using the RF24 library (overhead?)

@andriej
Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch.

We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)
