All the code I can see looks to have the same license? At least it's got the same header as the others. I'm not experienced in such matters. I was just going to drop the GPLv3 in LICENSE in the root but I'm not sure if that is safe. |

It may be not a bad idea to use a permissive license that allows UEi to freely use the open source code in their multimeters. For one thing, it may have the effect that people such as EEVBLOG forum members start getting better multimeters. With a permissive license, any or every multimeter company could use parts of our 121GW code if they want. Also, if we implement some new Bluetooth communications protocols for the 121GW and the same protocol starts appearing in many other multimeters, is that a bad thing? There are aspects of GPL that are impossible for many companies to live with in their products. GPL does do a bit of "You have to do exactly what I tell you to do" and that is not exactly free. Is the point of the code to allow 121GW owners to reprogram their meters which only needs a permissive license, or are there other goals in mind that require a GPL license? |

Shame on me, guys, I don't have free time at the moment to work on this. Hope to get back in a few weeks. Sorry :(. I also have to learn a lot since my experience with MCU is very limited. |

With a GPL license, UEI and other companies can still use the code. However, they need to share their improvements to the code, which is just fair. Therefore, I strongly support the use of a GPL license for this. |
