Hi everyone, here’s the latest state of codec2-FreeDATA: https://github.com/DJ2LS/codec2-FreeDATA/blob/main/documentation/codec2-FreeDATA_05.09.2021_11_29_05.mp4?raw=true
The project is moving forward - step by step - but still a lot of work to do. But as you can already see, I integrated the data module into the application, so no additional software is needed for sending data. All application settings are visible on the main screen. No hidden settings. Just those who are visible and necessary. Lets see If I can continue with this idea. As soon as its possible to send data (which is already working, but unstable) and the GUI + TNC is in a more stable state, I will make another announcement. Have a good time!
