Did some experiments with Tizen ( operating system Samsung ) and Peanut. The Peanut application runs natively on the Watch, no phone needed. I having a lot of issues with the sound code. Sometimes the soundbuffer is filled an the device completely hangs.. Maybe I will continue when a new Tizen version comes out and all bugs are solved.
Wow! Today I received the new ZUM radio! What a nice device! The size is equal to a ThumbDV/DVStick30 or an USB stick. The device comes in a nice box and antenna is included. In the upcoming days I will test the device with BlueDV Windows.
Upcoming Peanut Windows version works with your soundcard. Will be available soon. ( hope before 15 feb 2019 )
