Hello old grumpy man here who is trying to find out how to fing out what the use like wifi or bluetooth .I now my bfh-155 denver brand watch is using bluetooth and sadly on a smrtphone without internet,so this is the only watch that do works for 90%. My led controller is no idea. and i have no idea how to find that out. Yes i do read but soon get lost in what to use and/or where to get it. So my asking is is there a kind of for dummies guide on this subjects ? I grow more frustrated every day every thing need a smartphon and windows desktop but the never say what version it need. got android 4,4 and windows 2000
Greetings Jan
