Help Bluetooth not staying on

[mted558]

I'm having an issue with the Bluetooth on my S6 shutting off by itself. I've tried clearing the cache, some other things that Samsung suggested, all except for a factory reset which I'm hesitant to do. It will work for a week or so then out of the blue I'll turn it on and it will shut off after about 4-5 seconds. I'm trying to sync my Fitbit which is where my issue is. I don't have anything else I use the Bluetooth for so not sure if it's the Fitbit or not but I spoke with them and it didn't look like that was the issue, it's the Bluetooth itself. Does anyone have any suggestions other than a factor reset? Thanks for any help
