Hi all. I hope everyone is doing well. Subject is pretty accurate. I'm wondering if there is a way to tell how much data is being transferred--as well as how fast or slow--between my Mac and iPhone and any of my blue-tooth devices. Somebody on an email list recently suggested low data as a possible cause for me being unable to connect my NLS eReader successfully via blue-tooth or USB to my Mac and/or iPhone. In addition, I attempted to connect my blue-tooth headset to my Mac a couple days ago and was unable to do so. This has worked flawlessly before. I had just fully charged the headset prior to this attempt. Any help greatly appreciated. I guess I am also curious to know how many blue-tooth devices can be connected/in use at a given time. A neighbor and I were sharing a single wi-fi connection for several years, but he recently got his own wi-fi so we don't need to share anymore.
