Very nice. Good to know the BT IPAQ Stereo driver for H5500 series will work on rx3715. I dont use BT headphone for music on my ipaq 3715. I use the good old wired stereo buds.
I do use the IPAQ BT to Activesync with my PC or to communicate with the BT GPS unit. I found for somereason if the connection is severe(ex. after either party went to sleep mode), I need to disable and reenable the BT function on ipaq or PC(sometimes both) to get them talk again. If I lose conection on the BT GPS unit, I only need to disable and reenable BT function on the ipaq only.
I found this little program called "MiniBT" to be quite useful to toggle BT on/off on the ipaq. It quite handy to toggle on/off with the use of a button by mapping.
PS: I found that MiniBT doesnt quite Work as advertised. I found another program that Actually works. It works quite different. It runs in the background and search of a particular "caption" on the "titlebar" and then turn on/off bluetooth according to the list you created. a bit complicated to setup. but it works.
