sunny boy blue tooth problems

Micky,

Good to hear you got it sorted

Yes, another learning point here - Cheapo Bluetooth (eBay £4.99 specials) can be CR@P! (what did you expect for a fiver?)

I have invested in a Parani UD100 (cost me £25+vat  from Expansys - just checked - they've gone UP ). It is a bit bigger than the cheaper types, and even has a screw-on stub antenna.

The difference is amazing. I can now reach my SMA 4000TL from right across my house (several brick walls), where the signal gave up before, at well under half the distance. No changes made to the inverter.

I have experienced no problems myself with Windows 7 and Bluetooth. Maybe that's because i'm not shooting for the moon.

To be fair i bought some £1 bluetooth adapters from Ebay and they work fine on my pc and my laptop.

My pc requires the signal to work through quite a few walls and ceilings as well so it is probably pot luck with them.

Gents, I followed all your advise.  I had a little no-name cheapo Chinese BT adapter (with a Dafron? driver) and no end of trouble.  Sometimes it would connect, sometimes it would not.  Recently, I went 3 days w/o any access.  Being a cheap-skate, I followed Micky's recommendation and bought the Belkin adapter for £5.  Excuse me but what a CR*P.  The installation was just painful.  And when the WIDCOM driver was finally there - nothing.  It would receive the SB but it was not strong enough to send to it.  So I bit the bullet and coughed up £30 to get the Parani.  Install was a dream.  It saw the SB but initially would not talk to it.  I eventually removed the traffic encryption from the Security profile and it got going.  Got 3 bars (good) for the first time.  Sorted, I thought.  Wrong.  Badly wrong.  After I returned after 1hr or so to my desktop to check production, the connection had dropped.  It was impossible to restore the connection.  In fact, my Sunny Beam was bleeping coz it had lost all comms.  The BT adapter in the SB was dead, sulking.  I waited to sundown, then rebooted the SB.  Within minutes of running the Parani, same again - SB cut the comms and sulked.  Rebooted the SB again and now comms have been up for, hm, 15 mins.  Laurence, have you made similar experiences?  Is there something I need to tweak?

The Toshiba driver behaves very oddly.  When I double-click on the SB icon, it will initially establish a connection and the Toshiba icon will show some sort of wires being crossed; the tray BT icon goes green.  After a while, while the tray icon remains green and it seems that SunnyExplorer still maintains comms, the crossed wires disappear from the Toshiba window and the context menu suggest that I should connect (and not disconnect).  Very odd.

Strike that.  Who needs a Toshiba driver when Microsoft's own Generic Bluetooth Driver seems perfectly up to the job.  And it doesn't Oh, how I wish it was better out.  Well, see how this goes for a few hours...

Had the PC running Sunny Explorer all day w/o a hitch - except that ... half way through the day, my Sunny Beam lost all comms to the SB4000.  No amount of tinkering would bring it back until ... I quit Sunny Explorer.  Sunny Beam came back immediately.
