Bluetooth Attachment

[snoopy60]

windows 8 on my tablet

[pandimus]

Mine also is immediate...

[cosmith71]

Nope. During the upload, the screen should go off, and the red light should flash. When it's over it should come back up and start running.

[snoopy60]

I'd like to see if anyone else has any thoughts but I can try using the cable again to see if it does the same thing. I can always switch to my desktop using win 7 now that I have blue tooth. Again, everything else seems to be perfect

[cosmith71]

I use Windows 8.1 with no problems.

[snoopy60]

screen on the head unit (reef angel +) goes off, red light flashes (and blue light on the BT attachment goes on). when upload finished, blue light goes off, red light stops blinking but screen doesn't come back on until I detach the BT and plug it back in.

[snoopy60]

screen goes off on head unit (RA+), red light starts flashing, blue light on BT goes on. when upload finished, blue light goes off, red light stops flashing but screen doesn't come back on unit I detach and reconnect BT

[snoopy60]

wonder if I ought to reinstall the software?

Any thoughts on what I should try or what might be causing this?

[Sacohen]

Reinstalling can never hurt.

I'd be interested in seeing what it does on your Windows 7 system.

[cosmith71]

Did you replace the rxtxSerial.dll file?

[Sacohen]

I believe he said he did that earlier.

[pandimus]

Does it lock up after up load? Can you do a reset command?

[snoopy60]

replaced the dll.

after upload I have to disconnect the BT widget from the head unit, then it accepts the upload and works perfectly.

How do I do a "reset command." and will that help diagnose the issue?

[pandimus]

I use the reset, from my reef angel app. It always gives an error but does reset it..

Hi,

Received my Bluetooth attachment and got it working pretty quickly.

I had a question though. Is it normal for the actual software upload to be much slower over bluetooth?

With a direct connection it takes around 6 seconds, with bluetooth it is more like 40 seconds.

Not a big deal but I just wondered.

[rimai]

Yeah, I think it is the overhead of the bluetooth connection, but I may be wrong. I never really dug deep to find out.

Question for ya rimai.....does the BT modual need to be an rn-41 or can any old arduino bt modual work?

[rimai]

I've had issues with different modules.

[AlanM]

I haven't uploaded new code to my RA for a while but went to do it tonight and discovered that my bluetooth attachment wasn't talking to Win 7 anymore even though it still showed RNBT-41FC device listed. I removed the device and went to re-add it, and it fails each time. I disconnected the bluetooth from the head unit, reconnected and tried to re-add, but it failed. I rebooted the computer and it still failed.

It gives me error code 0x80004005 which probably means nothing, but are there tips folks can give to get it to connect when it insists on not connecting?

[cosmith71]

Delete the driver, reboot, and then try.

[AlanM]

Worked! Thanks for the suggestion. I pulled the dongle, rebooted, made sure no bluetooth was installed, then inserted the dongle and re-connected and it works now. I uploaded the code with DDNS enabled. I also repositioned the module a bit, but I don't know if that helped or not. It's in my basement and my computer is upstairs. Between the last time I reprogrammed and now I have drywalled the ceiling of my basement between the computer and the attachment which may drop the signal strength too.

[cosmith71]

Could be. Poor signal strength does all kinds of funny things to these.

[AlanM]

Hah, worked once, uploaded code. Made a small change, and after that the arduino client reports that the com port is gone. Deleting and adding this time doesn't do it an now I can't even get the com ports to come back. I bet it's a range thing. Hmm.

[cosmith71]

I used a USB extension cable to move my bluetooth dongle closer to the aquarium and farther away from my computer. It's much more consistent now.

Colin, I have one of those that I used to run with my Apex feeder. It's even still run from the controller position upstairs to the tank right by my computer. How do you use it with your bluetooth connector?

Edit: Duh, I get it. You put the bluetooth dongle at the end of the extension with the USB end attached to your computer, not the bluetooth attachment from the RA somehow nearer the computer.

Plug it in, move your blue tooth adaptet closer to reef angel

Hah, yep, thanks. I realized that just now.

[AlanM]

Suggestion works. I had a 10 foot extension cable that added just enough signal to make it pretty reliable. Thanks.

[cosmith71]

Glad you figured it out.

[psirex]

How much and where can I get 1?
