Bluetooth Blues!

[Yosser70]

I';ve been having a play with my AIOP v1.1. It';s got the MegaPirateNG V2.8 R3 firmware loaded and when plugged in via usd the GPS is working and shows when the board is tilted ect in flight planner so all good there. If I plug in the Bluetooth module before linking up to the computer it wont link up via USB, when I try to  connect it goes to the first bit after "waiting to connect" then just hangs on the first bit of mavlink and doesn';t go any further! Also if I connect up a battery to the AIOP and try to connect remotely to the blue tooth that doesn';t work either. I can see the Crius_BT in devices and get it to pair by putting the "0000" code in but it wont connect in flight planner, I';ve tried all the baud rate with no joy. Any ideas? Are there any special drivers I need on my laptop for the Bluetooth to work or am I missing something?

I gave up with BT and now have 3DR.

It would never connect, then did once and never again and that was using two different BT modules and despite the fact they the PC and laptop both paired fine with both of the modules.

That';s promising then! lol I know some people have got it working so it must be possible though!

LOL yeah some people do, but I wasn';t pulling my hair (what little remains) out over it. The 3DR just worked once set up, also the quad has another pointy antenna sticking out of it that makes it look really cool

Hi Yosser70 blue tooth will work but you might have to change some settings, first of all you need to make sure your blue tooth dongle is set to 115200bps if its the rctimer one then it should be pre set,
The next thing is which port are you connecting it to ? if you connect it to the FTDI port of the AIOP then it should work fine, but if your connecting to serial port 3 then you may have to set that port speed up in the megapirate sketch to 115200bps,
When you setup the blue tooth connection in windows it will make 2 new com ports make sure in the port properties they are set to 115200bps you will only be able to connect using one of the ports although you will see both in the planner if i remember right when i did it the lower port was the right one but if in doubt try both

Right got the BT connected to the AIO via the FTDI port. I';ve changed the rates to 115200bps on the two new com ports. Where do I check what the dongle is set to 115200? 

[Yosser70]

I';ve got these settings in Megapirate

#define SERIAL0_BAUD          115200   // Console port
#define SERIAL2_BAUD          38400   // GPS port
#define SERIAL3_BAUD          57600   // Telemetry (MAVLINK) port

Do I need to change any of these?

Setting the dongle up is a bit more complex and has to be done with a terminal program if its a rctimer one then it will be pre set but if its from some where else it maybe se to the default 9600bps,
Give it a try to see if you can connect now 

[Gaza07]

No because your connectiong through the FTDI your connecting through port 0 so it is already set correctly 

I';ve got these settings in Megapirate

#define SERIAL0_BAUD          115200   // Console port
#define SERIAL2_BAUD          38400   // GPS port
#define SERIAL3_BAUD          57600   // Telemetry (MAVLINK) port

OK thanks for the info I';ll have a play but think the 3DR route might be calling! lol

Well got it working!!! Unplugging the BT from the board and reconnecting it while it';s trying to get Mavlink did the trick, very odd but it';s a start :-)

I strike that at times after having the F/C connected via usb if i forget to disconnect the blue tooth module first

Just posted a poss fix here http://www.multi-rotor.co.uk/index.php?topic=3047.0 hope it helps :-)

What app are you using?

[firey1]

[Yosser70]

Ya that would be great mate, are you using Megapirate and a AIOP?

[firey1]

i use that on the crius board running megaP 2.9.1R7

cant send file through here so P/M me your email and ill send it through for you

[Yosser70]

Done that mate, cheers. Is 2.9 a stable firmware? Just wondering cos it';s not on the main download page yet.

[firey1]
