How to configure a HC-06 Bluetooth adapter for MultiWii


In this video I show how to easily configure your HC06 Bluetooth adapter to work with your Multiwii board.

This board may come set to the wrong baud speed for the Multiwii and in this video I show you how to change it using kit you probably already have in your toolkit.

Commands I used are:

AT+NAMEXXXXX to change the name of the board
AT+BAUD8 to change the baud rate to 115,200 for the MWC
AT+PIN2134 to change the pin number for pairing

Thanks for watching, please comment and subscribe.

Happy flying!

i dont get "OK" for sending "AT" 

what troubleshooting have you already tried?

Mine won't change Baud rate

Happy to help but please watch https://www.youtube.com/watch?v=olIqTiSJHIY and come back to me with more detail of what you've tried..
I have looked at every video that relates to my device, gone through many forums, didn't get much from the supplier, I have done my best to research but nothing has the solution. 

that a point, maybe I have to upgrade the frimware... mine is a keynote HM-10 bluetooth 4.0 v2. I have looked at forums specificly for HM-10 but the methods are no diffrent; the codes that is. it replys to 'AT+BAUD8' with 'Ok+Set:8' and yet I goto 115200 and it doesn't work, while 9600 does, its the same with all rates 

I'd look at using the ones we've played with here. There were a lot of changes to the specs of the later adapter and we've not used them. Sounds like you are doing the right things

What module would you recommend for Bluetooth for naze32 

We setup one in out Nase32 series - the answer is in there. Google 'Naze32 Bluetooth painless360' to find it.. Hope it helps.

will the Bluetooth M connect up with a ipad

sorted thanks

got my new bluetooth adaptors tonight i already have two but i decided i really need to start renaming them now...!!!! watched the clip and will be doing it in a minute.. thanks let you know how i get on...

Hi PL. I don't seem to be able to get my FTDI to work in Arduino. So far: - Running win 10, have tried also in win 8 compatibility mode. - Checked device manager. FTDI recognised, running fine baud rate 9600. - Solid green and flashing red led on BT module when wired up to FTDI. When I get to "Serial monitor" and type "AT" nothing happens? No "OK" Have tried all baud rates (You never know your luck) to no avail. Any ideas?

Swapped rx and tx? 

Have you tried all the baud rates in the program? +Painless360 Yes :'( Bugger. I notice that the FTDI is different from ours, best of luck.. 

thanks for the suggestion. Just tried with no luck. 

Did you find the problem ? I can't connect my HC-06 with ARDUINO. No "OK" when I type "AT" 

“Coco Racer” Pacaud Sorry mate no dice for me. Hope you can figure it out for the both of us 

I tried Arduino and putty, both didn't work, I'm gone :( If you are not using the 'real' FTDI chips then you are in for a world of pain. See the many many many answers already on the videos to see your options.. I have this one. And I read the comments but didn't find the thing about "real ftdi" : http://www.banggood.com/FT232RL-FTDI-USB-To-TTL-Serial-Converter-Adapter-Module-For-Arduino-p-917226.html 

“Coco Racer” Pacaud Ey mate. PL means not a Chinese clone. You and I my friend have a Chinese clone (Not a 'real' FTDI chip) Just means we have to open our wallets a little more. Clones can work but it is definitely hit and miss. Predominantly miss. 

Couldn't have said it better..   


Hi PL Will this be OK? https://nicegear.co.nz/cables-connectors/adafruit-ftdi-friend/ 

Maybe - we always use 'FTDI Basic' boards here.. 

Voila? https://nicegear.co.nz/electronics-gear/sparkfun-ftdi-breakout-5v/ 

That looks like a few we use here - best of luck with it and I hope that one isn't a fake. Happy flying! 

Thanks. For the price it better not be

ok:/ but 25€ the FTDI.... 

“Coco Racer” Pacaud Nope. That's $25 nzd. About €14. But I'm sure you'll get it cheaper than that. NZ tends to pay more for most things as we are at the "bottom of the earth"

This is so frustrating. I have followed your every step and can't even get the first command to work, pleas watch my 17sec vid and help.

I know you will ask what troubleshooting have I done, I have tried all Baud rates and all board types, the only reason I got the BT for the Naze32 was because of your videos, if it all works it would be great! 

Swapped Rx and Rx cables round? If that Durand work then the FTDI or BT module need checking.. 

yep, don that, I think I might have a duff Bluetooth board.

superuuu. maacha

I get no choice of port when I connect, the border is seen but no drivers are there. 

+Brian Tapp Happy to help but please watch https://www.youtube.com/watch?v=olIqTiSJHIY and come back to me with more detail of what you've tried..

Very good video, very easy to understand even for those of us who are not pros :) Thank you for fixing this problem for me!

what processor what board and what programmer do i use i cant find info anywhere 

You don't need to set that, the board should come with the software on it you need. The board and CPU selection has no affect on how the Serial Monitor works - have you tried it? 

I see that it picked it up automatically. The problem is none of the AT commands are working. it's set at 5600 and is working but I cannot configure it using Arduino

Hi Painless, I'm trying to connect HC-06 Blutooth adapter to Multiwii, initially to changes buad rate, I connected via FTDi adapter to my PC. My PC detects the FTDI as COM6 and HC-06 as COM7, there was a blinking light in HC-06, Once I open Arduino and select COM7 and open serial monitor, the blinking light becomes solid light in HC-06 with buadrate 9600 and "no end line". If I send AT, there is no response HC-06. My connectioned HC-06 to FTDI is GND to GND, 5V to VCC, RX to TX, TX to RX. I tried even different buad to connect but no response. I'm able to detect the blutooth signal in my mobile. Please help me. 

Disable the BT module on the PC and use the FTDI com port.... Best of luck! 

Did the same and used COM6 and no response after sending"AT" , the bluetooth module just blinks. Tried with 9600 and different buad rate too. 

I'd go back to the vendor then, best of luck!


Hi, I'm running into the same problem as others... My FTDI is working fine (I can use it to configure a minimOSD board, so that proves it's working), and I can connect to the HC-06 fine via BT from my PC, phone, etc, but no serial response of any sort back from the HC-06. Yes I've done all the basic troubleshooting... checked drivers, swapped lines, etc, etc. Any new thoughts on this? This is making me feel like some sort of noob!!! 

Connecting to the BT adapter using the phone proves very little. In my experience it's the connection from the BT to FC that causes the problems. You need to confirm that the baud rate is correct for the FC and then make sure you have the tx/rx lines connected.Best of luck.

Good work! thank you so much ;)

Hello. First i'd like to say that your videos are well organized and easy to follow, thank you. I'm having trouble communicating to my HC-06. The one i have doesnt need an adapter like yours. It connects directly to the my MW328p. It pairs with my galaxy phone but it does not show any Parameters. Ez Gui App tells me "no data received". I've follwed this video ( https://www.youtube.com/watch?v=Uwn5DGf1bko)  but nothing works thus far. Can you help me? 

What troubleshooting have you done? Did you connect it to the PC to configure it? 

I have tries different apps on my phone. Switched the tx and rx cables round on the FC and module. I've tried communicating with serial port in arduino type all the commands but no response from Hc06. Nothing is working except it pairs with my galaxy phone.  

And have you setup the baud speed? 

Should I have done so in the PC or in arduino?  

In Arduino software - see 1:17 in the video for the answer to your question.

Best of luck.

The first tutorial i can follow congradultations! :)

Hi ! i'll do the same wiring diagram than you and the AT Commands not responding with my HC-06 BT module .... CAN YOU HELP ME ??? 

Why are you shouting? What troubleshooting have you done? 

i wiring like you show in the video but i have only a red led blinking when i plug it with the FTDI... No response with AT commands... 

So have you swapped the rx and tx cable? Tried every baud rate? Checked that the FTDI driver is loaded properly and you can see it in device manager? ? 

My FTDI module works fine, i already load Multiwii 2.4 in my MultiWii v2.5 card (and my QuadX works fine). 

My Wiring Diagram: 
it's OK ? 

With Arduino Software : Settings for card must be in 3.3v or 5v ? 

I will trying every baudrate this evening... 

Thanks for all ;) 

Try a different version of the Arduino program - if that fails then it maybe that the BT module is broken.. 

Best of luck

Got up and running with walk through. Cheers!

HEY, i connect every tink and i dont get the at ok, can u help me? 

What troubleshooting have you already tried? 

i try to put rx to rx and tx to tx, i try in reverse and nothing, the bord is on but no signal from the pc 

What settings do you have in the Arduino serial monitor program?

Do I need to use an FTDI... or can I use a USBasp? .. or can I talk thru a raspberry pi.. or arduino board to change the BAUD? That is All I think I need to do???? 


You can get them from lots of places, search for 'FTDI Basic adapter'. You can use other boards but I don't. 



I guess I could have used the serial port on my system and powered from another source... DUH But I got the FTDI it should be a useful tool anyway

What if you don't get any feedback when type AT and send 

What troubleshooting have you tried so far? 

It worked in the Arduino software with an ftdi and 9600 8 n 1 no cr/ln. I tried another ttl usb adapter  and that didnt work on windows and mac.  

On MAC you can get a tool called Serial Tools that works too. There is also Putty on 

Have you tried all of the baud rates? 

Who me? I got it working.  

i got one but it won't respond any thing  

What are your settings? Baud etc What exactly did you get? Model? What OS? What kind of serial software?

Great vid worked like a charm.
just worked for me thanks great informative clip

I have the HobbyKing ATMega2650 board and I have been struggling to connect the bluetooth module for days now. 

You say the default baud rate for MultiWii is 115,200.  But, I have MegapirateNG (3.1.5-R2) loaded on this board...   

Have you ever set up a BT board with Megapirate?  Do you know what the default baud rate is for MP?  I cannot even get my computer to handshake with the BT board.  I was considering trying multiple baud rates, but that could take a while--I was hoping you might have the answer! 

Thank you for your videos.  They are a ton of help for those of us who are getting into this great hobby but have little experience. 

No worries, I got it to work!  The key change was me powering the bluetooth off of the BEC instead of the main board.  I may have had too many peripherals plugged into the board (GPS, Rx, etc).  I got Mission Planner up and running over bluetooth.

HI! I'm trying to configure my BT module by AT COMMANDS whit Arduino. I dont have a FTDI board as we seen in the video, but I have a USB to UART board (http://www.ebay.es/itm/130683943875?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649&clk_rvr_id=683556886088). I connect my BT module with this board (Tx to RX, RX to TX, Vcc to Vcc and Gnd to Gnd). Then I connect de USB to UART board to the PC and i try to send AT commands with Arduino but i have no response...:( Any idea? 

It only worked with ftdi for me. Another adapter didn't work.  

Yep, go FTDI. It's not worth the hassle..

Hi, Do you also have a video about how to set up and connect the MinimOSD to the Crius MultiWii V2.5? I am dealing around with it now for several days, but I have not got it working so far. Thank you very much for all your other videos! Very helpful for me, very good explained... 

Hi Thomas, my MinimOSD is on it's way and once I've got it sorted I'll post a video. Looks like there are a few steps to get it running and I'm not clear on any code changes needed on the main MWC to get it running. Watch this space. 

Yes, I will let you know or will post a video on how I did it. Thanks...  

Awesome! Did you have to change the code in the main board? Which connector on the Cirus board did it go into? Very interested in your method and results. Thanks for posting.. 

No it is not working yet. I have the video signal from my cam but no OSD overlay. I am playing around with this code https://code.google.com/p/rush-osd-development/ but i was not successful. Maybe you can give me a hint how to set it up and how to connect the MinimOSD to a MultiWii. When i connect the MinimOSD to the PC everything looks fine,  but i cant get an overlay. :(

Hi Thomas, my understanding is that the minimOSD is expecting to see the MAVLink data coming out of the telemetry port on the APM flight controller. 

From what I can read (haven't got mine yet) you only get the OSD display active when the board gets this input. I'm not sure if the 'basic' Cirus SE 2.0/2.5 board send out this MAVLink data to fire up the OSD.. I need to get mine to play with.. 

That's possible, looking forward to your experiences ;-)  

I've got it working - finally! Tricky little bugger but once you've got a few things figured out it works a treat. I'm uploading a video as I type that should cover what you need. Awesome OSD for less than £10!Happy flying! 

I just saw and followed your step by step guide... Great thank you!!

Thank you very much for the video, it helped me configured the module. I still have issue with Windows 7 connection. The OS discovers the BT device, installed the drivers of the uart but under “Device control” it indicates “Unknown Device Operation” and doesn't let to connect to it. Any idea? 

Thank you so much for this. I ended up getting luck with mine. I used the Ublox software and it eventually recognized it and I was able to get it working. I didn't know you could use the Arduino IDE.
