A few more points. I believe I have the correct drivers for the board. The device manager shows the device and shows the correct com port. The baud rates match. I was able to calibrate the acc and I also calibrated the radio. Let me know if you have any questions. I didn't change any of the xmtr settings that came with the sketch I used. I'm not sure where to get a clean sketch.
Im seriously about to pull my hair out...I managed to load the sketch with arduino onto my Multiwii..actually got my wingui to the the board and was able to see all the parameters and that the board was working (turned it saw the horizon, Yaw...etc changing. I had all my settings on Com 9..However now i am unable to see it in the wingui..Its telling me that I have the wrong Com port when they are all on the same Com 9 but its not communicating with the board..HELP!!
Trev, welcome to the wonderful world of MW..... so a few Qs4U......do you have the right drivers for the board... have you had the board working at all....... is it in a craft or is it just by its lonesome near the computer (as you seem to be new on 1 point)....have you been into the control panel device manager to see if the computer is seeing it and you have set the right baud rate for the board (115200) as the default is 9600....have you checked another USB cable as sometimes these are the problem.....IF you have the right drivers and everything is ok and you can connect to the board can you calibrate the accs and mag........ if you are lost then there is a fair bit of info in the purple tab above..... I have put a link into a great set up vid (everything you need to know) plus there is a before you ask sheet which runs through a few things to check so if you need to ask us for help (and thats what we do) it can hopefully fast track the pace as all have been there and done that and just want the hair to stay on our head...... also on my youtube channel I have a few vids on how to set up these boards etc ...... moochasas ...... I bet its something really simple...
The board is in a craft(450) but is not hooked up to anything yet..it had been working previously. The drivers were installed and i can see it in my device manager. Baud rate is set correctly to 115200 and I did have to switch usb cables cuz the one that came with it was not working. I did have wingui working and I could see everything perfectly and calibrated the acc and Mag. It just keeps telling me my coms are not set correctly when they are all (device manager, arduino and wingui) tell me I'm on com 9...the purple tab has been extremely helpful...i just can't figure out why all of a sudden it can't connect...
Great info.... tells me a lot thanks...... I would do 3 things........ reload the drivers for the board....try another computer .... clear the eprom and reload the sketch.......the process of elimination..... lets us know how you got on....
Something that flummoxed me was that the board must be connected to the usb port before the GUI is opened. If it's done in the reverse order, it will not connect. If you already knew this ignore me, I have my own problems. :)
Tre ... you could have a computer issue ... remove other USB devices and try using a different USB port. A reason for the erratic behavior is that the board is not getting enough power or the USB port has memory conflicts ..**** 9 means your computer has assigned all the lower COM ports to other ports...
Maj, have you got the telemetry to work on your taranis with this board....... I have got the RSSI and volts to work but I havent got the LAT/LON for the GPS...... I am fairly certain that you have to run a sep GPS through the FRSKY hub .... but I thought we maybe able to get the GPS info out of the MWpro board back to RX and back to the radio......
I dont know gordo... some of the frsky information comes back via the RX while other information doesnt, it has to be connected into the hub. But I would have thought that the information from the MW board could have be transferred back to the radio..... I wouldnt have though you would have to have another GPS unit to connect to the hub but its appearing that way....... I have done a bit of research but nothing confirmed yet....
I'm not sure but I think the sensor hub is set up to take the raw data from the GPS. The sensor hub will send it to the TX. FrSky maks a GPS but I'm with you - why two? That's why I was wondering if you could just split the feed out of the ublox and plug it into the sensor hub to get it to the taranis.
Now your wheels are turning.... and that is my thinking....... if this MWFCB has all the bells and whistles why cant all that info be sent back to the radio..... you would think (hope) that its just not a protocol that Frsky uses just to sell their own gear....... I have managed to download off the RCgroups forum a multiwii frsky sketch in 2.3 navi BUT if requires an RS232 to TTL converter and currently I am at the point where I am researching why and what that does in the grand scheme of things...... people on the forum have got the frsky telemetry to work using a Multiwii FCB but its not with this board..... so the reading, thinking, wondering continues.......
I should have mentioned..... its shouldnt be that hard in this day and age but like most things I have found in this hobby....... its not plug-n-play..... and just to finish I was wondering if I had to run 2 GPSs which I happen to have a spare MTK or 2 that wouldnt be a bad think.... just in case the copter went down you would have a back up.........
Sure, you could use two, but that's more weight and not an elegant solution. It's similar with the rtfhawk. The hawk's power supply has the amp meter on it, and I have no way to get it's data to the taranis with the X8R. It could work with the D8R but I need 14 of the 16 channels so the D8R is out. It is possible to use the sensor hub with the X8R through the vario, but when you do, guess which data won't pass through? That's right - amps. And also, no way to pass the GPS data to the taranis without a special device.
Came back from flying ... no not me doing the flying ... me sitting inside a heli then a single prop. Anywhoo .. I do not have the FrSky receivers that are Taranis friendly . all my copter use the FlySky TGY receivers ... and the only FRSky I have is staring at me in the face. Telemetry is via EZGUI and for long ranges, the 3DR works okay via OTG cable ... if and when I finally get my head over the FVP thinngy, I will have OSD via Mimin ... Not looking to use the FrSky too much as long range will probably be via OpenLRS ... which has more than 100mW power.
So Maj.... a real heli and plane...... details....... and vids??..... gordo...... I will try just hooking up the MTK to the frsky RX and see what happens..... gotta feeling that nothing will eventuate..... and I dont mind running 2 GPS units ....... great if we do the EML (emergency land)..... we may have a backup copter finder....
Yep ... got the vids and will be editng after the apple picking tomorrow ... Took up the SlowStick today with a 10 yr old flying buddy ... I'm so glad to be able to get him to fly if only for a few minutes (me on the stick most of the time) ... never had that chance when I was young but I always wanted to learn how to fly RC models.
My young ones are 22 and 25....... but their eyes do light up when they come with me..... my son has had a go and my daughter wants to learn but every time I go they are too busy...... So went up in a real copter. They are fantastic ....... my wife and kids bought me a flight in one a few years ago for a birthday present and I got to fly it..... awesome....
Great unit, with all the features you need for your MC. And the price is awsome, so normally, you cannot make a mistke on buying this unit.If you buy this features in europe, you will pay 3 times as much or more. For the HK price, you get at least the gps module ( sometimes ) but not incluiding the board, wich has a big and powerfull processor also. So another time, where HK makes our hobby affordable. This is what the MC-Flyers need to upgrade their machines.

Received the board today from HobbyKing .
After reading about all the broken Micro USB connectors on other FC like the Crius AIOP , I had a good look at the USB connector BEFORE connecting anything.
The micro USB connector is soldered to the board at the rear corners and also has 2 tabs half way down the sides.
Close inspection reveals that it does NOT have a lot of solder to hold it in place and YES it is likely to break off without some extra solder.
The side tabs do not appear to have been well soldered, my guess, surface mount automated soldering has not applied sufficient heat to get the solder flowing well around the tabs which are part of the larger metal connector shell, using a fine tipped soldering iron, care is required specially on the side near the pin headers, re soldered the metal tabs and also the rear corners of the connector, I don't think it will come off now.
Do keep in mind that is a very small connector and the cable can be used to apply sufficient leverage to rip it clean off the board, no amount of extra solder will prevent that, so be real careful not to apply sideways forces to the cable when plugged into the board.
The quality of the board, the soldering of all the other components, I can't fault it, all looks excellent.
Lots of information now in the files tab for the product at HobbyKing.
I connected the GPS to Serial 2, and the flashing LED
