"It's not for a drone ;)
But apart from that, yes it works very nicely! The MPU9150 I had here has since gone to the bin !
I have BNO055 in 4 projects now"

"I have had more than 50 modules (433 MHz) from HK. I could get a few of them to connect to 3DR radios, some of them only sporadic, most of them no connection at all. The HK modules would happily connect with other HK modules.
I have my own developed…"

"Hi Jake,
yeah I know that is probably the proper way to do it, but I just can't stop thinking that "if"....
I had it compile ok, just had some strange problems with make.exe that is not compatible with the one it is made with....."

"I have sort of the same problem on my own boards (used in turbine powered modelplanes). I have a MS5611 on a board, and sometimes I see altitude drop because of pressure buildup inside the airframe (depends on the type of plane etc). I had a friend…"

"My thoughts exactly Jake!
I'm still struggling with the compile environment for the radios, I have it almost up and running (some problem with the version of make.exe I'm running (doing it all under windows)
Once I have enough spare time..."

"I have tried this with success (non flight, just in lab) on 2 x 3DR radios and a HM-TRP module on my own hardware.
Used this firmware (MPSiK 2.5)
Follow the description about setup etc from the RFD users guide (Node numbers etc)MPSiK V2.5…"

"Hi Tom,
I'm doing a writing on the stuff and will link here once it is done.
I do a lot of telemetry related stuff, first post (post #16) here shows some of it:

"Got it now (and as a bonus I found out some things about Mavlink ;)
I need to send the complete frame to the radio to get it to react:
FE 09 4E 01 01 00 00 00 00 00 02 03 51 04 03 1C 7F

The radio answers back with two frames:
FE 09 0A 33 44 A6 00…"

"I need to send the full frame to the radio in order to get it to respond anything. I'm using Sik 1.9 on both ends (3DR radio at one end (where I inject the message) and a Hope-RF in my own module in the remote end.
Independent of the remote radio is…"

"Ok, got it.
On the physical line, I need to send:
0xFE 0x09 0x4E 0x01 0x01 0x00 0x00 0x00 0x00 0x00 0x02 0x03 0x51 0x04 0x03 0x1C 0x7F

This will give the answer back:

Now just to…"

"Tom,
I have a feeling that I might not understand mavlink completely (is there some framing to take place/CRC etc?)...
I have set both the radios to:
