A ping is any measurable packet/signal. You never pinged an IP address? The term 'ping' originates from early sonar days. Yup, found it: static void __attribute__((unused)) hubsan_build_bind_packet(uint8_t bind_state) { static uint8_t handshake_counter; if(phase < BIND_7) handshake_counter = 0; mems...

Is that code pretty generic for most RC transmitters? Namely, do you think a Devo7 would accept the firmware as is? .... Read that page, there's even a nice graphic on top of it that explains what this project does, and where in a chain of equipment it's used. There is NOTHING that will run on your...

Also, is this just the Hubsan version of the same code? https://github.com/silver13/hubsan-flysky-protocol I am thinking these 2 URLs contain everything I need to edit the protocol and get my ping. Thats what they look like but, these are also famous last words I have used before right before I bric...

https://github.com/pascallanger/DIY-Multiprotocol-TX-Module The code is the best "documentation" you'll find for the various RC protocols. Is that code pretty generic for most RC transmitters? Namely, do you think a Devo7 would accept the firmware as is? I had found that but was not 100% ...

Either you write one from scratch, you port an existing one to that hardware, or... you change your radio for one that supports what you want.

Do you have a link to an existing one?

Is there a DeviationTx alternative? the more bare bones, the better.

Can you elaborate?

I am an RC n00b, but not a computer n00b.
I am trying to get/receive a ping (test packet/tracer packet) from a cheap little Hubsan X5 on FlySky.
I have a Devon7 (not the E) and a UP02 module for uploading firmware.
Just proof of concept, thats all.

Is OpenTx the right tool for the job?

AFAIK they're completely different, the 7 is super simple hardware with pretty much nothing interesting in to play with, e.g. segment-based LCD. is there another project like DeviationTx that will provide access to the FlySky protocol (and upload firmware) that doesn't have screen requirements? I h...

I 'think' that the only reason the Devo7 is unsupported is due to the lack of USB interface. I do have a UP02 adapter http://www.ebay.com/itm/282237376830?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT ready to go Is this the only missing piece of the puzzle? The documentation is unc...

I have a Devo7 http://www.deviationtx.com/wiki/get_started_with_deviationtx in bold print it clearly states 'Devo7 not supported' :( #1 What is the difference between the Devo7 and the Devo7e? (whats missing) #2 Can a Devo7 be modified to utilize DeviationTx? I'm not wild about spending $260 just to...

There is code in Multi that receives telemetry when the protocol is set to HUBSAN, and passes the data on, in FrSky telemetry format, to the Tx. You would need to be using a Tx that is running open source firmware for that telemetry data to be processed. Mike. Thank you very much! if there are any ...

I think the MULTI 4-in-1 module will do this, see: https://www.rcgroups.com/forums/showthread.php?2165676-DIY-Multiprotocol-TX-Module . Mike. Thats surely is coming up but from what I read, that addresses being able to sync with various devices using FlySky. Either I missed something or it did not ...

I have a cheap little Hubsan X4 that I would like to receive data 'from it'. When the device is powered and then sync'ed, the receiver beeps indicating synchronization. That mean that quad is tx'ing some packet back to that receiver. I don't need full OSD, I only need an occasional tracer packet fro...

I am building custom light weight air crafts.

I have no clue what the final configuration will be.

No, I am NOT trying to hotwire a Walkera or any other commercial brand.

Set #1 is to chop weight everywhere.

my bad..

EVERY gram counts when you are pushing efficiency. I'm actually watching my 1/10th of grams. every single capacitor is evaluated for absolute necessity. Do I really need landing gear? Nope Can we mount that motor with 3 screws and not 4? Yep. also, shitty plastic props rattle (harmonics) which creat...

YES!!!!!

I need to produce my own props and frames. (in another life, I am a fiberglass tech) All of the RC suppliers produce props for racing, speed and bite. I need maximum efficiency and ultra lightweight. are there any advanced molding plastics designed for this purpose? cheap plastics suck with harmonic...

I just got mission planner compiled for Linux. It was a little painful because my Qt5 installation was bare. There are a few modules you need to install that are not on the list in their documentation. Here is a repo dump and rpm query for Qt5 packages. It will save somebody a lot of time. # zypper ...

I am trying to understand the math/mechanics behind efficiency (not so much performance) I have a little hubsan X4 that comes a 380mah, 3.7 volt, 4wh battery (I do not have the c rating) that runs for 5 min before it teeters out I purchased some replacement tri blade props and the flight time reduce...

I was horribly mistaken. the mac controller on wifi is ASIC. you're not getting to that radio to play another tune. http://www.labs.hpe.com/personal/Jean_Tourrilhes/Linux/Linux.Wireless.wlan.html Plan B I have a Devo 7 from a Walkera. It's got no data port but I suppose that can be changed. I will d...

Both are digital. Just download the datasheet of the chip. But if it was that easy to replicate signals from completely different proprietary transmission schemes we wouldn't need SDRs to generate arbitrary RF signals nor modules that actually include all the common RC RF chips to control multiple ...

I am suspicious that FlySky is actually digital.

wifi uses 802.11, but thats not the only tune that radio will play.
the hubsan x4 uses FLySky
one is digital, the other is analog.
Digital will do analog very easily.

I am pretty sure this is what I need but its for a particular microcontroller, not x86
https://github.com/mkschreder/martink/b ... nrf24l01.c

I'm a little rusty on my reverse engineering microcontroller code for radios.

I'm really trying to use onboard/existing technologies.
I could run to radio shack and buy a new transmitter as well.
I can't see why I would need a 3rd radio on my laptop.

I'll be getting to building my own radio soon enough.
I just want to get some logic running across the radio waves

My PC has a perfect 2.4ghz radio on it! my wifi even has adjustments for db gain and other filters to improve transmission and reception quality. is there any reason why I can't just capture (or wrapper) the /dev/radio0 from my PC wifi, throw 802.11 out the window, and teach it FlySky? Is there a Fl...
