JJrc345 drones as gift in return for protocol.

And finally packet period.

Phewww!! man I hope I got all that together in a way that's easy for you to understand. Thank you for your very well written directions and let me know how I did with following them. Chris

Which channels have valid data? 71,73, any other ones? Also, when in bound mode without any stick movements, do any of the packets permanently change? We'll look at the data and get back at you. Thank you for staying up late for us, there is already lot's of thing for us to see

The channel that displays almost every time at the point of binding is 71. I saw a 73 only a few times out of many. And I saw 72 one time. The packets on 71 are the same every time it lands on 71 and they don't change from there. I don't know if that helps. But I will redo any step that you request. And by the way I stay up this late more often than I should anyway. Night owl all the way. May I ask what country you are in. I'm just curious. this is the most fascinating and technical thing I have ever done with deviationtx by the way and I thank you so much. Please let me know how I can help the most. Chris

once bound and finishing the first scan, press ENT again to continue scanning. The TX should then stop on the next valid channel. you can repeat this any time you like. But from your bind information it is likely that only channels 71 and 73 are used. Also, could you rerun the interval test once for every valid channel please? To do so, set get intel in protocol options to 20, then go to the channel before the one used (70), then start scanning (it will stop on 71 and measure intervals. Then do the same for 73 and any other channel you think is used. Goebish is working on a first implementation for deviation already.

edit: also we now need to see which packets are affected by buttons. Check if any of the buttons (I don't know the features of your drone) has an effect on any packets. Note that you pushing activating two functions on the tx may have a combined effect on a single packet (for your information: each button may set a so called flag, and a couple of flags can be carried in a single packet).

edit 2: one more thing: also check how packets are affected by pressing the trim buttons.

Here's what I got. I did the bind scan four times in a row by pressing enter each time. Here are the results in order.

Here are the results of the 20 interval tests for valid channels. In order.

The transmitter has a button which toggles between 3 angle modes. Yes it does have an effect each time and changing the third line of packets. here they are in order.

1 click Beginner mode



2 click intermediate mode


3 click expert mode

And finally yes the trim buttons do have an effect on the third line of packets with each click. Do you need me to photograph the effect from clicking trim buttons. And how many times in each direction would you like. You guys are awesome. I hope I'm doing a good job and accommodating your requests. Chris

I scanned with channel 63 several times and came up with this each time.

Yes you are doing a great job. Just tell us which trim button affects which packt and what the minimum and maximum values are, that should be sufficient.

edit: we are also still missing throttle stick, you didn't record that yet. We are getting very close.

Here are the results of the maximum and minimum trim values. Each changed the third line of packets.

Full up elevator trim.



Full down elevator trim



Full left aileron trim



Full right aileron trim



Full left rudder trim



Full right rudder trim

My friends the sun is coming up over my North Carolina Beach town. I am in desperate need of coffee and will need to take a break. I appreciate how hard you are working on figuring this out. I will be back soon to check for further messages from you. Thank you. Chris

When on channel 63 without scanning. It goes back and forth between CRC invalid and valid CRC found it's strange. Do you understand what I mean. Here is what I see without scanning.

Invalid CRC



Valid CRC

I will be back soon to see if there is progress and how I can help. My brain hurts now. Haha

I'm looking forward to your creation. I must work today at 9 a.m. but will surely be in touch when I return home. Thank You. Merci beaucoup. Chris

You are correct I completely forgot to relay full throttle information. When I get home today I will gladly do that. Will you then incorporate it into the test build. Thank you for all of your effort. I admire the tech skills that you have. Chris
