WLToys Q282G micro hexa 5.8G FPV

Can someone help to develop this protocol? I captured SPI data as below,

It's XN297 base RF chip.

I think this protocol is the same also for the second revision of the V686G and probably for some recent JJRC models as well

Hope this protocol could be deviated soon!

Any chance to develop this protocol?

The CSV files can't be used because the MISO and ENABLE lines are swapped in the spi decoder. If you don't mind fixing that I will take a look (don't have time to re-export them).

Looks maybe similar to CX10 but has 21 byte packet length.

What a good news is it !!

I swapped MISO and ENABLE, please check it out !

Thank you very very much.

It's very close to CX10. Will try to make it an option on that protocol.

The video capture is strange - two bits are changing in byte 14. Was more than one button push involved? Here's the sequence - how does the timing match what was happening during the capture?

I added a test build for devo 7e and 10. It's a protocol option to CX10. No video or pic support until we get more info on that capture. Channel 5 is light control when Q282 option is selected.

This test build works great!
Need to set reversed on AIL & RUD , light control (ch5) works fine, different FixID test OK ,I don't have time to do more test today,sorry!

Regarding video function , I captured SPI again, please check it .

Thanks!

Edit : Video function is triggered by one pressed left top button.

Forgot to mention that this version uses a hardcoded txid and rf channels for the Q282 to match your capture. The rf channel algorithm is not the same as CX10, so we need some captures from other stock transmitters for the Q282.

The new video capture shows the same pattern. It's something like bit0 means on/off, and bit5 means "switch to what bit0 says". I'll try to implement something for that.

I verified the test build still works with my Blue-A CX10, but setting the Green or DM007 options causes issues. Need to find what I broke.

Test builds are updated. Video support added (pictures should work too). As with some other protocols, you'll need to set channel 8 > 0, then back to < 0 to start recording. Then same again to stop recording. Putting the control on a momentary trim switch works well.

Aileron and rudder are reversed from what they were.

Hoping the bug is fixed too, but can't test at the moment.

Bug is fixed. Blue-A still works. Any volunteers to test Green and DM007 options?

Hi Hexfet,

The Second test build 7cb832a works perfect, All functions work fine!
It makes Q282G easier to fly , thanks a lot!

But I can't find MJX / Bayang protocols in this build, would it be possible to build a "SUPER COMBO BUILD"?

I added the updated CX10 protocol to the protocol_combo test build. You're welcome

Thanks !!
I'll give it a try later today!

I can test Green option in a few hours.
BTW, Good job Hexfet!

Thanks with new v686g works well. But i dont found X and Y calibration.

Tested Green option. No problem at all, working right

Thanks for testing
