New Hubsan Upgraded Version on the way

For telemetry hubsan should be in rx mode.I'm curious how they squeezed the telemetry packets in.Every packet frame is sent every 10ms.
On frsky you have every 3 tx frames one rx frame for telemetry..all frames sent every 9ms.

I had a look on the pcb .the setup is different than the normal Rf module we know ,there are 2 pcb antenna one for tx mode after the PA and one for RX mode? just before..

Not sure what you mean by "Hubsan should be in RX mode" but the X4 quad was turned on when I captured the data. And the bind was successful.

Anyways, I did a longer capture. Shot video at the same time. Will link to that once it's uploaded.

Until then, summary of what I did:

Start video record and LA capture at the same time.
Turn on TX.
Plug in X4 lipo.
Press trim button down to turn off lights. Then press again to turn back on.
Press right stick in to switch to expert mode. Then switch back to normal.

Then I went into the Main Menu.
Then started to switch the frequency. It was at 5740Mhz. Proceeded to switch to the next frequency every ~2secs.

5735Mhz
5745Mhz
5750Mhz
5755Mhz
5760Mhz
5765Mhz
5770Mhz
5775Mhz
5780Mhz

LA capture completed 1B capture. So I switched off TX.

Hopefully you can see a pattern.

If not, I can repeat and go through all the frequencies with a longer capture window.

Additional info: Telemetry data should be enabled because I can see lipo voltage on the TX LCD.

Video: Sorry about the low quality. Was messing with the software to keep the bitrate low...but I didn't think it was going to be THIS low. Upside, the video file was quick to upload to YouTube.

I think there is no telemetry.Maybe that voltage is from 5.8GHZ Rx module power supply.The tx was on,.... in 157 frames you should see the telemetry packets.

So they are sending telemetry and video with the 5.8 link?

Because they are not using a osd on the 5.8 ghz video.
The osd is added on the lcd by the tx. It doesn't show when recording with the tx. Or when using your own reciever.

And the voltage displayed is the quad battery voltage.

If spi you should see at least the RX strobe commands when going in rx mode
_spi_strobe(0xC0);0xC0
plus the timing every frame is sent every 10ms if there is no delay in between sent frames there is no telemetry.
Anyway it was too good to be true..

I think that voltage in the screen is tx internal voltage maybe from 5.8Ghz rx module...feed into mcu for monitoring.

You said you use some program to "arrange" data.Which program you use?

That F0 at the end of rx frame maybe is the rx pointer reset strobe command 0xf0.

I know for certain that the voltage displayed on the screen is the X4 lipo. Because you will see it go down. At 3.7v, you give throttle and it'll pull it down to 3.3v. Then come back up when you let go of the throttle.

Insert a new lipo. And it will show 4.19v again.

Yes Daryoon .it is clear now.There is telemetry every 4 tx packet frame there is one telemetry frame.I'm/was curious how they insert telemetry packets.

Oho,
thank you!Now is easier.
I couldn't do it myself here.I'm at work on company computer no administrative right cannot install programs.
Now is better.I can have a look.
