Look for an IC with those markings:
- nrf24l01+
- A7105
- CC2500
- CYRF6936
- XN297 or XN297LBW
- HS6200
- LT8900 / LT8910
but sometime one of those chips is built-in another one, that's when we need SDR to try to reverse engineer the protocol ...
Regarding hand soldering QFN28 ICs (I used solder paste in the end...), that was not easy, but worth it
Now I can print in the living room while watching TV with my wife and she won't complain of the noise anymore

Hi friends, I am new here and I have one ( or more ) question concerning protocol for Hubsan H107D.
When I bind it with my T8SG Plus, I can fly with, I can swith the LEDs, I can set the frequency, it all works ....
But it looks like the switching on/off the camera don´t work. I can recognise it on the RSSI value on the Hubsans monitor , only on this value, because there is no video on my screen and I am trying to find where the fault could be ....
Without drone ON the RSSI is about 35, with drone ON the RSSI is about 89 and changing through the T8SG the frequency shows changing the RSSI - when rare away from the frequency set on the Hubsans monitor the RSSI falls down, tune it back brings the RSSI on The 89-90 levell. But switching the camera ON/OFF brings no result.... Do you have any idea, why it is so?
Has anybody already find the solution for this " no video " issue? I found some interesting infos on one forum. They speaks about LDOs ( my are OK ) and XTALs 6.000 and 8.000 MHz ..... and also connecting the analog video to the Pin10 of vTX . I am collecting courage to do it, but perhaps more simple could be to connect the output for goggles to TV video input, what do you think about it? Or did it somebody already tried?
I know, this part belongs not exactly to this protocol development thread and I hope you will not kill me ....
No video issue..
