As far as I know there is no other compatible drone out there. But since the receiver inside the Typhoon H is an ordinary SBUS style (maybe PPM or something else) which can be unplugged and swapped into another drone it should be possible. For example it should not be too hard to install the Typhoon H receiver inside a DJI Phantom V1 or V2 since they are completely modular. You simply need to adjust the flight controller so it will work with the receiver as well as the remote.
I did not new about another protocol. I have only seen several people doing it. Seems like there are already PPM/SBUS converters available as well as the pixhawk able of understanding the Yuneec protocol. So it is not compatible with a DJI Naza right away.This is all incorrect information. The receiver in the TH has a serial output that is completely different than SBUS or any off the shelf RC receiver protocol. In order to use the TH receiver you will have to either program a microcontroller to convert the yuneec serial protocol to a known receiver format (like SBUS), or program the flight controller to do that directly. I know the PX4 flight controller firmware has code for talking to the yuneec receiver, but that is the only one that I'm aware of and I don't have that type of flight controller so I don't know if it is actually implemented.
The free connector on SR24 is with limited PWM output and the transceiver itself looks to have some compatibility with the Spectrum transmiters.
See GB203 manual for some details. All the rest should be discovered ib an experimental order.
I mean, you can use this receiver with a spectrum transmitter from Chroma.
I'll try to find the picture of the connection, but probably tomorrow. Now I'm pressured by time.

The Spectrum receiver at Blade 350QX can be replaced by a SR24. The Blade can be controlled then by ST10. I don't believe that this was planned in 350QX firmware but it works by accident.
The additional port on SR24 is connected to 2 in/out pins on the ZigBee SOC: P1_7 (pin37) and P1_6 (pin38) at CC2530. What the pins are doing depends on the SR24 firmware. I'm surpised that it was used for gimbal in the past.
However, the connector is not for programming. Programming can be done using testpads.

Ya it a no then lol!! Appreciate ur information someone will find it useful. Have a good evening!I did not new about another protocol. I have only seen several people doing it.

The Spectrum receiver at Blade 350QX can be replaced by a SR24 at the same port. The Blade can be controlled then by ST10. I don't believe that this was planned in 350QX firmware but it works by accident.

Yes, I could connect to the CC2530 and it answered with correct ID code a524 but when I read the FW I got an empty fileThe content is locked.

It's only capable of binding with the SR24 receiver. However, as Dylanfm and Helsner stated, the protocol specification is available and it is rather easy to write a Yuneec to PPM/PWM/SBUS converter with a Teensy or Arduino. The codes are somewhere here... and I may have something too if you need (Arduino/Teensy to PPM source code, partial telemetry implementation/protocol specification... ;-))Is st16 only capable of binding to yuneec products? Or is it possible to bind with other drones?
Would it be easier to capture the serial data using your PC between the flight controller and the SR24? That's how I was studying the protocol for developing telemetry for the Thunderbird firmware.. ;-)I really thought I had seen a SR24_rx.bin firmware file somewhere, but all I can find is the tx.bin file. Since I can't find a separate .bin file for the receiver but I'm pretty sure it does get updated, I think that maybe the flight controller firmware also updates the receiver SR24. So the only idea I have left to program my zigbee module is to write a serial boot loader to my zigbee module and then plug it into the receiver connector on my TH and try to update the TH's firmware see what happens.
