(Can you write the transponder link you have posted? i did not find one yet).There is nothing to configure, the code to be entered on your declaration form will be given when purchasing the transponder.
The advantage of purchasing is that there is only one code and the device can be put on any device of the same weight class.
The code for DJI for its devices is 1581Exxxxxxxxxx, the x's are the drone's serial number.
You can consult the documents on the Internet, look for European drone laws, if I remember correctly almost 600 pages.
Unrinkable documents to read!
There was a draft decree with technical specifications for a reporting device.
This is not compatible with an ADS-B neither in the frequencies used, nor in the protocol.
It is in wifi in 802.11n at 2.4 GHz, in Ad-Hoc single frame mode, unencrypted, every 3 s and every 30 m.
For wifi reporting, yes, it is possible. But different brands use different software. It's probably easy to see if there's a drone in the air, it's just triangulation. But to read the details, you need specific brand software.
In fact wifi is just a (set of) communication protocol. It does not prejudge the CONTENT. And precisely, it is this content as well as the presentation of this content that is defined by DJI and the others with their applications in question. But if the device is capable of generating WiFi frames, then the rest is a matter of programming, therefore firmware. The formatting (presentation) of the data will be carried out by an application, we can bet that it will be on smartphone or tablet (the range of the wifi being limited).
Regarding the determination of the position, it is not planned to do it by triangulation but the device must transmit the following elements:
starting point latitude
longitude of starting point
Plus a "manufacturer" identifier, it is a trigram for example "DJI" plus a unique number provided by this manufacturer.
If it is an independent transmitter added to the device, an identification code will be given with the transmitter that you will have to put on your identification and registration form as a drone pilot.
Personally, I am waiting for the beginning of next year to know if the code will be valid in all states or if each country will have its own.
Everthing you say is just correct, but ( it is my thought) article 22 from regulation 2019/947 says that UAS which do not comply with requirements of part 1 to 5 ( C0 to C4 transponder included), shall be allowed, for a transitional period of two years, to fly in A1 if less, than 500grams following uas.open.020 (1) . (just that part 1 of uas.open.020), in A2 if less, than 2kg followinf uas.open.030(2) ... and so on..... The "transponder will be in force only after this transitional period (2023 or 2022) for UAS made without CE marking Class.What do you think?
P. S. i cannot believe, yuneec made a " brand" new drone ,the h520e, without CE class Mark. i know it is a drone made for working but it will be so, much easier to work in open category than in specific category.
