#Dynamic switching of binding phrase

Please correct me or, if possible, elaborate if my assumption is wrong:

  • assuming I can allow my system to be disconnected for a few seconds (the primary drone would fly with autopilot)
  • I could first switch the UID on my TX by updating the UID array (common.cpp:146) to one generated with a binding phrase for the proxy RX and then regenerate the FHSS table with FHSSrandomiseFHSSsequence(uidMacSeedGet()) and the communication would automatically jump
  • after the next sync packet, the proxy RX would automatically synchronize the HFSS index and the connectivity would be properly established

I was thinking about reading an AUX channel to determine which UID should be used in any particular case. Also, maybe if the AUX channel is also sent through the proxy, I could disable the proxy transmitter (as in the SX12xx) so that it doesn't use up power while hanging in the air doing nothing. Is there a simple way to either limit the output power to like 0.01mW or completely pause the TX to conserve energy, or do I have to use an external circuit to cut power to the proxy TX while the proxy RX is not receiving any data?

What are your thoughts about it? Am I far off, or is this more/less what needs to happen to have the ability to switch RXes mid-transmission?

Why switch binding phrase? Just power down one radio and power up the next

not military - rescue missions for dogs

#

and other animals

#

Especially in remote locations where those poor animals are abused. Spring is coming, there will be floods and I am just trying to come up with some way to proactively create ways to help.

#

It's the same every year in Poland. Hundreds of dogs and cats and other small animals die just because there is no way to pick them up and transport them. IDK if you have experienced things like that - I have. Back then, I could do nothing to help it. Now I can and I want to do it. I also have 2 dogs rescued from the side of the road that someone left to die in the middle of winter.

#

I don't really care about military if that is your problem.

#

They have enough money and stuff, they don't need me to do things for them.

#

As for your other question, please read what I wrote. It's a 2 RX setup in one place. A proxy as I call it.

#

@glad adder If, however you say that's final and you don't want to help that's fine. I'll do it myself but I will make sure to mention this once my drones will take part in the rescue. Qui pro quo.

#

@tawny jolt !military I get. I am not in a combat zone of any kind. I live far from any wars but very very close to spring. My hometown was already flooded a number of times. It happens almost every year.

#

https://www.netflix.com/title/81318108 check this out if you have doubts. Also in Germany last year and a year before that a number of people died from floods simply because there was no way to reach them, send them supplies like fresh water and food. Read the news - we don't need war to make use of drones that would save people. A small dog can be lifted by my hexa but not if there is no way to go as low as the roof of a house.

In 1997, scientists and local government officials in Wrocław face life-and-death decisions when a destructive flood wave threatens the city.

#

But like I said, ok - I'll do it myself, not looking for help. And I will not be quiet about how the community has responded to my question.

#

just so that you don't take that away later on...
