Scanner feature #13

Open dg8jt opened 1 year ago

dg8jt commented 1 year ago

Hi Roel, thanks for that great Software!!! I've just running 2 TBeams here 24/7. As the Frequencies are not standarized, the idea, is to implement a scanner function. Means for a stationary RX to have a switch at the web interface, where can set it on and put a list of freqencies to scan. If scanner mode is enbabled, the the RX looks 2/3 Min. at the freqency, if no vaild signal, then step to the next one and so forth. If a valid paylod is found, scanner stops until they lost the signal, wait a while appr. 10min, and scanner starts again...

I guess that helps a lot to catch the ballons:-)

What do you think?

Greetings Joachim

Hi Joachim,

Thanks for your suggestion!

That is a good idea and I've got already more requests for some kind of a scanner function. I will put this on the "todo" list and keep this issue open.

It might take a while to get this implemented :-)

And if you have more ideas for this new feature, just add to this Issue.

Best,

Roel.

Hi Roel,

thanks for comming back. I'm using a while the RDZSonde Programm for the TTGO's and that one has a nice scanner functionality. Have a look at - https://github.com/dl9rdz/rdz_ttgo_sonde - may you know it already or find some interesting ideas or code.

Hi Joachim,

Thanks for the tip! I've got that program now running as well. Big difference is however that the weather sondes transmit almost 100% of the time, so they are easy to catch. LoRa transmits only about 200ms per usually 30 seconds. So you need to listen longer and it is easier to miss a transmission.

Currently I'm thinking of adding some lines to the top of webinterface where you can add up to 5 (?) frequencies, LoRa mode and scan duration. That should not be too hard to implement.

Hi Roel, yes understood. regarding timeing, that is what i wrote in the first post. Scanner should stay for example 100 sec. on one frequency, that gives a chance by 30sek transmitting interval, to listen at 3 x TX intervals, then step to next one. (has to be tested) At least, when the RX has NO more a vaild signal, the it should wait for 5 Min. before start the scanner again, as sometimes, especially at startup and drop down the signal can be lost for a while... And yes, 5 Frequencies should be enough....

When i can halp for testing, plase let me know.
