Written and tested only on a Jumper T-Pro V2 with internal ELRS 1000mW module (oled LCD)
With the RSSI Model Locator.lua file Add also the two audio files. Eventually replace telemko.wav with the one in your own language.
Now uses language from SYSTEM folder and auto detect user language.
The beep is generated rather than being a file, so other files other than the lua file are no longer needed.
It also has haptic feedback and a large bar graph showing the signal strenght.
This code is derived from https://github.com/EdgeTX/edgetx-sdcard/blob/3f79e21fbfe480fa59393e3cc196e329d7bb185c/sdcard/c480x272/SCRIPTS/TOOLS/Model%20Locator%20(by%20RSSI).lua#L19 - Model Locator (by RSSI).lua by Offer Shmuely, and as I found it in my newly bought Jumper T-Pro V2 SD card and it was not working (it is designed for colour display ecc..) and I tought it might be useful, I decided to make this version for my radio.
-- There are two way to use it -- 1. The simple way: -- walk toward the quad/plane that crashed, -- as you get closer to your model the beeps will become more frequent with higher pitch (and a visual bar graph as well) -- until you get close enough to find it visually
-- 2. the more accurate way: -- turn the antenna straight away (i.e. to point from you, straight away) -- try to find the weakest signal! (not the highest), i.e. the lowest RSSI you can find, this is the direction to the model. -- now walk to the side (not toward the model), find again the weakest signal, this is also the direction to your model -- triangulate the two lines, and it will be :-)
