Do smart phones support "LE Long Range (Coded PHY, S=8)" Perplexity says it can transmit up to a 1km in ideal conditions. Otherwise it's 10-30m indoor.

First responders have awesome tools. But in tough situations, even common folks need to help.
After what happened in Myanmar, we need something like this that works properly.
It has only been tested in controlled environments. It can also be improved; I know BLE is not _that_ effective under rubble.
If you have any feedback or can contribute, don't hold back.
I don't know if phones support LE Long Range. I will look into it [1]. Thank you!!
