With almost the same setup as previous test, with more time, my father help and phone communications to discuss about how it goes, I did some more tests.
Setup
- 2 ESP32 devkits, one plugged on a laptop usb, and the other one on a usb battery
- one setup as an AP, with code ligthing an LED when there is a connected client
- one setup as a client, with LED ligthing up when connected to the AP.
- code si simple arduino framework based stuff, and there is no control of the mode the wifi is set at.
Testing
As last test, we used one fixed device, and the other one moving. But this time we went to an extremity of the street for the fixed one, to get us more room for testing.
I went up to about 200m before the two devices lost signal, I managed to reconnect and then go further, and lost the signal again at about 240m. That time it didn’t reconnect. Tring again and again to reconnect while coming back, even at the 200m mark where it previously worked, there was no way to get the signal back until I was at around 180m from the other device.
It is worth noting that this was in direct line of sight, but on busy and touristic place, near the Versailles Castle, which means a lot of phones were likely around and can add noise and make the range fluctuate quite a bit.
Conclusion
I guess with playing with the modes and speed we can hope to go a little further. tho, 180m should be sufficient for a 100 cones with 6 feet spacing, but not for 7 feet.
