Moderately well. I can get a couple miles of range punching through trees, far far better than any other unlicensed option. Chirp spread spectrum is pretty cool

- polishdude20 6y agoThat's cool! Might try it out
- abstract_put 6y agoCan you elaborate on specifically what you have that's getting a couple miles? I tried out Meshtastic with a bog standard board exactly as it existed. I carried it down the road and found it got ~500m of reliable range with no obstructions. Has the software improved significantly, or is there different hardware to support getting multiple miles?
- adrianpike 6y agoBoards are the Heltec boards that are an ESP32/SX127x. One of the boards is using the stock antenna that came with it, the other has a TBS Immortal T I had lying around. Using the 915mhz bands as well. I use it out in the mountains, with line of sight between hilltops, but pretty forested so it's having to punch through foliage. I did some unscientific testing around my house and did notice a lot less range, I'm suspecting there's a fair amount of noise from other things in the ISM bands in the city.
