Consider new hotspot channel selection #203
Comments
Are we not able to let the Pi chose the best channel at the time? At a competition event, whatever the default channel is is probably going to get pretty crowded. |
That sounds like a separate thing to me and also is a much larger and complex task to implement scanning and channel selection. There's a thing in the kernel for ACS, but we'd need to test it with the Pi WiFi driver and things. |
Ah I see, I had thought it was as simple as |
It is sometimes. We need to make sure that both the kernel and hostapd are being compiled with Unfortunately hostapd silently fails if any of the above isn't true, so I'd rather we were really sure. The fallback mechanism appears to be a random channel. |
The other approach would be to manually do a network scan before starting the hotspot to find an uncongested channel. However that would delay the start of the hotspot. |
We currently hardcode the WiFi channel for the hotspot. We should make this an option in Astoria.toml so that we can change it without changing code.
