This looked like the perfect board for an upcoming project. Right price, right pinouts, I just need to flash ESPHome to it. The problem is I can’t get a reliable connection to WiFi.
There is one workaround that might help, reducing txpower in your yaml to ~8.5-10 dB (the antennas are bad and badly matched (SWR)). Doing this might completely ‘fix’ the situation (although you obviously won’t win any range competitions) for you in practical terms - or it might not.
