Hi there.

Alex asked me to share my personal finding about R01’s antenna.
According to assembly instructions antena should be mounted like so.

In this place signal reception wasn’t good, if any. Where my other devices reported 3/5 signal strength, uC’s nmtui didn’t even seen SSID being broadcasted.

improved reception to the point where i am able to use wireless connectivity to manage µC and vice versa.

I’ll admit that speeds aren’t particulary “fast”, testing from the same physical spot and on same 2.4G network with my lowend Android phone yields

while µConsole struggles to pass 10Mbps
