Station mode instability - bcn_timout,ap_probe_send_start
I have a simple station mode app, and a laptop pinging the ESP31. I frequently see the ESP31 failing to maintain AP connection, with logs like this: dhcp client start... ip:192.168.1.103,mask:255.255.255.0,gw:192.168.1.1 <some time later> bcn_timout,ap_probe_send_start <a short time later> ap_probe_...
