Hi Steve; I've put the ESP32 back to 192...1.34 connecting via WiFi
the other solar logger is now at 192.168.1.42 also connecting via WiFi
I looked at your sketch, and considered running it - but couldnt find ping.h
thought about making a MUCH REDUCED sketch just to ping that one address; however
Testing from my laptop makes things simpler - it eliminates the network monitor as a source of these problems.
With the laptop connected with ethernet - (IP 192.168.1.26) I can ping both units.
With the laptop connected with WiFi - (IP 192.168.1.68) I can ping .42 but NOT .34.
@wildbill - I have wireshark up and captured some pings but dont know how to make sense of results?
pings to solarlogger 192.168.1.34 (fail) & SolarLoggerTest (now at) 192.168.1.42
