PowerShell and Ping to find the ESP8266
The ESP8266 has it's own WiFi, but it should be on the local P9 Member WiFi as well. The IP address will be different at each session. How can we find it?
First find your PCs IP address. On Windows, from a command window type: ipconfig (and press enter).
Note the first 3 parts of the IP address, e.g. 10.240.3
Copy this piece of code into a PowerShell window, edit the IP address at the start with the 3 numbers from your IP address, then press enter.
$iproot="192.168.1"; $ipmin=1; $ipmax=254; foreach ($i in $ipmin..$ipmax) {ping -w 50 -n 1 "$iproot.$i" | find 'Reply '; Write-Progresctivity "Progress ..." -status "Checking: $iproot.$i" -percentComplete (($i-$ipmin)/[Math]::max(1,$ipmax-$ipmin)*100)}
It should show you the IP addresses of all the computers. You could put each IP address into your browser to see if it's the ESP8266. The ESP8266 uses TTL=255. This reduces the number of possibilities.
