Aside from my poor programming skills I come across some other issues - but maybe this input will be enough to guide me to my goals!
* the unit will 'start-up' after connecting to the Wi-Fi network - and a verification from the app that it is actually connected with a capable device. This "handshake" needs to be implemented in the programming. (can it be done in any code?)
On GitHub I found the following regarding the handshake procedure; https://github.com/Paulie-P/SonarInterface/blob/master/init.py
* listeningport = 5000
* Server? In the output code I also found on GitHub the log shows Server "T-Box". Not sure if this of any need. https://github.com/scherererer/SonarPhony/issues/1
* Don't know for sure if IP addresses are that important. I remember the original module had an IP of 192.168.1.60 and gave my phone the IP of 192.168.1.100/101 if I'm correct.
