Boat Instruments Display on m5stack tough

[mgrouch]

Gave it a try; it connected to OpenCPN a few times but was unstable.

Checked all the ports, which were correct. Tried burning it again and followed all of the directions at the github.

NMEA 0183 and SignalK connected a few times after a while but nothing reliable. Used 10.10.01.1.x while using the AP on the Pi.

Any ideas?

What do you mean it connected to OpenCPN?
There is no code in it to connect to OpenCPN. 
What and how did you test it?

If you have issues with NMEA 0183 and SignalK connections 
sounds like you having WiFi issues and not software 
issues. Did you set your WiFi country on your pi? (not
setting it caused poor wifi for me in the past).
Check your WiFi signal quality and antennas. 
It works reliably in my tests more than 50 feet away from Wifi router. 

Might be you mistake going to power saving sleep
after 30 mins of no touch activity with losing connection. 

How do you know it loses connection to SignalK or 
NMEA 0183? How are you checking it?
