Need some help debugging code for Ultrasonic Tank Sensor
Hello everyone, my first post.
In github there is this code https://github.com/frewie/UltrasonicTankSensor.git - which allows for an ultrasonic tank sensor to be connected to the underside of a tank, the sensor sends a ping through the tank to the top of the fluid level and gives the time taken for the ping to return to the sensor thereby measuring height, from which volume can be calculated. This information is then sent to SignalK. The code is a little old - may have been written prior to SensESP v2.
I'm new to coding and can't get the code to compile, even when pegging all dependent library versions. (I'm looking to run this on a ESP-32 board.) I've also tried to uplift the code to SensESP 2 following the guidance on the SignalK site, but no luck. I've spent a number of days on this and I'm sure someone will be able to take a quick look and spot the issue right away!...
Subscription to server status
I'm developing a customised browser in QT6 for SignalK Server (if you are curious, this is the github: https://github.com/openfairwind/fairwindsk). How is possible to know if the server has been restarted? Basically, if an admin restart the Signal K Server, I should restart my browser as well to update, for example, the application list.
Help Posting Values to SK
I think I must have misunderstood something major so I hope everyone can correct me.
I am trying to update a value in SK. Here is a test value json string
{"updates": [{"values": [{"path": "electrical.batteries.123.capacity.timeRemaining", "value": 3455}]}]}
Dropped into the data fiddler it updates perfectly.
