Made a simple galaxy watch app for data monitoring

I made a simple Samsung galaxy watch app so that I can monitor some data live while I foil around the lake. I was previously using Alcor Telemetry from the app store, but it stopped working. It was also removed from the app store as far as I can tell. Right now, my app is only monitoring speed, Voltage, current in, and mosfet temperature. I determine speed using location data in mph. The app allows you to adjust the cell count, and it uses this to show average per cell voltage.

I should be able to share the apk with people if anyone is interested. I have not tried to compile it yet though. I will look into this if it gains traction. I know others have made apple watch apps so I figured I would put something out there for the rest of us.

For reference I only have a galaxy watch 4, but I believe with the API I used, it should run on anything else newer than that as well.

Nice work!
Just to be clear, this is for connecting to a vesc with Bluetooth?

That is correct. Connection and polling over bluetooth. Polling is set to happen every 2 seconds.

I was looking for something similar. I am using my s7 but it is not very handy. Some data on watch would be really nice. You use the gps of the watch fir the speed?

Yup. I had a chance to test it out today on the lake. It connects and data updates as expected. I think I am going to increase the frequency the speed updates since it felt too slow when I was using it. Also, the current isnt updating as it should. Just reading 0.00 the whole time.

I should be able to fix that too.

Exactly what I was looking for: Could you share the apk?

I put the apk here.

I updated the speed to update every 0.5 seconds. I will leave the file there for now. I am going to work on it more soon. For some reason, the current in is still not working.

Let me know if the link isn’t working or you have problems with the app.

For your information.
It works on an Android Pixel7 phone too.
Can you maybe add an option to set it to km/h?

That is pretty cool. I really didn’t even think about trying it on a phone.

I can look into it. Maybe I can add a settings screen swiping right to left, or just put another button to switch from the imperial system to metric below the cell count adjustment.
