Error on EP500 #6

Closed nightmare-rg closed 2 years ago

Hello,

I tried bluetti-logger for EP500 but got this error:

➜ bluetti-logger --scan

I checked also bluetooth connection from iPhone and Bluetti App via Packetlogger and your results from https://diysolarforum.com/threads/monitoring-bluetti-systems.37870/ are the same for EP500. I am only wondering about the address. Not a typical mac address, but my magic mouse and other bl devices are also shown with this type of address. I tried it also with the mac from the Packetlogger but no Connection. I'm working on MacBook Pro M1 with PyCharm and use buildin BL. Any idea what's wrong and this error happened?

@nightmare-rg There's probably some slight difference between Bluetooth on macOS and Linux (where I've done most of my testing). I have access to a mac that I can use to test, and that error message gives me a pretty good idea of what's going wrong. Once I have some time I should be able to fix this and put up a new build.

This would be great. I want to use my Mac Mini M1 Server to collect stats from my EP500. Here are some additional information:

@nightmare-rg This will be fixed in the next version released some time later today (I still have some work I want to do).
