Cannot change settings on OSTC Plus with Subsurface, this used to work

Post by jb2cool » Monday 13. July 2020, 18:31

I use Subsurface to download dives from my OSTC Plus as well as to adjust the settings like the custom text and sync time, this used to work just fine but when i tried it today it fails, i think this change is functionality came with a firmware update (I think this was ok with 3.07 firmware). I've tried downloading previous versions of Subsurface to see if that was the issue but the last few releases all have this same functionality.

Output from the log when i tried this is here:

Subsurface: v4.9.6, built with libdivecomputer v0.7.0-devel-Subsurface-NG (48e46cf7775452740f67ba72d9c5a0960ebf3718)

I can read the dive computer settings just fine but i can't write new settings. Do you know what this might be? If there have been some changes to Bluetooth in the firmware and there needs to be a corresponding change is Subsurface/libdivecomputer then that's probably doable but would need to know what needs changing.
