Hi,

After a long time I took my OSTC 4 for dive(s).

1. While trying to setup cc / oc gases computer freezed few times - had to wait until it powered of automatically.

2. My first idea is to update darn thing but bluetooth does not stay on. When enabling bluetooht in settings the check mark disappears after few second. Bluetoot device is not visible in laptop (windows) or mobile (android).

Anything I could try?

rte 2.6 OS 1.5.6

-- Edit --
1. Tried hard reset (charging + magnet) -> no help
2. Tried reboot + right button --> boot loader --> bluetooth device not visible

Hi Riku,

is the voltage of the battery shown? If you have not used the OSTC for a long time it could be extrem low.

Kind regards,
Thorsten
