Bluetooth module shutdown

Hello,

I,ve purchased a bluetooth module together with my new board. In principle it's working fine, but I'm a little bit confused about the shutdown procedure. Is it ok to just drop the power?
Normally raspberry pi's need a graceful shutdown in order to not destroy the file system on sd card, but I couldn't find an option for that. So what's the correct procedure for the bluetooth module?

Regards, Ulrich

Hello Ulrich

Yes correct you can just pull the cable to turn off or plug to turn on. You are also right with the graceful shutdown but this is most important for DaVinci for example where you have lot of things and driver loaded where it's important to proper shutdown.

The BT module is running a very simplified  basic OS with very few things loaded just to make the bridge so we did check as we did not expecienced  any problems rather than putting an additional button which would have unnecessarly complicated the design or make some specific shutdown provedures we decided to go that way

Anyhow in the remote case the sd os gets corrupted for some reasons here the link to the image you can reburn and go again in no time.
