Hello everyone
I have a question concerning the Bluetooth module and that you can leave the moment during the operation plugged into the SYS port if the connection is disconnected via Bluetooth or you have to remove the modules for safe operation of the SYS port.

I recommend to unplug the module from the SYS port, or you can install switch that will enable power supply for BT module.
It is because of security reasons and interference with radio signal.

If you just remove the SYS connector, then Bluetooth stay active.
Interference with radio signal will stay....both working in 2,4GHz...is it not better just disconnect power?
Right, or i´m wrong?

Just to clarify:
Do you think it is safe to leave SYS port connected to BT, as long as power to BT is disconnected?

Manfred

It is better to turn off the power because of possible interference.

Sorry to ask again, but it is still not clear to me.

We have 3 connections of the BT
- logical in the software
- physical power of the BT
- physical signal to the SYS-Port

Question:
Do we need to disconnect all 3 connections to be save?

Is it sufficient to:
- disconnect logical in the software
- disconnect power of the BT
but leave plug in SYS-Port

It is sufficient disconect power of BT. The best is use some power switch.

Could someone please recommend a small power switch that would work for this? For tuning I want to avoid having to plug/unplug the unit every time I want to make a change.
