Will bluetooth near MP cause a problem during flight?

[stressor]

I will to attach one or more small bluetooth device to the MP (eg location finder) I know it might cause interference. I would be flying with visual LOS. In reality has anyone tested whether bluetooth actually causes interference / irratic behaviour / poor feed / bad control? thanks

Bluetooth usually does not interfere with the Mavic. Maybe class 1 devices with high data throughput will do so, but that's not the case for such tags.
In any case be aware about the VERY limited range of such devices. A better solution may be a Loc8tor tag which I am using by myself.
