Hello Michael
thank you a lot for this information.
Another question regarding this topic:
Does it help/make any difference if the two dongles have a distance of
~11cm? Does this lead to equivalent/less interferences?
I have no idea about how radios send out their signals. I could imagine
that if they spread their signal and there's another dongle just above the
sending one that sends out a signal too, the interference is much worse
than if they have a little distance, because the point of the problem is
not right at the source.
Will rfcomm ensure the correctness of received data? something like a
checksum and automatic retransmission of data if a brocken packet is
recognized?
regards
Marco Trudel
