I've got a couple of BT devices that transmit a relatively small amount
of data, about 300 - 500 bytes per second, depending on the device.
I don't buffer this data in any way, and go straight to processing it.
Periodically, with no apparent rhyme or reason, I appear to get a
re-transmission of previous data. In other words, my rfcommEventListener all
of a sudden gets called with a bunch of the same data that it was already
called with.
I can't figure out why this would happen. I can't imagine that it's
anything I'm doing, since, as I said, I'm not buffering the data, and even
if I was, I'm never manually calling that event listener anyway.
I tried, as a workaround to minimize the negative impact, freeing or
zeroing out the data in the IOBluetoothRFCOMMChannelEvent, but the the
system tells me that isn't my memory to go tampering with.
Is there something I'm missing? Is there some way that I'm supposed to
dispose of the data after I process it?
...Thanx...
