Hi
I'm currently working on a research project where we are developing a
framework for ad hoc network based application on J2ME using Bluetooth
as a reference implementation in the network layer.
We currently have code running that connects to phones and allows them
to communicate. However we have problems connecting three phones in a
network.
So far we have found that device discovery can not be done in parallel
on the phones. Does this mean that we can not connect a phone to more
than a single device at a time?
We are currently using the RFCOMM protocal for communication, does this
force any added restrictions as to how many connections can be open at
once? The Bluetooth spec states that a Bluetooth piconet can consist of
up to 8 devices (one master and 7 slaves). Do mobile phones not
implement this or is it possibly just a limitation in JABWT?
We are currently using 3 phones for testing, SE p900, Nokia 6600 and
Siemens S65. All three phones have different behaviour as to how they
handle different events. And the SE p900 actually have an erroneous
JABWT implementation.
All answers are highly apreciated,
Regards
