 Hello,
    I have several questions.
    First ,a bluetooth device was expected to act as GN with the command "pand  --listen --role GN".But the GN could be connected by only two PANUs.The third PANU cannot conect to the GN any more. Why? And how to set the maximal user numbers of a GN?
    Second ,I used some bluetooth devices to form a simple adhoc network based on BNEP protocol, which can be shown as the following figure:
     PANU1--->GN<---PANU2
    When GN was only conncted by PANU1,the data transmitting rate could reach about 50kbps.However ,when the GN is connected by both PANU1 and PANU2 ,the data rate reduced to about 8kbps.Why? What can I do to solve this problem?
    Thanks a lot!
                                                  													Cloudshang

sounds like a chip limitation. Add --master on the GN to force the role
switch.

The --master option should also help, because it will combine all three
devices into one piconet and thus the GN not longer have to follow more
than one hopping sequence.

Regards

Marcel
