[Bluez-users] general rfcomm questions

[Marco Trudel]

Hello

i now tried and read quite a few things about rfcomm and multiple 
connections... but still don't really know what i was searching for...
maybee someone here can help me (hopefully).

i have one device that needs to parallely serve a service to multiple 
clients via rfcomm.
- is it possible that the service runns on multiple rfcommchannels, one 
for each clients? what's the limit?
- or is the solution to wait for connections, and on a incoming 
connection close it to connect to that device (having the local service 
waiting for new connections)...
- does a inquiry block the whole device? i noticed that if a connection 
between my device and a client is etablished, i'm unable to run "hcitool 
scan"...

i'd really appreciate if someone had the time to share it's knowledge...

kind regards
Marco Trudel

you don't need different RFCOMM channels if the underlaying ACL/L2CAP
connection is not the same.

Don't understand what this is trying to do.

This depends on the firmware version. See other discussion in the
mailing list archive.
