[Bluez-users] Connection lost transmisting large packets

Hello,

I'm building an environment where there's an workstation running RedHat
8.0 (2.4.21-mh2) (PANUwks)and all bluez packets downloaded from bluez
source-force website.. Another machine at the other side of bluetooth
link runs Redhat 8.0 (2.4.20-18.8) - (NAPwks)...

Ericsson Application kit is the hardware used, where PANUwks is a
point-to-point adater and on NAPwks it's a mutlipoint adapter... I'm
using bnep as encapsulation protocol on this communication, looking for
compatibility between an wired and wireless net and DH5 as packet type to
increase wireless network's throughput.

All latest versions of bluez packets were downloaded from bluez
source-force website...

Following are the doubts that I cannot find properly answers:

1-) What does aclmtu on hciconfig mean and Can I change this value? at
PANUwks, aclmtu is set to 672:10 and on NAPwks, it's 672:8. Is there any
issue regarding the differnce on field "packets" on aclmtu
(ACLMTU=<mtu:packets>??

2-) Transmitting large amount of packets at (an FTP), sometimes,
bluetooth connection is lost and I've got to restart hardware devices to
get them working back.. Looking into hcilog.txt (file uploaded on this
mail), it seems that packets are being retransmitted on bluetooth link
(packets with length of 672 bytes) on one direction .... Is there any
tool to troubleshoot what is causing this disconnection... HCIdump just
shows that packets stopped to be transmitted...By the way, what does
symbols "<" and ">" mean on hcidump ?? which one means "input" and which
means "output"??

3-) "Theorical Question": Do bluetooth connections work on "Full-duplex"
mode?? I mean, can I, for example, start an FTP from PANUwks to NAPwks
and, at the same time, another ftp from NAPwks to PANUwks?? doing this
connection is lost very soon.... on unidirectional ftp (i.e., from NAPwks
to PANUwks only), I get good tranmission, reaching 500kbps.

At this moment, those are some questions...

thanks very much,

Rafael Soares
