RFCOMM on OPP always gets disconnected Reply-To: BlueZ development List-Id: BlueZ development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Sender: bluez-devel-bounces@lists.sourceforge.net Errors-To: bluez-devel-bounces@lists.sourceforge.net Hello, After getting a java OBEX implementation to work last week, it suddenly stopped working. Now, every time I try, the RFCOMM connection gets disconnected shortly. It seems that for some reason the target (n-gage cell phone) is disconnecting. My code is virtually untouched (I reverted back to a backup revision, but due to some mistake on my part I'm only 95% positive it is exactly the version which was working previoulsy). Just before it stopped working, my usb HUB fried (got lots of error on the bus). Now this bad device is out of the game, and no more errors have been reported in the system logs. Maybe it damaged my dongles, which were plugged in? Or maybe I'm missing something obvious? Here is a dump of a typical attempt. Does it look correct? uber ~ # hcidump -XV HCI sniffer - Bluetooth packet analyzer ver 1.31 device: hci0 snap_len: 1028 filter: 0xffffffff < HCI Command: Create Connection (0x01|0x0005) plen 13 bdaddr
