First of all, hcidump produce better output when you use -X and -V switches. :-) Well, this mode change event is turning the connection to sniff mode, probably to save some power. And according to your dump the command to change the connection mode was sent by your headset. Looking closer we can see that the interval between two sniff anchor points is 4096 baseband slots that give us 2.56 seconds! This really seems to be overkill and it's probably causing the delay you're experiencing. I don't think there's something you can do to avoid this. btsco could change the link policy settings to remove sniff mode, but this would require root privileges and I really don't think btsco shoud do that. Marcel, am I right or is there anything that might be done and I don't know? Best regards, -- Ulisses Using Tomcat but need to do more? Need to support web services, security?
