This happens consistently using hcitool as well, after 54 seconds a link created with hcitool cc is dropped. I've read over the FAQ and howtos on bluez.org and none of them appear to address this. Are there any low-level protocol docs which would suggest some sort of keep-alive which might be necessary? or is this likely to be a problem with my phone?
