I think the way the spec phrases it is that you must inquire for at least 10.24 seconds to have a good probability of picking up all devices. However, it doesn't say that the inquiry process will stop after 10.24 seconds. The host specifies how long it wants to inquire for in one of the parameters to HCI_Inquiry. If the host says to inquire for 30 seconds (or whatever) then the chip quite happily will. hcidump -X -V should reveal the parameters to the HCI_Inquiry command. >>From there you should be able to work out how long the chip has been told to inquire for. - Steven -- This message has been scanned for viruses by BlackSpider MailControl - www.blackspider.com ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
