Hi, We want to use Class I dongle to increase the range of the content we want to push within our Bluetooth Zone. For this we have ordered some of Bluetooth Dongles. All the suppliers have claimed that they are Class I dongles. But to our surprise, when we tested it we figured out that only one type out of three types is having good range. The other dongles does not have good range. They are all having CSR chipset and shows me same set of firmware.I am using Bluez 4.26. I surfed on net and find out that the 'Transmit Power' is the value that I should look for. When I did "#hciconfig hci0 inqtpl" it gave me IO error! With "bccmd" I found out that one of the dongle which does not have good range has 0x0004 value on address 0x0017 and the one which has good range has 0x000f value on the address 0x0017. Can someone please help me how can I check what values should belong to Class I and Class II dongles? Also is there a way to change these values using "bccmd". I have already tried "#bccmd psset" but it did not set the values correctly. Your help is much appreciated, I am totally new to Bluetooth subject on Linux.
