Hello, I have found out that the Asus BT-400 is not working very well on linux. http://marc.info/?l=linux-bluetooth&m=140732083213294&w=2 this was for the older bluetooth 2 protocol "rfcomm" Then I used the BT-400 stick for tests with the sensortag: http://mike.saunby.net/2013/04/raspberry-pi-and-ti-cc2541-sensortag.html here it turned out that the stick does not work too. (lescan aborts, always disconnects, cannot read sensor info) Then I bough a belkin stick, which has the BCM20702A0 too. Same result: unusable, like BT-400 So, I would say the BCM20702A0 is not very well supported on linux? Anyone have success with this chip? A Stick which seem to work: I bought a sitecom stick, which announce itsself in dmesg as: CSR8510 A10 this does work with the sensortag! regards, Martin -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
