I am using a beaglebone black to try and connect to the CC2650 sensortag and just read temperature. I have the newest version of Bluez and Debian on the beaglebone and using the most current revision of the sensortag FW.
we know that we have to use gatttool to tell the sensortag I am interested in recieving the temperature (handle 0x24), however, when I try to send a command I get an error from gatttool saying: "A valid handle is required." I followed all the steps in the comments on the blog post to try and resolve this issue but it did not work. The interesting thing is I can read from handle 0x21 where the IR temperature data is stored, but since the sensor is not on the data received is 00 00 00 00.
Has anyone else encountered this kind of an issue using gatttool?
