Tried to connect with bluez:
$ sudo bluez-simple-agent hci0 DC:7A:F8:10:AF:A5
Creating device failed: org.bluez.Error.ConnectionAttemptFailed: Page Timeout
Stupid question, how do I read the firmware version? Sorry to ask
silly questions but this my first attempt to use this kind of "AT
commands" via GATT
Here is the dump:
