Hi,

Sorry for the newbie question.  I stumbled upon a TI sensortag and was able
to communicate with it using the gatttool.  Now I am trying to figure out
how to build an app around that.  Googling has shown me lots of examples of
folks using expect scripts (around the gatttool).

I was hoping for something in C or python.  Is there an example
program/script around that I can copy and expand to get me started?

Thanks!

Cheers,
Don

bluetoothctl has some generic support for GATT attributes, in addition
we have some examples in python under test/example-gatt-client and
test/example-gatt-server.

Hi Luiz,

Hmm, the example program complains about no such interface 'org.bluez.GattService1'.

Originally I thought that was a generic bluez interface but now I am
wondering if that was specific to the example program.

Any tip on what the expected interface should be (so I know what to add)?

(by the way, I am using bluez-5.36 if that helps)

You will need to pass -E to bluetoothd to enable the experimental
intefaces, btw there is a recent change to GATT server/peripheral so I
suggest you try with the current version on git.
