Version of gattlib

[aliale09]

Dear Mr. DeanCording,
I am sorry, I couldn't find your email using git.
So I am writing this issue with a hope for your help with compiling of owonb32 client under Xubuntu 18.04.03. It's not possible to compile the client. As I could see from the gcc log, the problem is in wrong version of gattlib I have in the system. There is no specific information about the version you used.
Would you be so kind to specify it?
I have compiled the library to work with Bluez 5.49.

The client compilation errors are likes this:
owonb35.c:575:71: note: each undeclared identifier is reported only once for each function it appears in owonb35.c:575:22: error: too many arguments to function ‘gattlib_connect’
connection = gattlib_connect(NULL, address, BDADDR_LE_PUBLIC, BT_SEC_LOW, 0, 0);
^~~~~~~~~~~~~~~
In file included from owonb35.c:38:0:
/usr/local/include/gattlib.h:276:20: note: declared here
gatt_connection_t *gattlib_connect(const char *src, const char *dst, unsigned long options);

Thank you for contacting me about this. It appears that the GattLib library has been updated recently to support Bluez DBUS. I would suggest trying GattLib v0.2 release https://github.com/labapart/gattlib/releases/ tag/v0.2 Let me know how it works and if there is still a problem, I can look at over the next few days.

Hi Thanks for replying me. Unfortunately, there is another problem under my home Ubuntu 18.04. When I try to compile libgattool v0.2, it complains: No such file or directory #include <bluetooth/uuid.h> And there is no such file as "requirements.dep" in the latest gattlib-master folder: libbluetooth3 libbluetooth-dev libglib2.0-dev python3-dev libpython3-dev I suppose, libgattool v0.2 uses libbluetooth2, and I should install corresponding libbluetooth-dev. It might be a problem to go back to its previous version for the system. So I will try to compile everything at PC on my workplace, where Ubuntu 16.04 actually needs to become connected with the Owon 35 multimeter. With best regards and hopes, Alevanau, Aliaksandr

There are precompiled versions of Gatlib that you can install without needing to compile it. They are linked to on the Gatlib GitHub page.

Hi again, Dean

Thanks for your advice.
I did as you said, just installed latest gattlib with legacy Bluez support and downloaded binary owonb35 client.
It works, but periodically prints out together with readings:

Unrecognized packet: 1a f0 04 00 07 00 1a f0 04 00 07 00

Maybe it's because of a new version of these multimeters, I don't know.
However, multimeterBLE APP under Android works with it well.
Would you be so kind to tell me what is this about?
May this unrecognized packed appear because of Bluetooth adapter, or it is sent by the meter itself?
I have purchased it from:
