Hello everybody,
I am trying to compile thermometer example in BlueZ, but getting some
errors. Firstly, I configured and installed the bluez as explained in
readme file. I used some configuration parameters like --enable-health
--enable-thermometer. It gave me .o files for thermometer example, but
no executable file.
When I tried to link these .o files myself, I got these errors:
/usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5.2/../../../crt1.o: In
function `_start':
(.text+0x18): undefined reference to `main'
manager.o: In function `thermometer_manager_init':
manager.c:(.text+0x7c): undefined reference to `btd_register_device_driver'
manager.c:(.text+0x8b): undefined reference to `dbus_connection_ref'
manager.o: In function `thermometer_manager_exit':
manager.c:(.text+0xbc): undefined reference to
`btd_unregister_device_driver'
manager.c:(.text+0xca): undefined reference to `dbus_connection_unref'
collect2: ld returned 1 exit status
Could you please help me to compile and run the thermometer example?
Best regards,
Alisan

That code is just a plugin to manage thermometers. Health Thermometer
Profiles is placed on top of GATT so you will need neither HDP nor
MCAP. Onn the contrary, if your device is only using HDP this plugin
is unusefull for you.

Of course, I don't have any problem to share my repo. I'll move it to
a public repo in next days if you are still interested.

I insist again, HTP profile is not related with HDP :-)
When you pair your HDP device, the bluetooth daemon will load a proper
driver to manage that device using the HDP D-Bus interface, you can
see more info about HDP interface under doc folder. This interface
enables you to create/destroy health channels and send 11073-20601
APDUs.

Hello Santi,
Thanks for your quick response. Actually, we want to develope a health
device application that gets measurements from a Continua-Certified
blood pressure device using HDP.
I thought, it could be very helpful to look at that thermometer example,
am I wrong?
Also, if you share patches with us, we want to help you by testing and
developing the measurement plugins.
By the way, after executing bluetoothd, there were not any thermometer
HDP service in the running bluetooth services list. Does the problem
occur due to the codes or wrong installation?
Best Regards

I'm not sure what are you trying to do. Health and thermometer are
built in plugin, that means that the bluetooth daemon will load it at
starting time and it will load/unload the proper drivers to manage
such devices.
By the way, health plugin it's only required if you want to enable
Health Device Profile (HTP) and Multichannel Adaptation Protocol
(MCAP). They are helpfull if you want to develop applications over
11073-20601 specification. You don't need enable this if you are only
interested in thermometer capabilities.
Anyway, HTP plugin is still under development, I've a lot of patches
to upload yet so there is not much to do with it. If you are
interested I could set my current git repository wich implements most
of the thermeter functionality to any public site so that you can test
it and help me in development by reporting errors, etc. Any feedback
from your side will be very appreciated.
Regards.
Santi.
