Hi,
I’m currently working with BlueZ 5.43 on Ubuntu 16.04.1 and I have two questions about the 1) pairing devices and 2) the DBus object paths of paired devices.
I do the normal process for adding pairing a new device: 1) discover it, 2) pair/bond with the device, 3) connect and 4) read.
The first issue I found is related with the pair/bond. For devices that I’m currently testing (weight scale A&D UC-352BLE and blood pressure monitor A&D UA-651BLE), I’m unable to use the BlueZ’s DBus Pair method, because it fails on the authentication. I can’t understand if it is an issue with the devices, or if it is some limitation (or configuration) of BlueZ. Could you please shed some light into this?
I also found out that when I try to connect with a not paired device, it successfully pairs/bonds with them - I do steps 1 and 3. After that, the device stays paired and I’m able to connect and read values from it. Attached follows two files with the logs taken from btmon, for the situations described above.
The second question comes in line with the first, as the device’s object paths are registered after the pair and connect. But I noticed that once I disconnect (may no be immediately), the services and characteristics' object paths disappear. One I connect, they are registered again - I presume it takes some time because the device is being inquired for its services. I could not understand if this is by design, or if something is wrong… I believe on the first option, but would like to know why it is designed as such. Is there any way to get the status of the object paths, i.e. are they registered? Also, how does the DBus Device’s ServicesResolved property relates to this?
King regards
Jorge Miranda
