EXACT STEPS LEADING TO PROBLEM:
(Explain in detail what you do (e.g. tap on OK) and what you see (e.g. message
Connection Failed appears))
1. Plug BT dongle #1 into PC
2. Establish connection to PC using BT dongle #1
3. Disconnect connection
4. Remove dongle #1 from PC
5. Plug BT dongle #2 into PC
6. Establish connection to PC using BT dongle #2
7. Close and reopen BlueMaemo
8. Remove dongle #2 from PC
9. Plug back BT dongle #1 into PC
10. Press "Reconnect"
Note: BT dongle #1 and #2 addresses are unique (different). BT device NAME as
transmitted by the PC is the same (since it represents the PC not the dongle).
List of paired devices contains 2 entries (for both dongle #1 and dongle #2)
Since entries in the list of paired devices are the names of the respective BT
devices - as are transmitted by the PC, the list contains only one entry (since
there is only one name).
This entry corresponds to dongle #2 address (STEP 6 overwrites STEP's 2 outcome
in its effects on paired devices list)
[Exception: if the name of the BT dongle device transmitted by the PC is
extremely long (>32 chars).
But then another bug presents itself where the entry corresponding for BT
dongle #2 is the full name (as transmitted by the PC). While the entry
corresponding for BT dongle #1 is the full name truncated to 32 chars.
This second bug eliminates the first one.]
EXTRA SOFTWARE INSTALLED:
Obviously this is not the common use case. But it's necessary if you have a
bunch of BT dongles (with different addresses!!) to use with a desktop
computer, and you randomly pick one each time.
Because the OS (in the case of Windows 7 at least) doesn't seem to remember
different names for the different dongles. So each time I plug in a dongle it
has the same name, unless I manually change it upon every plugin.
The Maemo 5 BT menu doesn't have this issue, since it allows to change the NAME
of the paired device. Interestingly, this is also the name seen, in the
ESTABLISH CONNECION menu of BlueMaemo.
A solution might be to associate every entry in the PAIRED DEVICES LIST with
the device's address instead of its transmitted name and/or allowing to edit
entry names in the list.
Thanks a lot!
