[8125, K-JAM, P4300, MDA Vario General] akirkby:
I've been having a discussion with TomTom support over the last few days regarding a problem with getting my Mini S to talk to a BT GPS Receiver and a BT HF kit at the same time. Tomtom have basically told me this won't work and that whilst Tomtom is installed - not even running, the phone will not work with a BT HF device....!!!! :?

Anybody else experience this? Are Tomtom saying that their software basically renders the phone useless with handsfree??? :shock:

I've included the conversation from Tomtom below :-

Note the entries are in reverse order.

Dear Mr. Kirby,

Since your PDA does not have any physical serial interface, a wired GPS-receiver (which runs through a serial interface) will unfortunately not be possible.

To further clarify our statement, your PDA seems to have difficulties sharing the same BT connection port and/or profile between multiple devices or services. This has nothing to do with our software, this is hard-coded into the operating system and hardware your PDA runs on. The binding of a BT serial port is a PDA function, not a software function.

We sympathise with your situation, but as we are not the manufacturers of your PDA or your carkit, there is very little we can do to assist you.

Kind regards,

Does this mean that if I use a wired GPS receiver then this will work? Or, are you telling me that once I install the Tomtom software on a PDA phone that I will loose the ability to use any other Bluetooth devices until the Tomtom software is removed? If this is the case then I can hardly see how you can claim compatability with the XDA series of devices, at least without notifying potential customers that they will loose all handsfree functionality via Bluetooth once you install the software?

Dear Mr. Kirby,

Our earlier correspondence was unfortunately not entirely clear. What we mean is that there is an internal conflict between our software, which is bound to the PDA Bluetooth Serial Port by the PDA hardware and underlying Windows OS), and your BT Carkit, which attempts to pre-empt the BT Serial Connection bond. This bond is enforced whether or not the program is actually active, and the ability to share a bound serial port concurrently is something that is enforced by your operating system.

This is unfortunately not something we can do anything about, since this is both hardware- and Windows-based (in the sense that multiple programs cannot access the same serial port concurrently), and also because we cannot provide technical support for a problem that is outside the purview of our software.

Kind regards,

Your answer makes the assumption that the problem only occurs when the Tomtom software is running. This is not the case. Before Tomtom was installed on the device it would connect to the carkit and work correctly. Following the installation of Tomtom it will no longer remain connected for more than 15-20 seconds, regardless of whether Tomtom is running or not. If Tomtom is running and communicating with the BT GPS receiver it does still not function correctly with the carkit, however, if the Traffic function is activated then it will maintain a connection.

I therefore suggest that your previous explaination is not accurate - I could possibly accept an issue with Tomtom running and it then disconnecting from the carkit however, even with the BT GPS receiver removed from the paired devices and switched off it will still not remain connected.

Dear Mr. Kirby,

Since we do not support the usage of third-party carkits (Bluetooth or wired/serial), we are only able to offer a technical theory as to your problem.

As your carkit is connected with a (virtual) Bluetooth serial connection, there is most likely an internal conflict with regards to the serial connection. PDA's support multiple Bluetooth profiles (methods of connecting), but typically bind the serial port to one device. Seeing this, the most likely culprit is the fact that the PDA keeps on switching focus between the two devices that use the serial port: Your BT GPS-receiver and the BT Carkit. When Navigator 5 is running, it pre-empts the serial port connection for the GPS-receiver, which forces the connection to stabilise.

Though we cannot offer you a solution to your problem, please try changing the settings of your BT Serial connection (removing the Authentication and Encryption options).

Kind regards,

I have recently upgraded from a O2 XDA II to an O2 XDA Mini S. The product has been working perfectly for a number of days with my Vauxhall(Opel) Vectra Bluetooth car kit. The phone will pair with the unit, the contacts are downloaded etc and the phone will remain paired and make/receive calls via the bluetooth unit until switched off.

Yesterday I installed TOMTOM (Details above) onto the main memory and the GB maps onto the storage cards. The software was activated and my Plus subscription reset for the new device.

TomTom works OK on the device and the traffic information is updated as expected. With TOMTOM running, a route active and traffic information active the phone will maintain a connection with the bluetooth car kit. However, if a route is not active and therefore the traffic information is not active, the phone will connect to the bluetooth carkit and then disconnect after around 15-20 seconds. If the carkit is forced to reconnect it will but once again it will disconnect after 15-20 seconds.

If tomtom is not running, when I go to the phone dialer screen, when I force the phone to connect the headset icon is visible again for 15-20 seconds but then disappears when the phone disconnects from the carkit.

Presently the only way I can keep the phone connected to the carkit is to ensure that tomtom is active with a route and traffic updates switched on.

As stated previously this behaviour only started when tomtom was loaded on the XDA Mini S. Presently there is no way to keep the phone connected via bluetooth unless tomtom is running as above. I am using a Mk I Tomtom bluetooth GPRS receiver.

Tomtom was patched using the updated software as downloaded last week.

I have tried various combinations of resets/ re-pair/ delete device etc on both the carkit and phone. The problem still remains.
