I am generally satisfied with my T-mobile G2x, but I find I cannot connect over bluetooth with an external Bluetooth GPS. Has anyone had this problem or fixed it? I cannot even see the GPS device when I scan for devices. Two other colleagues tried with their Android phones (both less than 1 year old), and paired and connected no problem, but my G2x (Android 2.3.3) can't even see the device when scanning. I can connect fine to multiple bluetooth headsets, and can see PC's and Mac's bluetooth when I scan for devices. But no luck with Bluetooth GPS.
Has anyone done this successfully with the G2X? Can anyone help?
Working on this further, I don't believe an external GPS is possible with this phone and the T-Mobile firmware, despite talking to LG and having the LG service tech assure me that SPP (Bluetooth using Serial Port Protocol) is supported on the G2x. If this feature is important, I think the only choice is to flash a new ROM (e.g. Cyanogenmod 7) on the device (which may void the warrantee).
Have you tried using an app called Bluetooth GPS?
Actually, that works but I've not been able to get Google Maps to recognize the external GPS device as the GPS source. However, Bluetooth GPS Provider, which is also in the Android Market, works seamlessly with Maps.
Sorry, I was responding to your second post, but backtracking to your original post, I see that you had problems with the basic pairing, which these apps will not be able to help with.
You're right, Bluetooth GPS (which is a very helpful program) doesn't help at all if you can't pair to the device. Once I can pair, Bluetooth GPS (as you know) allows you to "mock location" or whatever they call it, so you can view in Google Maps. But Bluetooth GPS contained nothing that could overcome the basic pairing problem.
If you do get the pairing fixed, try Bluetooth GPS Provider. It immediately worked with Google Maps, while Maps continued to try getting its positioning via the internal GPS with the other app, even though the signals were loud and clear.
The latest nightlies of CyanogenMod look like they support external bluettoth GPS devices natively.
You are correct about CyanoGenMod 7. It does work with external Bluetooth GPS. Obviously it isn't a hardware problem, it's just the standard T-Mobile/LG ROM is buggy. The Catch-22 is T-Mobile and LG both claim they support this, but it doesn't work and they can't figure it out, and I've read the G2x is End-of-Life, so they don't much care anymore. But if you dare flash the CyanoGenMod, T-Mobile will void the warrantee. So you keep an old copy of the T-Mobile ROM around, I guess, and flash it back in if the phone need to go back for warranty repairs...
Actually it would be LG that would void the warranty, T-Mobile only sells the phone not make them.
