Bluetooth Connection Trouble.

[Impret-Sir]

Hello,
Recently bought a second hand Xperia Z5 Compact to replace my old HTC Wildfire S. I have been trying to transfer my contact list from the old phone to the new via Bluetooth. Although they will 'pair' without trouble they wont 'connect'. I thought it might be a range thing, but I have them literally inches apart, makes no difference! Any suggestions? I don't want to have to type them all in manually! (and my pictures/texts too)!

Maybe buenchico will help with this. He is good at finding out these things

Do you not have a Google account?
If you have a Google account, if you were signed in on your other phone, any new contacts would have been added to your Google account (assuming it was all set up correctly, etc) ..... then when you buy a new phone, you simply log on your Google account and import all the contacts.

Are the bluetooth "versions" on the phones compatible? Bluetooth is supposed to be backward compatable so a newer version should pair and connect with a older version. However they also both need to be using the same hardware and software. Also if the newer phone is using Bluetooth Smart it will not connect with a phone that does not use the protocol.

Hmm. The Xperia appears to utilise Bluetooth 4.00 and the Wildfire 3.0. However the specs say that the Xperia 4.0 protocol is a "low energy" system. I suspect that this may be code for "smart". Like all our low energy solutions then, not always so smart. I think I would firstly check whether there are any system updates available for the Xperia as these issues were apparent some time back and patches were issued by Sony to overcome them.

wow, thanks for the prompt and knowledgeable answers. I didnt know there were different Bluetooth versions. Never heard of Bluetooth Smart either! The HTC is ancient, (in tech terms), so is certain noto to be using the same version as the new phone. Togo, what did you mean when you wrote that, "However they also both need to be using the same hardware"?

The hardware in a mobile phone, like a pc or laptop, is the processor, graphics, RAM, etc. Basically manufacturers are liable to use matching chipsets across their ranges. For instace an Apple smartphone is liable to have more problems pairing with a Samsung android, even using the same Bluetooth version, than it would with another Apple phone.
