Sod the headset profile, Is anybody here using the Bluetooth SPP?
I am, its ideal for small data transfers, such as between a phone and a bluetooth GPS receiver. But it seems now GPS is being added to more and more devices, this may become less attractive.
At the mo, it saves me shelling out more cash for a TomTom Go.
All I need do before long car journeys is take out my BT GPS receiver, plonk it on my dashboard under the windscreen so it has a good signal, then fire up TomTom on my HTC Tytn 1 mobile phone (the earlier TyTn without built in GPS) and put the phone in my in-car cup holder! Job done!
TomTom also switches on your BT adapter in the phone, so once initial set up is done, you dont need to sod around switching things on and initiating connections before launching the satnav software.
Fantastic. Connection initiation is quicker than the GPS can lock onto satellites even during warm startups.
Its ideal because I can put the GPS in the position best suited for GPS signal acquisition too.
Bluetooth is far from being defunct. I never saw it as direct competition with WiFi, its just not for that, whatever happened to the PAN acronym? It was inevitable that most of the profiles would not be adopted anyway.
Bluetooth SPP is also great for hobbyist electronics / robotics work too - there are small modules you can buy which just act like serial ports to microcontrollers! Great fun and far better than trying to get a low end microcontroller to talk USB or a full WiFi TCPIP stack set up.
