Bluetooth, GSM, and Gameboy
brnsurgon1 writes ""The aim of the project was to investigate mobile gaming over GSM- and Bluetooth- networks, by developing a concept prototype, connecting a Gameboy to a mobile phone over Bluetooth. The results show that it is possible to connect two Gameboy Color over a GSM network by connecting to the phone using the Bluetooth plugin we developed for the Gameboy."" A couple other have submitted this story - it looks interesting. But, heck, I'm still trying to finish Golden Sun on my GBA.
can i connect a gb advance sp with a normal gb advance or a gb color?
Why not? it's the same device in a different case.
Did anybody notice that the thesis was done in 2000 and the last update to the page was two years ago?
It is interesting anyway because the thesis contains all the diagrams and explanations needed for building your own interfaces. But this is not really new...
...that's doing bluetooth on the GBA, but for a lot more than playing games. Their "edutainment" angle makes me suspicious, but they've got some interesting looking features.
My company has developed the GPRS-based Chess game that comes bundled with the O2xda (essentially the same as the T-Mobile Pocket PC in the U.S.). It works extremely well, using connectionless UDP via GPRS packets. The game only sends tiny little packets when you chat or make a move, and as far as we have seen there is not even packet loss on a GPRS network. The costs boil down to about 1 EUR/US$ per hour of play. The only problem is that the device still costs EUR 500.-, so it's not really a mass market product. But expect things to change, my guess is that there will be plenty of multiplayer mobile games by summer, at least here in Europe.
> It looks like some phone companies have decided to charge for GPRS access based on time, not on volume of traffic.
thats bad. very bad.
first, it is important to understanding how GPRS works. telco's will put higher precedence over voice calls than GPRS calls - so, if the network is full, they will disconnect GPRS connections to allow voice connections to go through (this, depends on the network of course - but, when you understand more money can be made from voice calls - its obvious).
paying by the minute for a GPRS connection is stupid. the whole idea with GPRS was to stay connected at all times, and, receive data as soon as it was available; when i tested GPRS way back in 2000, it was cool to be able to ride the subway/bus to work, and, continue to icq my buddies (sad, i know; but it had a geek factor to it *g*).
the second problem with GPRS is that although there may be more bandwidth available - its a common misconception that in reality, you are actually sharing bandwidth with others. that means, if 10 people are sharing a 144kbps line, your connection may effectively be 14kbps. keep in mind that normal GSM phone call you pay by the minute, but, your guarenteed a connection of 9600bps. while doing tests with GPRS and GSM, i found, when in congested areas - i got better transfer rates with GSM (dialing isp) than GPRS. it isn't hard to do the math and figure out at which point GPRS actually becomes slower than using GSM.
the true fun will come when they can stablise UMTS. but, that is well overdue - constant delays, hmm.. i wonder why?
