I have read in these forums that Nokia phones do not support multiple simultaneous Bluetooth connections unless all connections are initiated by the phone (in master mode). But I have run some experiments on my Nokia 6680, firmware 2.04.15 and the results point in another direction.
Here's what I did: first I connected a Jabra BT-250 headset to the phone. That worked great. Then I established a network connection from my PDA over Bluetooth and then the 3G connection (used the phone as a modem). Then I connected a Bluetooth GPS (i.Trek). And finally I started the Covelus Router software (uses the Serial Port Profile to get data from a Nokia SU-1B digital pen and route it to a server-side application). They all worked at the same time! So I was having 4 simultaneous Bluetooth connections: the PDA (dial up), the GPS, the headset and the digital pen. Only one connection was outgoing (the GPS), the rest of them had been initiated by the devices.
So can anyone tell me what's going on? Do all phones support this configuration or was I just lucky?
