communication with more, then 8 devices

[sevastianovd]

hello,
i have 50 devices around the server. communication is via bluetooth spp, use MS BT stack.
after connection device is comes to undiscoverable mode.
the communication is short command (a few characters).
i need very fast connect & disconnect from server to devices, that all devices can communicate.
is it possible by WCL lib?

[Mike Petrichenko]

Yes of course. Find all devices then connect to each (you can connect to 7 devices at one time).

[sevastianovd]

will the virtual COM-port up? or communication will be without COM-port? what time is need to connect (best variant)?
about "Find all devices", BT receiver can`t see more, then 7 devices, isn`t it?

[Mike Petrichenko]

Use wclClient to communicate with your devices (see BluetoothConnection demo). Connection time depends on hardware (BT dongle and remote device), distance, how many other devices work on the same frequency and lot of other factors. BT Receiver can find all devices but can't connect to more than 7 at the same time.

is it really to have 0.1 sec to connection in favorable conditions?

[Mike Petrichenko]

I afraid it can't be so fast.
