dear Forum,
is there some kind of limit to the number of Arduinos Bluetooth that can be connected to a single computer, using Bluetooth, not USB? I need to connect 6 to 8 Arduinos to a single computer, and I am looking for the best solution to my case.
thank you,
andrei
Hi andrei,
according to http://en.wikipedia.org/wiki/Piconet:
These days, a piconet is an ad-hoc computer network linking a user group of devices using Bluetooth technology protocols to allow one master device to interconnect with up to seven active slave devices (because a three-bit MAC address is used). Up to 255 further slave devices can be inactive, or parked, which the master device can bring into active status at any time.
Piconet range will vary according to the class of the bluetooth device. Data transfer rates vary between about 200 and 2100 kbit/s at the application, depending on whether synchronous or asynchronous connection is used, and the number of devices in the piconet.
So theoretically 7 Arduino slaves can be used.

Thank you, Mike.
