peripheral with simultaneous central connections?

Netanel Unger

Other Parts Discussed in Thread: CC2541

Hi,

I'm using CC2541 with stack 1.40, And enabled the +broadcast mode so the peripheral keep advertise while in connection, but a second central could not bond to the peripheral.

There is a way to enable more then one central bonding to the same peripheral? (and reading/writing characteristics)

Thanks.

Could You possibly point out where this limit can be found in the specification?

I tried to locate it, but just could not find...may have missed something...

I was incorrect in my previous post. My statement was true for Bluetooth 4.0.

For Bluetooth 4.1, peripherals can be connected to more than one central device. TI has no plans to adopt the Bluetooth 4.1 standards for the CC254x http://e2e.ti.com/support/wireless_connectivity/f/538/t/381224.aspx

You can find the specs here https://www.bluetooth.org/en-us/specification/adopted-specifications

Fine, because after almost 1 year of the v4.1 specification adoption IMO you should have clarified that this is not something, that the current specification does not support...it was unnecessarily misleading...

Its only a TI specific boundary.
