Can I create a master and slave in one device?

[Peter Verheij]

I would like to create a unit which is intermitting in the master and in the slave role.It should be most of the time "advertising" and waiting for some master to connect to it i.e. slave role.But every now and then it should leave this role and become a master and try to connect to another slave. Can this be done in a single device? wil it need to swap softdevice S110 / S120 every time?

For your application, I'd recommend you to take a look on the S310. This is a softdevice that is able to concurrently keep a BLE link, while being able to communicate with other ANT devices. This softdevice can be used with the latest revision nRF51422 chips.

Another option can also be to keep using S110 for the smartphone connectivity, but use a proprietary connection with the other devices. Be aware however that current softdevice does not allow you to do such proprietary communication while a BLE link is established.

Please contact our sales manager for your area for details on sampling nRF51422, or information future plans for the S110. PM me your location if you don't have his contact information.
