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?

Another option: You can use the nRF51 as a master device and the temperature sensors as broadcasters so no connection is required. The nRF51 will work well with the iOS phone/tablet, where the iOS is a slave device (iOS in peripheral role) The only limitation is that this is an iOS only solution until Android supports a slave option in addition to the master option.
