One option is to alternatively switch between both broadcasts on a single radio.

You broadcast a single iBeacon-only message, sleep for a few hundred miliseconds and then broadcast a new AltBeacon message.

The beacon does this so quickly, that it's usually sending out two or three of both kind of messages every second. It's effectively an iBeacon + AltBeacon in one device.

You can use this example to send this example code on github to run multiple advertisers. (May be a bit of overkill to just send 2 kinds of beacons but does provide accurate timing control over the beacons). http://nordicsemiconductor.github.io/nRF51-multi-role-conn-o....

However it is really a waste of energy to send 2 types of beacon packets when one should suffice. However it is technically possible.
