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.

I think the answer would be to propose the beacon to be part of the Bluetooth SIG specifications. Any group of 3 companies in good standing in the Bluetooth SIG (adopter or above) can propose this to the SIG. This is called a New Work Proposal. This can then be taken up by a Study group/working group to actually get the specifications adopted by the Bluetooth SIG.

Edit: This may be a better link as it shows the dcouments available in the Bluetooth SIG. https://www.bluetooth.org/en-us/specification/reference-publ...
