Advertising connectable: false stops advertising (nrf52832 dev board).

Hi @Gordon, I assure you I'm disconnected from the IDE. Here's a portion of the code (setup), since there's a bit more involved. If you know DMX lighting protocols, this is advertising code for DMX over Bluetooth. I've tested this with the last line commented out (turn off connectability), and there is no advertising. I've also tried changing the 'connectability' parameter in the initial setAdvertising with the same results: once I turn off conductibility, the device ceases to advertise.
