To support older, pre 2013 smart phones, can our peripheral advertise original Bluetooth (3.0) and same time, or alternating with advertising Bluetooth Low Energy (4.0)?

Peripheral will only connect with BLE central, and should ignore connection attempt by original Bluetooth central.

BCM2073x is BLE single mode device.

It can't send any Legacy Bluetooth packets.

Legacy Bluetooth master which is not dual mode device can't receive BLE advertisement packet from 2073x.

So we don't need to care about wrong connection with legacy devices I think.
