Does BLE master have to send separate connection packets to peripherals?

In basic terms, when a Bluetooth low energy master connects with a peripheral BLE device, a connection packet is sent every specified connection interval, and the peripheral responds back if in range. But if the BLE master is connected to TWO BLE peripherals, does the master have to send out connection packets... show more In basic terms, when a Bluetooth low energy master connects with a peripheral BLE device, a connection packet is sent every specified connection interval, and the peripheral responds back if in range.
