Hi,

In total the nRF9160 has 4 UARTE instances. UARTE0 to UARTE3. UARTE0 is used for console, and routed out to VCOM0 port on the DK. For the lte_ble_gateway sample we use UARTE2(default) to connect to the nRF52840 (BLE HCI). For the other samples, we don't use UARTE2. UARTE1 can be used to take modem traces (if enabled). UARTE3 is not used in any of the samples.
