The host application runs on an nRF54 Series DK and talks to an nRF9151 DK or nRF9151 SMA DK (Serial Modem) over UART with hardware flow control, DTR/RI, and an optional modem reset line.
The nRF9151 SMA DK uses the same board controller, GPIO pinout, and build target (nrf9151dk/nrf9151/ns) as the nRF9151 DK. The only hardware difference is the SMA antenna connector instead of a PCB antenna - wiring is identical.
The application supports the following host boards:
| Host DK | Serial Modem wiring |
|---|---|
| nRF54L15 DK | P0 connector (uart30) |
| nRF54LM20B DK | P1/P2 connector (uart21) |
| nRF54LM20B DK + nRF7002-EB II (Wi-Fi® location) | P1/P2 connector (uart21) |
