To use UART 1 via Arduino headers, the virtual UART of the J-Link probe needs to be disabled, e.g. with the JLink Configuration Tool.
## nRF54L15
### HCI over UART 0 connected to second Virtual UART in J-Link Probe
Release build:
```sh
west build -d nrf54l15-iso --pristine -b nrf54l15dk/nrf54l15/cpuapp
```
Debug build:
```sh
west build -d nrf54l15-iso --pristine -b nrf54l15dk/nrf54l15/cpuapp -- -DOVERLAY_CONFIG=debug.conf
```
### Pinout
Signal direction as seen from the nRF54L15.
| PIN | MCU | Direction |
|----------|-------|-----------|
| TX | P0.00 | out |
| RX | P0.01 | in |
| RTS | P0.02 | out |
| CTS | P0.03 | in |
| Time Sync| P1.11 | out |
## Maintainer Notes
nRF5340 use Controller configuration in `sybuild/ipc_radio/prj.conf`, while other, e.g. nRF54L15, use configuration in `le-audio.conf`. Please update both at the same time.
We can check the nRF5340 SoC with `if(CONFIG_SOC STREQUAL "nrf5340")` after find_package zephyr.
