Build instructions

This section outlines example instructions to build the Wi-Fi® radio test sample binaries for the nRF7002 Development Kit (DK) and Evaluation Kit (EK) kits.

Stand-alone Wi-Fi Radio test

For information on building the stand-alone Wi-Fi Radio test, see either the Wi-Fi: Radio test (Multi domain) sample or the Wi-Fi: Bluetooth LE Wi-Fi Radio test for nRF70 Series (Single domain) sample.

Combined build for Radio test and Wi-Fi Radio test

The combined build configuration builds the binary files for the Wi-Fi Radio test that resides in the application core and the Radio test (short-range) that resides in the network core. In the <ncs_repo>/nrf/samples/wifi/radio_test/multi_domain/prj.conf file, set CONFIG_NRF70_SR_COEX = y, CONFIG_NRF70_SR_COEX_RF_SWITCH = y, and CONFIG_SUPPORT_NETCORE_PERIPHERAL_RADIO_TEST = y Kconfig options.

$ west build -p -b nrf7002dk/nrf5340/cpuapp (DK build)

Note

Set sr_ant_switch_ctrl subcommand to 1 on the Wi-Fi Radio test UART port to switch the BLE RF signal to the BLE U.FL socket.

The following HEX files are generated:

  • APP core HEX file: /build/merged.hex

  • NET core HEX file: /build/merged_CPUNET.hex

The nRF5340 DK + nRF7002 EK cannot be used in Wi-Fi and short-range combined mode. Use it for either Wi-Fi or short-range testing only. The IOVDD and BUCKEN GPIO (P1.00 and P1.01) on the nRF5340 DK were originally meant for the UART1 interface and routed through the IMCU debugger chip. These pins are reused for the nRF7002 EK. Consequently, UART1, used for the short-range communication console, will not function and must be disabled.

Note

It is recommended to open solder bridges SB29 and SB30 on the nRF5340 DK when using it with the nRF7002 EK shield. If solder bridges SB29 and SB30 are open, UART1 functionality will be disabled, preventing short-range (network core) console output. Therefore, the modified nRF5340 DK along with the nRF7002 EK must be used for Wi-Fi (application core) testing.
